How To Prepare Or Plan For A 100 Mile Ultramarathon (Or Similarly Long Ultra Run)

As I prepared for months for my first-ever 100 mile run, I did a lot of research to figure out how I should be prepared. There’s no one way to “prepare” for an ultramarathon of any distance, and much of the stuff online is about your training plan and physical preparations. Which is definitely important, but not the only thing that needs preparation.

After a lot of reading, thinking about my own plans and preparation, I’ve realized there are 4 general types of preparation for an ultramarathon that I’ve been doing: mental preparation and training; nutrition preparation and training; race day strategy preparation; and the actual physical training and running to prepare for an ultramarathon.

Usually, blog posts either cover the last category (training plans and physical training philosophies) or one of the other categories. This blog post summarizes everything I’ve done in all of these categories together in one place – in part to help me if I ever run another ultra following my first 100 mile attempt!

Almost everything I thought about and planned for a 100 mile ultramarathon, by Dana M. Lewis on DIYPS.org
  1. Mental preparation and training

It’s commonly said online that running 100 miles (or most ultra distances) is 80% mental and only 20% physical. (Or similar splits like 90/10). This is in part because it is not feasible to physically train to run the distance prior to your race (usually); and the first time you tackle a new distance, you always have many (often dozens!) of miles of distance that you’ve never covered before. It’s going to be uncomfortable, and you have to plan for that. Thus, mental preparation and training as much as possible to be prepared to deal with these challenges.

The first major aspect of this, for me, is practicing and reminding my brain how to process and work through discomfort. Discomfort is distinct from pain and being injured. (Pain and an injury should include evaluating whether you should cease your activity.) I’ve fortunately (and unfortunately) had recent experiences of pain when I broke my toe. Returning to walking and then running involved some discomfort as my body got used to covering miles again. It was a very distinct feeling that was not easily confused with pain from a broken bone, which to me feels like an “electrical” type of feeling.

This recent experience with pain is easy to differentiate from the discomfort of running long distances and being tired and sore. I’m working to capture these thoughts when I have them, and transition from “I’m tired and this hurts and this is terrible” during training runs and convert these thought patterns to “I’m tired and uncomfortable. But this is not pain; this is discomfort. This is how I’m going to feel at mile 34 or 57 or the back half of my 100M, and I’m going to keep running then and I’m going to keep running now to practice this feeling.” I want to register and save this feeling and mental state for what it’ll feel like during my 100M, so it’s easier to pull that out when I’m exhausted and uncomfortable at 3am and still likely have another 40-50 miles to go.

Similarly, I also try to envision different scenarios that I will experience in my “race” or 100 mile experience. In my case, I plan to run on a paved trail for a solo endeavor (DIY or self-organized, rather than an organized race with other people). Some of the scenarios I am expecting to experience and deal with include:

  • I will be running a course with 7 “laps” or loops of various lengths. This involves me coming back to the same point seven times so that I can get re-fueled by my crew (my husband), change clothes if needed, etc. I envision coming in for my second or third lap, having to turn around to head back out for another (but not my last) lap and not wanting to leave.
    • How I planned to deal with this scenario: I’ve written down crew instructions for my husband, which include how to refuel and replenish my supplies; a list of troubleshooting scenarios and supplies; but also specific things that would be constructive to say to me. In this instance, any of the following:
      • You are strong and you can do this.
      • You only have to do the current lap.
      • Walk as much as you need to.
  • This 100M will be one of the first times (other than a training run where I practice the transition) running all day and into the the night. I’m a little apprehensive about this idea of running for 14 hours in the dark (due to the time of year). Partially, this is because I’ve never run 14 hours before, and I’ll be doing it after already having run for 10 or so hours! And because I’m not as experienced running in the dark.
    • How I planned to deal with this scenario: I have a clear set of “day to night” transition supplies and instructions to gear up for the night. I will be equipped with reflective components on my vest; a bright colored shirt; a waist lamp; a head lamp; a blinky red light on the back of my vest. I will focus on getting geared up and recognizing that it’s a mental transition as well as a physical gear transition. I will also try to think about the novelty and adventure aspects of running through the night. It’ll probably be wet and cloudy – but it might clear up in patches enough to see some stars! And – the running through the night is something I didn’t think I could do, which is actually why I’m doing a 100M, to prove to myself that I can do anything I want to set my mind to. This is the purpose of being out here, and it’s a necessary part of achieving 100M.
  • At some point, most people do a lot of walking. I’m fairly unique in my “running” approach – I run/walk from the start, and also not like many people run/walk. In ultras, most folks walk every X minutes or when they reach hills. I consistently run/walk with 30s of running, then 60s or 90s of walking – from the very start. These are short intervals, but it’s what works well for me. But like everyone else, regardless of initial strategy, I expect there will be a time where it might be more efficient to try a brisk, consistent walk for a few minutes (or miles!), or a slow slog (inefficient walk) because that’s all I can convince myself to do.
    • How I planned to deal with this scenario: The goal is forward motion, however I can move. Walking is ok, and expected – and I will remind myself of that. I know there is a crossover point when running speed slows down to a certain degree and running becomes as efficient at a certain point. I also know these points, speeds, and effort levels will change throughout my 100M. It helps that I’m already a proactive walker; I have no shame, guilt, or hangups related to walking because it’s ½ or ⅔ of my forward motion strategy from the start! But I will remind myself that my plans for intervals can change and I can experiment to see what feels good throughout.
  • It’s possible that I could trip and fall, especially as I get tired and scuffle my feet on the trail, even though I’m on the paved trail. I also might get swooped by an owl or startled by something which causes me to trip and fall unexpectedly.
    • How I planned to deal with this scenario: I’ve got my safety plan in place (more on that below) and know I will first while on the ground disable the alarm on my watch so it does not call 911 (assuming this doesn’t appear to be needed). I will move my body to see if I’m just sore or if there are any scrapes or injuries that need addressing. I will stand up if possible, continuing to check myself out. I will slowly walk, if possible, and see how I feel. I’ll also probably call and let my husband know, and either ask him to come meet me earlier than expected that lap or just let him know so he can check on me when we meet up as planned. I will let myself walk any soreness off for a while (and turn off my interval alerts) before resuming a planned run/walk strategy.

So these are some of the scenarios I’m envisioning dealing with and my plans for them, with the hope and expectation that my brain will be better equipped to deal with them as a result of thinking about them in advance.

Depending on your race/route/plans, you might need to add other types of scenarios – such as leaving the aid station with warmth and light before heading into the night; or what to do if your crew doesn’t show up as planned; or your drop bag gets soaked with water; or the aid station is out of supplies or there is no one where you expect an aid station.

The other part of my mental preparation is a lot of pre-problem solving. Similar to the above scenarios, I have thought through what I need to do for the following:

  • I drop my fuel, enzymes, or electrolytes and can’t find them.
    • How I planned to deal with this scenario: I will call or text my husband and adjust plans for where he meets me. I will use the backup fuel supplies in my pack as needed to tide me over. (For my race, I have fuel in individual baggies and separated out for each “lap” or segment, plus extras and backups, so my husband can grab the backup bag or the next lap bag and bring it to me.)
  • I run out of water.
    • How I planned to deal with this scenario: There are 3-4 water fountains along or nearby my planned run route, and I can re-fill my hydration bladder within ~3 miles from any spot on the trail. I can also again call my husband and have him meet me sooner to re-fill my hydration pack.
  • My stomach gets upset.
    • How I planned to deal with this scenario: I have supplies (such as Immodium, GasX, Tums, etc) in my running pack that I can use. I also have more supplies laid out at home that I can ask my husband to bring.
  • I don’t feel like eating.
    • How I planned to deal with this scenario: I included this on the list because I read that it happens to a lot of people. But, as a person with type 1 diabetes…I have 20 years of practice of consuming sugar or food when my blood sugar is dropping or low, even when I’m not hungry. I have also practiced consistently fueling throughout my long runs, and I am used to eating when not hungry. I expect it is more likely that I will get tired of certain textures, so I have planned out my fuel so that “harder to chew” or crunchy foods that might hurt my mouth are the snacks I eat earlier, and then eat softer snacks or snacks that require less chewing later in the run. I also have a variety of backups that include different textures and some liquid options that I can substitute for my planned fuel.
  • Other scenarios I’ve pre-problem-solved are getting blisters or sore spots on my feet; chafing; getting low on sodium/electrolytes; muscles hurting on other parts of my body other than my feet; having feet that swell; getting itchy or having other types of allergic reactions; having trouble breathing; my eyes hurting; being really tired; being hot or cold or wet; my blood sugar staying higher or lower for a longer period of time; and mentally feeling “low” and unmotivated and wavering in the pursuit of my goal.
    • How I planned to deal with this scenario: As part of the ‘crew instruction’ list I’ve made for my husband, I have listed out all the supplies I have to address these categories. I will also have all of these supplies grouped and set out at home. My husband is awesome at troubleshooting problems in general, but he’ll also be tired at 2 am after only sleeping for 2 hours (plus I will be tired), so I created this to help me prep all the gear but also when I tell him “I’m ____”, he can offer the requisite supplies to address the problem without me having to try to figure out what my options are and decide what to do. All of this is to help mitigate the decision fatigue I will have and the overall fatigue he will have.
    • Note: I’ve also previously read a really good tip about managing decision fatigue. Tell your crew – in my case I’ve told my husband and written it onto the crew sheet – not to ask open-ended question, but to offer specific suggestions or options. For example, say “Do you want 2 or 2.5 liters of water in your hydration pack?” instead of “How much water do you want?”. For refilling my snacks, I’ve told my husband to refill my snack pack from the pre-filled bags, but the bag also has a sticky note about grabbing fresh prepared food. I told him to specifically ask “Do you want your waffle; sweet potato tots; mashed potatoes; or” (whatever is on my list of pre-prepared food for him to make and bring), instead of “What do you want?”

A lot of these I put on my list to think about based on race reports I’ve read from other people, that covers what they experienced (e.g. feet swelling and finding it helpful to have a half size bigger shoe to change into) and how they troubleshot things during the race while in between or at aid stations.

Some of my favorite race reports/blogs that I’ve learned a lot from include Rebecca Walker’s race reports; Wes Plate’s race recaps; Debbie Norman’s race reports (check out her sample crew sheet in that linked post); Bob Hearn’s thoughtfulness around pacing and walk strategy; and Sarah Lavender Smith’s race reports.

I have learned quite a bit and improved my planning and preparation by reading race reports of DNFs and also of finished races of different lengths. The longer the race, the more challenges there are and the more time to learn and sort them out. So that’s why I appreciate reading Wes’s multi day (eg 240 mile) recaps as well as 100 mile race reports, even though my focus has been on 50ks previously and now “just” a 100M.

One other thing I’ve thought about is the importance of knowing what your criteria for quitting/stopping/DNFing. For me this links back to discomfort versus pain. An injury should involve stopping temporarily and maybe permanently. But being tired, sore, uncomfortable – for me those should not qualify as reasons to stop. My goal is not to stop before 100 miles unless I have an actual injury (eg broken toe level pain).

2. Nutrition preparation and training

Yes, it’s worth “training” your nutrition. This means training your body by practicing fueling with the same foods and strategies as you want to use on your race. There’s a mantra of “nothing new on race day” that is both useful and not applicable to ultrarunning. In general, a lot of ultrarunners seem to do well (per my above search through many race reports) with eating small portions of “whatever looks good” at aid stations. If it looks good, their body is probably going to deal with it ok. But not always. And a lot of time people will bring fuel and rely on things they haven’t tested on their long runs prior to race day. Don’t be that person!

  • Test your fueling options and strategy (e.g. timing of fueling) on most runs, not just your very longest runs. For me, I do fuel for any runs of 2 hours or longer, because that correlates with when I bother to bring hydration and therefore also bring fuel. (That’s 8 miles for me at an average 15min/mile pace). Some folks use 1 hour or an hour and a half as their cutoff. But the point is – don’t just test your fuel on 6 hour runs. Fueling on shorter runs helps those runs feel better; you’ll likely recover from those runs more quickly; and it helps your body practice with those fueling options. You don’t want to find out at hour 8 of your 36 hour race that your body doesn’t do well with ___. It’s better to find that out at hour 3 of a 4 hour run, or similar.
  • Create your list of fuel that works for you. This should be based on your preferences but also how it helps you meet your fueling goals. When you have an idea for a new fuel, make sure you take it on your next run and try it. If you’re like me, you might want to try it near the end of your run, just in case your body doesn’t like it while running. If your body doesn’t like it, cross it off your list. You don’t want to be hauling or trying to eat food you know your body doesn’t like during a 100 mile run! I’ve found some things that I like to eat and found tasty fresh out of the oven – like ½ of a GF banana bread muffin – felt terrible in my mouth during runs. Some combination of the dry muffin (vs. freshly moist out of the oven) and the taste was not ideal for me. I ate it, and didn’t have GI distress, but I got home and promptly moved the remaining half portioned muffin baggies to my husband’s section of the fridge/freezer where my snack rejects go, and crossed it off my list. If it doesn’t bring you joy, or if it makes your brain cranky, it’s probably not a food you want for your ultra.
  • Don’t feel like there is a “wrong” food, as long as it’s something that’s not going to spoil easy or melt or be too hard to eat on the go. Look at snacks and meals you like to eat; is there a serving size or a variation that you like to eat? If so, try it! People eat all sorts of things in ultras, from puréed fruits and vegetables like applesauce or baby food pouches, to candy and chips to hamburgers and soup. Walk the store aisles (physically or virtually) and get ideas for food to try. But don’t limit yourself to sports “products” like blocks, gels, gu, drink mix, and similar. You’d be surprised about the variety of food that is portable, and in individual portions is close to the same macronutrients (calories, carbs, fat or protein, sodium, etc) as more expensive sports products. A lot of time you are paying for convenience and a certain texture/delivery method. But you can achieve the same intake of macronutrients through a variety of foods and beverages.
  • Some people stick with 1-2 foods or fuel sources (like liquid calorie/electrolyte solutions or gels/gu/blocks), but get tired of the sweet taste or the taste/texture of what they’re eating. Having a variety can help with this. Make your list, and for each run make sure you’re working through trying out and approving or removing the foods that you want to use during your race. Ideally, try them 1-2 times before your big run.
  • If you can, practice with some of the aid station type food including warm food (eg quesadilla or burger or whatever). Have someone meet you on longest runs with this freshly prepared, or take it with you and eat it for your first fuel. (Watch out for food spoiling/going bad – I always eat the hot/fresh prepared stuff first out of my set of fuel options when I get my pack refueled, to reduce the chance of bacteria growing or the food otherwise spoiling.) This is harder to do and may not be possible, but it could help expand your options for what you’re willing to take at aid stations if you’ve tested a version of a similar food before during a training run.
  • More planning ahead on nutrition for race day and training runs: figure out your timing of nutrition strategy and how many snacks or how much fuel (liquid or otherwise) you need to consume each hour or segment or between aid station. Pre-portion your fuel/snacks and if possible, label them. Plans can change and you can adapt on the fly, but having everything pre-portioned and ready to go means you can more easily start your training runs, fill your drop bags, or prep bags for your crew by having everything portioned out.
  • Planning ahead also means you get to the store or order however much you need so you’re not adding stress the last few days before you race or run in order to have your fuel set up and ready to go.
  • Don’t be afraid to use a timer. Some people wear running GPS watches that have alert/alarm features for fueling. You can use regular phone alarms, too, or apps like “Timer+” or “Intervals Pro” – both are ios apps that have free versions that allow one alarm each. You can choose whether it pushes a notification to your phone or watch or provides a verbal audio alert. I use both these apps and have one alarm that’s verbal audio reminding me to take electrolytes every 45 minutes; and the other one is a push-notification only that helps me remember to fuel roughly every 30 minutes. I generally am checking my watch so it’s easier to remember to fuel every :30 and 1:00 from when I start running, which is why I choose that one to be a push notification just in case. That works for me, but figure out your ideal timing and alert/alarm strategy to help you remember to fuel and electrolyte as you need to.

If anyone is curious about my individual approach to nutrition, I’ve written a bit more about it here, including how and why I actually use a spreadsheet to track nutrition and fueling during ultras and training runs. I separate my hydration (water only) and electrolytes (electrolyte pills; plus tracking the sodium in what I’m eating), so tracking my fueling serves many goals both during a run and after a run when I can look back and see if I need to tweak anything (such as not putting two smaller/lower-calorie, lower-sodium snacks back to back).

Since I’m running my ultra solo/DIY, I’m taking advantage of some fresh/heated fuel options, like mashed potatoes, ¼ of a ham and cheese (gluten-free) quesadilla, etc. For these, I am leaving a pre-printed sticky note on the baggie of shelf-stable fuel with a reminder for my husband to bring 2 of my fresh/hot options each time as well as anything else I need him to bring for that lap. To aid the bringing of the fresh/home food, I made a printed set of instructions that lists what these are, broken down by location (freezer, fridge, or on the counter) and instructions on how to make them. This is a critical step because what he predicts I want or how I want something to be cooked or prepped for a run doesn’t always match what I was wanting or expecting. Having clear instructions he can follow (eg heat ¼ quesadilla in microwave for 30s) works well for both of us and further helps with limiting his decision/processing fatigue since he’ll be responsible for grabbing and making 2 things; getting the lap bag of refuel; packing up ice and water; and getting all that and any other requested supplies out to the trail on time to refuel me as I pass by again.

If you have crew, think similarly about what food you want to have; how they’ll make it and serve it to you; how you’ll consume it at the aid station or as you move along on the trail. All of this planning will pay off.

(Another benefit of my macronutrient/fuel tracking spreadsheet is that my husband has access to it and can check it to see if I’m sticking to my fueling and electrolyte strategy, so he can troubleshoot and recommend things if I need support in fixing a problem. I don’t think he’ll use it much, but this secondary use of the spreadsheet was inspired by one of Heather Hart’s many excellent ultra posts talking about showing her empty fuel wrappers to her crew to prove that she was fueling. In my case, instead of counting wrappers, my husband can check my spreadsheet.)

3. Race day strategy (and pre-race and post-race strategy)

Continuing on the theme of pre-planning and laying out your strategy, I also think about strategy related to race day and leading up to race day as well as after race day.

My goal is to eliminate stress; pre-do as much work as I can physically and mentally to reduce the load when I will be physically and cognitively fatigued and overloaded.

Pre-race

For example, I look at my schedule prior to the race and try to clear out stressful activities (or prevent scheduling them, if possible). I know I’ll need to spend hours physically prepping (per above, making fuel and organizing supplies), so I put that on a to-do list and make a block of time on my calendar for it. I think about tasks that I will have before and after the race, such as changing my continuous glucose monitor (CGM) and pump sites to be in optimal locations on my body for the race; but also changing them early enough prior to the race so that they are settled in and I know they are working well. I also do things like pre-fill my reservoirs with insulin, and do enough reservoirs for a few days before and a week or so after the race. Like during the race, anything I can do to help reduce cognitive fatigue or pre-do steps of tasks that I know I will find harder to do is the goal.

This includes also blocking off my schedule with reminders to go to bed earlier. I think about when I’ll be waking up on race day and the night before, set my bedtime reminder for about 8 hours prior. Then every day before that I set it 15 minutes later, working back about a week and a half. I don’t always hit these sleep times, but progressively slightly shifting my sleep like this has been effective prior to international trips with a lot of time zone changes and also has paid off for getting a better night’s sleep the night or two before a race that involves waking up early.

I also specifically think through all the steps from waking up to starting my race, and how to optimize those. I eat a particular breakfast prior to the race, time it so that I can best get some macronutrients in, and time the insulin so I don’t have much of a BG spike but also then don’t have much insulin activity happening when I start my run. I don’t always get this right, but I attempt to line up my schedule so that I wake up and immediately eat what I have laid out on my bedside table and start hydrating, so that I can sleep as long as possible and don’t have to spend extra minutes convincing myself to get out of bed to go make breakfast. Some of these strategies are unique to me being a person with insulin-requiring (in my case, type 1) diabetes; but it’s pretty common for other ultrarunners to have strategies around what to eat the morning before a race; how many hours prior to the race; etc. I’d suggest you decide based on first principles and your own knowledge what to do for you.

Pro tip/personal vent: most people who blog or write about “avoiding insulin spikes” prior to the race or during the race – if they don’t actually administer exogenous insulin (aka inject or pump it, their pancreas makes it) – they also don’t usually actually know anything about the insulin response to food in their body. They are mostly repeating that from hearing it from others who repeat it from a long chain of people. You are SUPPOSED to spike insulin in response to what you’re eating: that’s good because it manages your blood glucose levels and helps your body process and store what it needs to be storing. It is also very normal for your blood sugar to rise in response to eating. The only people who need to think about “insulin spikes” are people who don’t think about it as insulin “spikes” but as insulin activity or more commonly “insulin on board” (IOB), which are people with insulin-requiring diabetes. This is different for us because we have to inject/pump insulin separately (our pancreases don’t make it on demand in response to sensing food in our bodies) AND because the insulin we use takes longer to act – 45-60 minutes instead of mere minutes – as well as has an hours-long “tail” effect. So it’s a lot of work to match the peak timing of insulin to the impact of different types of food in our bodies as well as watching out for insulin “stacking” over the many-hour activity curve for each dose. Your body, if you don’t have insulin-requiring diabetes? It does this, on its own, like magic. Yay, you! So ignore the stuff about “avoiding insulin spikes” and focus instead on things like whether the food feels heavy in your stomach when you run or gives you GI distress or otherwise doesn’t make you feel good. If it doesn’t, try different food and try different timing.

4. Race start and race strategy

You should definitely have a plan for how you run your race. In my case, because I’m a run/walker, I think about which set of intervals I will start at (likely 30:90, meaning 30s run and 90s walk, because that’s also how I train and helps me achieve my easy effort and easy paces). My goal is to start easy and limit excitement. Since I’m solo running, I don’t get swept up in other people running and racing. But, I always find the start and the first mile to be hard. So my strategy instead is to start, make sure all my intervals and run trackers are turned on; my electrolyte and fuel timers are set; and that I get my audiobook or podcast going. I troubleshoot any of these as needed on the walk intervals as I get going. I specifically try not to think about pace, especially the first half mile, nor how it’s feeling so I don’t catastrophize. I know the first 0.75 miles or so always feels pretty rough, so I aim to do no foreshadowing of how anything else is going to feel.

For most people running organized races, it helps to have studied the course maps and elevation profiles. Learn the course by heart, in terms of knowing how many miles to each aid station and what the elevation profile is like, and what your strategy is for each section. This means having a pace plan from the start and if you are going way too fast (due to excitement and other people around you), switching to walk breaks to help moderate your pace if you can’t slow your run pace down on its own. It also might help to not only have a pace plan but to also put time estimates on aid stations or check points. Use any extra time – especially if you are far ahead – to address any issues popping up (chafing, blisters or hot spots on your feet, etc.). Don’t start foreshadowing and forecasting that you can hold this too-fast pace through the whole race. You likely can’t (physically), and skipping the plan to stop and address issues will also doubly backfire later.

Even though I’m not running an organized race, this is still something I struggle with. I’m setting the goal to stop for bathroom breaks or shoe re-lacing or hotspot fixing in the first out and back “lap”, recognizing that it will help get my average time here to slow down a bit and keep me from powering through it too hard based on initial excitement. My goal is to make sure I don’t skimp on self-support (e.g. foot care or re-applying anti-chafe) by folding that it in to my goal pacing.

In general, though, because I’m running a 7 “lap” course, I focus on each lap. And only that lap. I’m running known out-and-back or triangle shaped “loops” that I know and love, so I can treat the first out-and-back like a long extra-easy run and settle in to watch landmarks while I listen to my audiobook and focus solely on managing effort. When I get back after the first loop and refill my vest, I then can think about the lap that I’m on (13 miles next, a much shorter loop). When I’m back, then I think about the next out and back (about 16 miles). And so on. My goal is to never think about how much time or distance is left. I’m not good at “running the mile I’m in”, as people often advise, but I am fairly good at focusing on a sub-component and the process overall. So focusing on each lap, and knowing there are 7 laps of varying lengths, helps me compartmentalize the experience. I’ll run ¼ of the first out and back in the dark and transition into the daylight; the second lap should also be during the day; then I’ll transition to my night gear for the third lap and be in the dark on the 4th, 5th, and 6th lap. I don’t have aid stations or elevation changes to really break up the course, but since I know the course and all the landmarks well, even with the variable distance “laps”, that aids me in knowing what to watch for and keep moving toward, even if I transition to a walk or get off track pace-wise from problem solving and am trying to re-orient myself again afterward.

It’s good to think about what supplies you’ll carry versus what you will have access to at aid stations, what you have in drop bags, and what your crew will have. I generally carry most of my needed first-aid/don’t feel good supplies on me: anti-chafing, kinesio tape for blisters or muscles, anti-nausea medication, etc. But I have a set of supplies prepped and ready for my husband (who is my crew) to bring to me if needed. I won’t have aid stations, so I think about my planned re-fuel stops as aid stations where he’ll primarily be. If something gets really bad, though, he can bike out to meet me. In some races you may have crew access to the trails wherever you need them; in other races, they are not allowed or able to access you outside designated points. Plan and carry supplies accordingly.

And, plan for your crew how to help you and how you’ll communicate with them. I will have cell service on my run, so I plan to text my husband to give him updates (in addition, he can geo-track my phone’s location) of when I’m on or off the last predicted pace to a refuel stop; what I want him to bring (e.g. the 2 hot/fresh food items, or any extra supplies from my laid-out stash); and how it’s going. We have practiced on training runs for him to grab my vest and refill ice and water, fuel, electrolytes/enzymes/eye drops, then bring it back to me (biking) or when I re-pass him after I’ve turned around and come back to the spot where he is per my course plan. But I also expect him, as crew, to also get tired and mentally fatigued, so I’ve made a checklist that he will use to make sure he completes the steps every lap. There’s also a checklist for day to night transition and night to day transition. This is in the same online document as my expert list of supplies and strategies to troubleshoot every issues, so he doesn’t have to guess what the good options are for fixing blisters or low sodium or whatever the issue may be. He runs, but he doesn’t do ultra runs, and regardless everyone is different in terms of what works for them and especially what works for them at different stages of an ultra; thus, having this crew guide or checklist or supply/strategy “cheatsheet” is a benefit, especially as both he and I get more and more tired through the night.

My strategy also includes making sure my devices stay powered. I always carry a small battery and a charging cord for my phone, and will keep my phone power topped off. This is because I use it for run tracking; geolocation for my crew (husband); fuel/electrolyte reminders; fuel tracking via my spreadsheet; and it is the “receiver” for my CGM so I know what my blood sugars are. Thus, it’s a mission-critical device and I always like to keep it charged. I will also grab a watch charger from my husband after a certain number of laps to top off the charge on my watch 1-2x, based on how it’s battery is doing. He’ll replace the battery in my vest each time after I’ve used it (we’ve got 2-3 small batteries for this purpose so he can take one home and re-charge it while I’m using the other, plus another backup). My phone then also serves as an emergency back-up light if my other two lights fail at night.

Speaking of lights and night gear, have a plan for when and how you’ll transition to night gear. Because I’m running a solo/DIY race and I’m not experienced at running at night (although I’ll do a run or two in training to practice the transition and my gear), I’m actually choosing to start my run at 6am so I run about 1.5-2 hours in the dark at the start of my race. Why? My husband doesn’t believe it’s necessary and is still arguing with me about it, but my strategy is intentional. I want to start the run in my lights and night gear and practice running in the dark again so that I can see if I need to tweak or adjust it for later that night around 6pm when I need to run in the dark again. This gives me one more practice round and mentally will help me – or at least, that’s the goal – know what it’s like to run in the dark. Given that I’ll run in the dark for 14h overnight, I don’t want to pick up my lights and take off and be 6-8 miles down trail from my husband and my backup gear if I realize something isn’t working well. I know I’ll be prone to just sticking it out for the entire lap; this way, I get a mini, 1.5h test of the gear on the same day and that way when I do a 3-5 hour first lap in the dark that evening, it’ll be slightly more likely to go smoothly and I’ll take all the smoothing I can get for my first 100M and my first all night and overnight run!

My other strategy involves self-care in the sense of regular medications that I need. Of course, I’ll be managing my blood sugars and insulin very carefully all day throughout (often thinking about it every 10-15 minutes to make sure everything is on track). But I also take allergy medication twice a day at morning and night, as well as a thyroid medication at night. So I have set reminders on my husband’s calendar to make sure he brings out my bags of night medication (e.g. allergy and thyroid) and in the morning (allergy) medication to make it less likely that I’ll forget to take them. Thankfully if I mess this up and am super delayed or forget to take them, it won’t derail my race/run much, but I definitely will feel not taking my allergy medication within hours so that will also help me remember to take my thyroid evening medication, too.

Another self-care strategy is around keeping my eyes hydrated with eye drops on a regular basis. In October 2021 I started to have really dry, gritty eyes and went to my eye doctor and was diagnosed with…dry, gritty eyes. Helpful! But, sarcasm aside (I love my eye doctor), I got eye gel to use before bedtime and eye drops to use throughout the day. Then in August 2022 I realized I had subclinical hyperthyroidism from Graves’ disease, which is an autoimmune disease (to go with type 1 diabetes, celiac disease, and exocrine pancreatic insufficiency) that causes eye issues. So! My dry gritty eyes were a precursor to my thyroid level changes. At any rate, learning how and when to use eye drops has become routine and I know how helpful it is to keep my eyes lubricated. I use preservative-free eye drops, not because the preservatives bother my eyes but because they come in miniature vials that are very easy to put in your pocket. Supposedly they are designed to be single use, but they usually contain enough lubrication for 2-3 rounds of drops for both eyes. So I twist off the lid, drop in both eyes, put the lid back on, and stuff it back in my pocket. I have set reminders on my calendar during the run to do this every few hours in case I forget, but I have also put vials in each lap bag (along with electrolytes and enzymes) and this presence of new eye drop mini-vials will help remind me (hopefully) to stay on top of eye lubrication.

Keeping my eyes from getting dry will hopefully help me be able to wear my contacts longer, because I usually take them out at night. But, I also will have my husband ready with my contact case and contact solution to take them out; then I will switch to my glasses or run without them (because I don’t need to see far or read signs off in the distance) for some period of hours, while still using the eye drops to keep them happy.

I’m fairly nervous about my eyes being an issue, since I’ve never run this long or all night. This was exacerbated by reading race recaps where folks talked about losing their vision! Yikes! I read a little bit more and realized they’re talking about corneal edema, where there is temporary swelling in the edema that makes your retinas visually look cloudy (if someone else looks at your eye). It usually goes away when people stop running after a few hours or day. But given my eye issues, before I had realized I was dealing with eye stuff related to Graves’ disease and thyroid stuff, I was concerned that my tendency to dry/gritty eyes would make me at higher risk of this, even though it seems like only 1-2% of 100M finishers ever deal with this. But, like everything else, I decided to have a strategy for this. I’ll seek to prevent it with regular lubrication and if it’s cold and windy, using my glasses (in lieu of contacts) or clear biker glasses or sunglasses to help protect my eyes from irritation and drying out further. But if it does happen, I’m using the advice from this post and bought a small vial of 5% hypertonic eye drops to use and try. (I had a regular annual eye doctor appointment a month prior, so I checked with my eye doctor about this. She had never heard of it and consulted a cornea specialist who had also not heard of it, which helps confirm that it’s pretty rare! Although they admitted they don’t get a lot of endurance athletes, looked it up on PubMed like I had, and agreed that if it happens to try the 5% hypertonic eye drops. Note that contact wearers want to take the contacts out before using these drops.) If I start to have vision issues; and I have the clear visual symptoms of this (according to Scott’s assessment of looking at my eyeballs); I’ll try the eye drops and ideally they’ll help. Since this is a known issue, if I still have some vision and can run safely (given my 6 foot wide paved trail in a safe location with no navigation required); I will likely try to continue – again based on discussion and advice with my doctor. But having a plan for this is much better than suddenly having vision issues in the ultra and feeling like I need to abort, when it might be ok to continue running (again on advice from my doctor).

Another strategy is thinking about how I’ll use caffeine. I usually drink caffeine up until noon, then switch to caffeine-free diet soda (and more water) in the afternoon and evening. I’ll drink a diet Mtn Dew when I wake up with my breakfast, but only one, and I will aim not to drink any throughout the day and save them for after midnight, when I’ll have been running for 18+ hours and have spent 6 hours in the dark. That way I have a “pick me up” to look forward to, both in terms of the taste/flavor of diet Mtn Dew, which I love, and some caffeine. There’s some suggestion that weaning off caffeine in the weeks prior to the race would make this a more effective strategy; but for me I think removing the joy of diet Mtn Dew would not be a net benefit. I’m also not convinced that I know what amount of caffeine is needed for an overnight boost, nor that I can test this reliably enough to have a solid evidence-based strategy here. So instead, I’m likely going for the mental boost of the taste change and the placebo effect of thinking the caffeine is helping. I have, however, tested drinking a diet Mtn Dew during a long run in the morning; so I do know that my body is ok taking it in.

This is yet another example of how I’m trying to remove decision-making during the race by pre-planning wherever possible for decisions like when to take caffeine or not; what to eat when; etc. I have laid out pacing sheets for a wide variety of run paces – so wide that the fastest pace (if all goes amazingly well) would have me finishing 8 hours faster than the slowest pace I have charted out. But the reason this matters is because I’m using the slowest time to estimate how much fuel I need to have prepared, then preparing more as backups (see more detail in the nutrition section). I created my overall fuel list then started putting in estimates of how many of each I would be willing to consume, also factoring in palate fatigue and texture fatigue and not wanting to chew or put ‘hard’ things (like Fritos) into my mouth in the later hours of my run. I balanced all of these variables and came up with 6 max servings of my chili cheese Fritos, most of which will be consumed in the earlier hours; 6 max servings of a few other routine things I can eat in most situations, then smaller counts (eg 1-4) of other things like the hot/home food that my husband will bring out in addition to the shelf-stable food. Once I had my overall counts totaling enough fuel for the slowest hour estimate and the number of servings; I then made a lap-by-lap list of what I wanted to eat when. I’m going to prepare these bags with the numbers I need per lap based on the timing (e.g. 10 snacks for the slowest pace estimated for my longest lap in between refuels, of which 8 are shelf stable and 2 will be added based on the sticky note reminder for the fresh/home options). Each of these lap bags will also include the requisite number of electrolyte pills I need, based on similar estimates from my “slow” paces, and the enzymes I need (because I have exocrine pancreatic insufficiency and need these to actually digest the fuel I consume), plus new eye drops. The point of this strategy is to remove decision making for both me and my husband: we don’t need to figure out how many enzymes or electrolytes I have “left” from the last lap (because I am off my fueling plan or more likely because I packed extra for each); instead, he can simply pull out all the trash, old enzyme/electrolyte bags, and replace with the new fuel, electrolyte, and enzymes along with my water/ice refill.

You may not have the complexity of my situation (type 1 diabetes, celiac, exocrine pancreatic insufficiency) influencing your fueling strategy and choices and how you’ll deal with fuel on the run. But, you might want to consider similarly planning your fuel. You may need to adapt your strategy based on how you’re feeling and what options you have in your pack, drop bag, with crew, or at an aid station, but you can plan for options to address issues of fatigue, palate/texture fatigue, etc. That, essentially, is what I have done.

Finally, I also consider a safety strategy part of my important race planning. I wear a watch that will generate an SOS alert and call emergency services if I fall during a run. I have the ability to press and hold a button on my watch or my phone to similarly generate an emergency services call. My location is tracked by my husband (and my mom from afar); and my husband also has access to my CGM for blood glucose tracking. He’ll have extra alerts and alarms set at different thresholds than we typically do for glucose levels. Finally, we’ve also created what I call the “DanaWatch” plan/squad, which is 3 people who will be texting me periodically from midnight to 9am my time, which is the overnight hours when Scott will be intermittently sleeping for 1-2 hour snatches in between refueling me. The plan is for my friend in the UK to text me every half hour and watch for a response that I’ll generate from my watch – probably a simple thumbs up emoji or tapping one of the auto-generated responses like “thanks” or “hi” or “I’m good”. After a few hours, a friend on the east coast will take over. Then my mom in central time zone after she wakes up will start texting. Nothing fancy, but the point is that they have ensured I’m still moving and ok. If I don’t respond within 5 minutes, they’ll call me; if I don’t pick up the phone, they’ll call Scott. This means that there wouldn’t be more than about 30 minutes where I’m not actively being “watched” virtually in case I get swooped by an owl, fall down and hit my head and am too disoriented to call for help (or some other very rare situation). I don’t expect that will happen; but I also think I’ll appreciate the “company” since I’m again, running a solo, DIY race where there aren’t aid stations, other runners, and other crew out and about to cheer me on. It’ll also help my husband sleep better/feel better, so any of those reasons are worth this strategy!

Post-race strategy

Like pre-race strategy, post-race strategy and planning is also critical for me. Once I cross the finish “line” and stop, I get cold and start to feel being wet (from sweat or rain) very quickly. My feet and everything hurt even more. I am absolutely not hungry despite knowing I need to re-fuel. But later I am ravenously hungry like a switch has shifted. So I plan accordingly.

First up, gear change. I want to change into dry clothes. I remind my husband to remind me that yes, despite the pain/hassle of getting out of a wet sports bra and changing it, I’ll regret not changing out of it in addition to changing my shirt. Sometimes, if we are getting in the car to drive home, I quickly swap to a dry shirt and then take the sports bra off under my shirt and just leave it off. No need for gymnastics to put another one on if I am just riding in the car. Same with shoes: once I take my sneakers off, my feet will not want to go back in sneakers. Definitely not the same sweaty, dirty shoes I was running  in, but also not cleaner and even bigger shoes. Instead, I prefer sandals/arch support flip flops. I have those, compression sleeves, and my clean dry clothes ready to go. I learned after my first trail marathon how good a washcloth feels for rubbing off sweat and dirt, so I also have a washcloth. It works for removing masses of mud before you get in the car, too. Or if you’re not muddy and hot and sweaty, pouring some cool water on it and washing your face feels heavenly.

Next up is fueling. When running an organized race, I don’t want to eat any of the race food, even if I can have it. (By “can have it” I mean that it’s safely gluten free with no cross-contamination risk, since I have celiac disease.) Usually I can’t have it, and I plan accordingly to bring food that is not the same food I’ve been eating throughout my ultra (because I have palate fatigue). I don’t want to eat as soon as I stop running, but usually after changing in the car and driving off, my body switches into “you’re safe” mode and wants to start refueling. Make sure you have all your food in the seat with you so you don’t have to stop and dig it out; or worse, have to try to twist around or reach for it (because you won’t want to do that most likely).

And again, you may have palate fatigue or similar (or it may disappear as soon as you are done), so having a few good options will be useful.

I also try to get enough groceries and prepare food for the following several days, too, when I’ll still be hungrier and making up for burned energy. My motivation to cook/prepare/put together food will be low, so having a stocked fridge and freezer with easy to prepare food is important.

Also, you may not be driving home from your race (or being driven home), so make sure to plan your logistics accordingly. Can you get to the airport that same day? Should you? Do you want to? And the next day? Is it safe to fly in your physical state? What different supplies do you need for flying that might be different (due to security regulations around liquid etc) than you would if you were driving home? Do you have enough snacks/food for the travel days following your run?

Training strategy

Oh, and yes, you have to physically train for your ultra. I am by no means a coach or an expert ultra runner. I am a solid, places-from-last back-of-the-pack runner who is a consistent run/walker. So get or make a training plan (Heather Hart has some great free ones for various distances). And stick to it. Except for when you don’t stick to it.

Wait, what?

You set your training strategy for “if all goes well”, but also build in flexibility and extra time for when things don’t go well. Like wildfire smoke season making it unsafe to run outside for a few days or weeks. Or you break your toe and spend 4 weeks not weight bearing. Or you have a lot of life stress, child or parental care, job stress, or any number of things. All this stress impacts training. Give yourself grace and be prepared to be flexible.

I have a hard time with this; I like my spreadsheets and my plans. But wildfire smoke and a broken toe were part of my 2022 ultra training experience this year, and I had to adjust training (and race plans) accordingly. At some point, you have to make the go/no-go decision about whether you’re going to run your race.

Think about what the “ideal training” is. Think about what is the “minimum training” to complete your event safety. If you’re somewhere in between, it’s going to be mental training and planning that can make the difference. At some point, if you’re above ‘minimum’ training you can decide to run even if your training isn’t ideal. Remember, it probably won’t be ideal and it isn’t for a lot of people. But per the mental training section and the wisdom I’ve gained from a lot of ultra runners…the most important factor might be deciding to do it. If you decide to, barring injury during the race or an accident, you will. If you decide mid-race you can’t or don’t want to, likely you won’t.

I think one thing I observe people not training is their walking strategy. Mine is baked in, because all my training short and long runs are intervals of run/walk. Many folks talk about walking hills or walking X minutes per Y minutes or Z miles. If that’s the plan for your race, train it during long runs. Walk hills or powerwalk or hike hills during runs or at the ends of runs. Practice a slow walk mixed in or a faster more efficient power walk. This will help build different muscles and help you maintain more efficient form (and speed) when you shift to it during the race, and help you go longer.

Similarly, practice with your vest/pack/handheld and other hydration gear. Practice with a similar stuffed and weighted pack. Practice with your head lamp. Do a run early in the morning as it transitions from dark to light; do a run into the evening as it transitions from light to dark to get used to your gear; practice troubleshooting it; and to improve your strategy for these transitions. If it’s wildfiresmoke season where you live, practice running masked as well. (On my last long run, I wore my mask for the full 8 hour run because air quality was so yucky.)

Also train and practice with your crew, if possible. Especially things like helping them tape or lubricate, tying your shoes, helping you put your pack on, them packing your pack/vest with supplies, etc. Any of these steps can be practiced during a training run so you and they can figure out what questions and assumptions you each have, and to build the crew checklist and instructions.

In my case, I’ve trained with my husband on refilling my ice and water in my pack during several training runs and previous races. We haven’t trained yet on him re-packing my (new) vest, though, so that’s on our list to practice on runs heading into my 100M. We did practice one run where I needed him to pick me up at a trail construction closure and drive me to the other side, with him bringing me a fresh/hot home-prepared fuel option. It worked well to a degree; I had a ¼ ham and cheese quesadilla slice in the microwave and had told him how to microwave it, which I had factored in cooling time for when he would be driving it to me before I would eat it. But he also tried to optimize and then put it in our car-based portable food warmer, which doesn’t do well with plastic bags (it needs a tupperware container) in general and was way too much heat. So it was scalding hot when I got in the car! Oops. Lesson learned. That was maybe unique to the car scenario but we will also test and practice the other food warming up options to make sure he doesn’t accidentally re-optimize where I’ve already optimized the food process; and make sure I have in fact optimally optimized the food strategy for each item.

Conclusion

Wow, that’s a lot of planning and strategy now that I’ve written it all out. Which makes sense, because I’ve been thinking about all these things for months and iterating on my strategies and plans. Hopefully, it’ll pay off and help immensely with making my 100M experience more smooth (note that I doubt any 100M would be easy/easier but I hope for “smoother”!) than it otherwise would be.

In summary, I pre-plan mentally for how it’ll feel running; I attempt to solve as many problems in advance as I can and prep supplies for fixing problems; I test, plan, and practice my fueling as much as possible; I aim to carefully pace effort as well as speed during my run; I break my run up into mental chunks so I am not dwelling on what’s to come but focusing on running the current segment; I try to minimize decision fatigue during and after the race by pre-doing anything I can and pre-supplying myself to make it easier; and of course, I train for months to prepare physically as best as possible while realizing that my training might not ever be ideal but that I can still safely attempt to run 100 miles.

PS – if there are any strategies, tips, or approaches you take to ultrarunning, especially 100 miles or more distance-wise, I’d love to hear them! Please share them in the comments or link to any posts you’ve written. I’m still learning and likely will always be evolving my strategies!

Note: I wrote this post before my 100 mile attempt. I ended up completing 82 miles and happily choosing to stop, knowing that I could physically keep going. Looking back at the above and reflecting on my experiences, I didn’t have a single challenge or experience that I wasn’t prepared to deal with or couldn’t deal with, thanks to all of the above work. So I’m thrilled and proud of my 82 mile experience!

Wondering about the “how” rather than the “why” of autoimmune conditions

I’ve been thinking a lot about stigma, per a previous post of mine, and how I generally react to, learn about, and figure out how to deal with new chronic diseases.

I’ve observed a pattern in my experiences. When I suspect an issue, I begin with research. I read medical literature to find out the basics of what is known. I read a high volume of material, over a range of years, to see what is known and the general “ground truth” about what has stayed consistent over the years and where things might have changed. This is true for looking into causal mechanisms as well as diagnosis and then more importantly to me, management/treatment.

I went down a new rabbit hole of research and most articles were publicly accessible

A lot of times with autoimmune related diseases…the causal mechanism is unknown. There are correlations, there are known risk factors, but there’s not always a clear answer of why things happen.

I realize that I am lucky that my first “thing” (type 1 diabetes) was known to be an autoimmune condition, and that probably has framed my response to celiac disease (6 years later); exocrine pancreatic insufficiency (19+ years after diabetes); and now Graves’ disease (19+ years after diabetes). Why do I think that is lucky? Because when I’m diagnosed with an autoimmune condition, it’s not a surprise that it IS an autoimmune condition. When you have a nicely overactive immune system, it interferes with how your body is managing things. In type 1 diabetes, it eventually makes it so the beta cells in your pancreas no longer produce insulin. In celiac, it makes it so the body has an immune reaction to gluten, and the villi in your small intestine freak out at the microscopic, crumb-level presence of gluten (and if you keep eating gluten, can cause all sorts of damage). In exocrine pancreatic insufficiency, there is possibly either atrophy as a result of the pancreas not producing insulin or other immune-related responses – or similar theories related to EPI and celiac in terms of immune responses. It’s not clear ‘why’ or which mechanism (celiac, T1D, or autoimmune in general) caused my EPI, and not knowing that doesn’t bother me, because it’s clearly linked to autoimmune shenanigans. Now with Graves’ disease, I also know that low TSH and increased thyroid antibodies are causing subclinical hyperthyroidism symptoms (such as occasional minor tremor, increased resting HR, among others) and Graves’ ophthalmology symptoms as a result of the thyroid antibodies. The low TSH and increased thyroid antibodies are a result of my immune system deciding to poke at my thyroid.

All this to say…I typically wonder less about “why” I have gotten these things, in part because the “why” doesn’t change “what” to do; I simply keep gathering new data points that I have an overactive immune system that gives me autoimmune stuff to deal with.

I have contrasted this with a lot of posts I observe in some of the online EPI groups I am a part of. Many people get diagnosed with EPI as a result of ongoing GI issues, which may or may not be related to other conditions (like IBS, which is often a catch-all for GI issues). But there’s a lot of posts wondering “why” they’ve gotten it, seemingly out of the blue.

When I do my initial research/learning on a new autoimmune thing, as I mentioned I do look for causal mechanisms to see what is known or not known. But that’s primarily, I think, to rule out if there’s anything else “new” going on in my body that this mechanism would inform me about. But 3/3 times (following type 1 diabetes, where I first learned about autoimmune conditions), it’s primarily confirmed that I have autoimmune things due to a kick-ass overactive immune system.

What I’ve realized that I often focus on, and most others do not, is what comes AFTER diagnosis. It’s the management (or treatment) of, and living with, these conditions that I want to know more about.

And sadly, especially in the latest two experiences (exocrine pancreatic insufficiency and Graves’ disease), there is not enough known about management and optimization of dealing with these conditions.

I’ve previously documented and written quite a bit (see a summary of all my posts here) about EPI, including my frustrations about “titrating” or getting the dose right for the enzymes I need to take every single time I eat something. This is part of the “management” gap I find in research and medical knowledge. It seems like clinicians and researchers spend a lot of time on the “why” and the diagnosis/starting point of telling someone they have a condition. But there is way less research about “how” to live and optimally manage these things.

My fellow patients (people with lived experiences) are probably saying “yeah, duh, and that’s the power of social media and patient advocacy groups to share knowledge”. I agree. I say that a lot, too. But one of the reasons these online social media groups are so powerful in sharing knowledge is because of the black hole or vacuum or utter absence of research in this space.

And it’s frustrating! Social media can be super powerful because you can learn about many n=1 experiences. If you’re like me, you analyze the patterns to see what might be reproducible and what is worth experimenting in my own n=1. But often, this knowledge stays in the real world. It is not routinely funded, studied, operationalized, and translated in systematic ways back to healthcare providers. When patients are diagnosed, they’re often told the “what” and occasionally the “why” (if it exists), but left to sometimes fall through the cracks in the “how” of optimally managing the new condition.

(I know, I know. I’m working on that, in diabetes and EPI, and I know dozens of friends, both people with lived experiences and researchers who ARE working on this, from diabetes to brain tumors to Parkinson’s and Alzheimer’s and beyond. And while we are moving the needles here, and making a difference, I’m wanting to highlight the bigger issue to those who haven’t previously been exposed to the issues that cause the gaps we are trying to fill!)

In my newest case of Graves’ disease, it presented with subclinical hyperthyroidism. As I wrote here, that for me means the lower TSH and higher thyroid antibodies but in range T3 and T4. In discussion with my physician, we decided to try an antithyroid drug, to try to lower the antibody levels, because the antibody levels are what cause the related eye symptoms (and they’re quite bothersome). The other primary symptom I have is higher resting HR, which is also really annoying, so I’m also hoping it helps with that, too. But the game plan was to start taking this medication every day; and get follow-up labs in about 2 months, because it takes ~6 weeks to see the change in thyroid levels.

Let me tell you, that’s a long time. I get that the medication works not on stored thyroid levels; thus, it impacts the new production only, and that’s why it takes 6 weeks to see it in the labs because that’s how long it takes to cycle through the stored thyroid stuff in your body.

My hope was that within 2-3 weeks I would see a change in my resting HR levels. I wasn’t sure what else to expect, and whether I’d see any other changes.

But I did.

It was in the course of DAYS, not weeks. It was really surprising! I immediately started to see a change in my resting HR (across two different wearable devices; a ring and a watch). Within a week, my phone’s health flagged it as a “trend”, too, and pinpointed the day (which it didn’t know) that I had started the new medication based on the change in the trending HR values.

Additionally, some of my eye symptoms went away. Prior to commencing the new medication, I would wake up and my eyes would hurt. Lubricating them (with eye drops throughout the day and gel before bed) helped some, but didn’t really fix the problem. I also had pretty significant red, patchy spots around the outside corner of one of my eyes, and eyelid swelling that would push on my eyeball. 4 days into the new medication, I had my first morning where I woke up without my eyes hurting. The next day it returned, and then I had two days without eye pain. Then I had 3-4 days with the painful eyes. Then….now I’m going on 2 weeks without the eye pain?! Meanwhile, I’m also tracking the eye swelling. It went down to match the eye pain going away. But it comes back periodically. Recently, I commented to Scott that I was starting to observe the pattern that the red/patchy skin at the corner and under my right eye would appear; then the next day the swelling of and above the eyelid would return. After 1-2 days of swelling, it would disappear. Because I’ve been tracking various symptoms, I looked at my data the other day and saw that it’s almost a 6-7 day pattern.

Interesting!

Again, the eye stuff is a result of antibody levels. So now I am curious about the production of antibodies and their timeline, and how that differs from TSH and thyroid hormones, and how they’re impacted with this drug.

None of that is information that is easy to get, so I’m deep in the medical literature trying again to find out what is known, whether this type of pattern is known; if it’s common; or if this level of data, like my within-days impact to resting HR change is new information.

Most of the research, sadly, seems to be on pre-diagnosis or what happens if you diagnose someone but not give them medication in hyperthyroid. For example, I found this systematic review on HRV and hyperthyroid and got excited, expecting to learn things that I could use, but found they explicitly removed the 3 studies that involved treating hyperthyroidism and are only studying what happens when you don’t treat it.

Sigh.

This is the type of gap that is so frustrating, as a patient or person who’s living with this. It’s the gap I see in EPI, where little is known on optimal titration and people don’t get prescribed enough enzymes and aren’t taught how to match their dosing to what they are eating, the way we are taught in diabetes to match our insulin dosing to what we’re eating.

And it matters! I’m working on writing up data from a community survey of people with EPI, many of whom shared that they don’t feel like they have their enzyme dosing well matched to what they are eating, in some cases 5+ years after their diagnosis. That’s appalling, to me. Many people with EPI and other conditions like this fall through the cracks with their doctors because there’s no plan or discussion on what managing optimally looks like; what to change if it’s not optimal for a person; and what to do or who to talk to if they need help managing.

Thankfully in diabetes, most people are supported and taught that it’s not “just” a shot of insulin, but there are more variables that need tracking and managing in order to optimize wellbeing and glucose levels when living with diabetes. But it took decades to get there in diabetes, I think.

What would it be like if more chronic diseases, like EPI and Graves’ disease (or any other hyper/hypothyroid-related diseases), also had this type of understanding across the majority of healthcare providers who treated and supported managing these conditions?

How much better would and could people feel? How much more energy would they have to live their lives, work, play with their families and friends? How much more would they thrive, instead of just surviving?

That’s what I wonder.

Wondering "how" rather than "why" of autimmune conditions, by @DanaMLewis from DIYPS.org

Graves’ Disease, Subclinical Hyperthyroidism, and Everything I Have Learned About It (So Far)

TLDR: I have newly diagnosed Graves’ Disease, I have associated eye stuff (called “Graves’ orbitopathy” or “Graves’ ophthalmopathy” or “thyroid eye disease”), subclinical hyperthyroidism, and a new learning curve. Below is what I’ve learned so far and what I’m still exploring.

As a person with type 1 diabetes (T1D) – which is an autoimmune disease – I am screened yearly for various high-risk related conditions. For example, celiac disease and thyroid issues, because those are fairly common in people with type 1 diabetes. I already have celiac disease (developed ~6 years after I developed T1D), but we have continued to screen every year in my annual blood work for thyroid markers, usually by screening T4 and TSH. Occasionally, T3 and/or TPO antibodies are also screened.

I remember vividly the chortle that my prior endocrinologist made after we diagnosed my celiac disease in college, probably in response to my comment about being frustrated of having “another” thing to deal with in addition to T1D. He chortled and said something like “once you have one (autoimmune thing), you’re likely to have two. Once you have two, you’ll be likely to have three.”

I didn’t like it at the time, and I don’t like it now. However, he’s not wrong. When your immune system has a little extra kick in it and you develop one autoimmune disease, the rates of having another autoimmune thing are increased. Thus, the typical yearly screening in T1D for celiac & thyroid.

I went 6 years between T1D and celiac, then almost 12-13 years to discover I now have exocrine pancreatic insufficiency (EPI). That’s not necessarily an autoimmune thing but may be a side effect of long-term T1D. Regardless, I was still thankful for the long period of time between T1D and celiac, then T1D+celiac and EPI. I was assuming that something else was coming eventually, but that I’d likely have a few years before the shoe dropped.

Nope.

I wasn’t terribly surprised when I scheduled my annual endocrinology appointment and did my annual blood work to find that one of my thyroid values was off. Specifically, my TSH (thyroid stimulating hormone) was low / below normal range. However, my T4 was smack dab in the middle of normal range. I got my blood work back Tuesday and waited for my virtual appointment on Friday to discuss in detail with my endocrinologist.

Since I’m me, I was curious about the interplay between normal thyroid levels (T4, and I suspected my T3 was likely still in range) but a low TSH value. What did that mean? General consensus seems to define this as “subclinical hyperthyroidism”. It’s not always treated, unless you are older (>65), have osteoporosis or heart disease, or TSH levels are <0.1.

I’m <65, don’t (as far as I know) have osteoporosis or heart disease, and my TSH levels are between 0.1 and 0.4, which is the low end of the normal range. So general treatment guidelines (see this example from the AAFP) suggest treatment isn’t necessarily warranted.

However…there’s more information that factors into the decision making. First, I had my last annual eye exam in October. All was well. Yet in November, I developed really gritty, dry eyes and went in for an appointment. I was diagnosed with dry eyes (gee, thanks!) and recommended to use gel drops at night before bed and regular eye drops during the day as needed. I did end up needing eye drops several times every day.

Then at the end of December or early January, we realized I had exocrine pancreatic insufficiency (EPI). I had been wondering if my dry eyes was related to the lack of digestion and absorption of nutrients, which also influences how my body uses the water content from food. It did seem to get a little better in the following months, because while I still needed the eye gel at night, I eventually moved to several days a week where I didn’t seem to need the eye drops during the day – yay!

However, in February and early March, I started to physically notice a shift in my resting overnight heart rate (HR). My Pebble 2+ HR watch and my Oura ring, both of which measure HR and heart rate variability (HRV), confirmed that both metrics were getting worse. I had a slowly increasing overnight HR and associated decrease in HRV. I am used to fluctuations, because the intensity of my ultrarunning can also influence HR the next day as a signal for whether my body has recovered yet or not. But instead of a day or two of increased numbers, I had an increasing trend line over several weeks, and it started to physically become bothersome. I actually raised the idea of getting my thyroid blood work done early this year, and was about to request the lab work, when after ~6 weeks or so the trend seemed to reverse and things (HR-wise) went back to “normal” for me.

Then I broke my toe in July and the same thing happened, but I chalked it up to sleep disruption from the pain and recovering from the fracture. My HR was continuing to rise even as the pain subsided and my toe was clearly healing. And looking back at my HR data, I can see it actually started to rise at the beginning of July, about two weeks before I broke my toe, so it’s not solely influenced by my broken toe.

As a result of these HR increases (that are noticeable and bothersome because I’m also not sleeping well at night and I physically feel the higher HR during the day), and the ongoing dry/gritty eyes, I suspected that the cause of my “subclinical hyperthyroidism” was Graves’ disease.

I’ve seen estimates that ~30% of people with Graves’ disease have what is called “Graves’ orbitopathy” (and other estimates suggest 20-50%, like this one), so the combination of my ongoing eye symptoms and the low TSH suggested that further lab work assessing various thyroid antibody levels would be able to confirm whether Graves’ disease was the likely source of the subclinical hyperthyroidism.

Therefore, I wasn’t surprised during my virtual visit that my endocrinologist ordered additional labs (repeat of T4 and TSH; adding in T3, TPO antibodies, and TSI (Thyroid Stimulating Immunoglobulin), Thyrotropin Receptor Ab, and Thyroglobulin Ab). Treatment plan, if any, would be based on these results.

I managed to get in that (Friday) afternoon for the repeat lab work, and my results started trickling in by the time I woke up Saturday morning. First, T3, T4, TPO, and TSH came back. T4 was still normal; as I expected, T3 was also normal. TPO antibodies were high, as expected, TSH was still low, as I expected. Saturday night, Thyroglobulin Ab came back high, as expected. Monday, TSI came back high, as expected. Tuesday, my last test result of Thyrotropin Receptor Ab came back, also high as expected.

The summary was: all antibodies high; TSH low; T3/T4 normal.

My endocrinologist messages me Tuesday afternoon confirming mild Graves’ disease with subclinical hyperthyroidism.

The challenge is that I have normal T3/T4 levels. If those were high, we’d treat based on those levels and use those levels coming back into normal range and any change in antibody levels to assess that things were going well.

But the guidelines for subclinical hyperthyroidism don’t really indicate treatment (except on an individual level based on age, other conditions, or undetectable TSH <0.1, as I mentioned).

However, from what I’ve read, the “eye stuff” seems to be driven not by thyroid levels but by the presence of the increased thyroid antibodies. Treatment would possibly bring down the thyroid antibody levels, which might help with the eye disease progression. But not a guarantee. So my doctor left it up to me to decide whether to treat it or not.

Given the ongoing presence of active eye disease (I haven’t been able to wear my contacts for two weeks right now due to swelling/pain in the eyes, plus itching and redness), and the bothersome heart rate feeling, I have decided to try antithyroid medication. I’ll be on a relatively low dose of an “antithyroid” drug, again with the goal of trying to reduce my antibody levels.

This is why I ended up deciding to write this blog post after all: I have not been able to find any clear treatment guidelines for subclinical hyperthyroidism and Graves’ disease with active eye symptoms (from Graves’ orbitopathy). The literature does suggest that treatment to reduce thyroid antibodies even with in-range T3 and T4, targeting a return to normal TSH levels, may be helpful in reducing Graves’ orbitopathy symptoms. This isn’t well known/established enough to have been documented in treatment guidelines, but does seem to occur in many people who are treated.

So hopefully, anyone else with low TSH and high antibodies suggesting Graves’ disease but normal T3 and T4 levels that suggests subclinical hyperthyroidism and also has other symptoms (whether that’s heart rate or other common hyperthyroid symptoms like increased sweating, shaking, heart palpitations, heat intolerance, sleep disturbances) that are bothersome, now have an example of what I chose, given my situation as described above.

I also thought sharing my question list at different stages for my endocrinologist would be helpful. After I saw that I had low TSH and in range T4, and suspected this meant I had subclinical hyperthyroidism from Graves’ disease, given my eye symptoms, the questions I asked my endocrinologist were:

  • What additional lab work did we need to confirm subclinical hyperthyroidism and Graves’ disease as the cause? What additional information or lab work would give us a treatment plan?As expected, he repeated TSH and T4, added T3 and TPO and the other antibody tests described above: TGAb, TRab, TSI. This would confirm subclinical hyperthyroidism and Graves’ as the likely source.

     

  • Do I need treatment, since the guidelines generally don’t suggest treatment with normal T3/T4 and TSH between .1 and .4?Initially he suggested treatment would be an option, and after the repeat and expanded lab work, left it up to my decision. Given my symptoms that are actively bothering me, I’m choosing to try low-dose antithyroid medication.
  • For hyperthyroidism treatment, beta blockers seem to be part of treatment guidelines for managing symptoms in the short-term, since it takes ~6 weeks for antithyroid medication to show up in lab results. Were beta blockers warranted in my case?My endo typically doesn’t like to prescribe beta blockers unless there are extreme symptoms. He gave an example of someone with a T4 (I think) around 10 and extreme visible shaking. He left it up to me, but his opinion was the side effects, such as lethargy, would outweigh the benefits for mild symptoms, so it is better to treat the root cause. I agreed and did not ask for a beta blocker prescription.
  • I also asked if a DEXA scan was warranted to check my bone density.I haven’t had one in over a decade, and celiac and EPI and now Graves’ puts me at possible higher risk of bone density issues. And, since the presence of osteoporosis changes the treatment recommendation for subclinical hyperthyroidism, we agreed it was worth doing. I have it scheduled in a few weeks. My last one over a decade ago was normal.
  • Finally, I asked about my eye care, now that I have a known eye thing (Graves’ orbitopathy). Do I need to get referred to an ophthalmologist, or can I continue to see my existing optometrist for annual eye care (including diabetes eye exam) and contact fittings?My endocrinologist suggested that my optometrist can continue to manage my eye care, unless something changes significantly. Ophthalmologists, based on his response and my research, seem to handle severe eye disease treatments that aren’t likely warranted for me. I’ll probably need supportive eye care (e.g. gel drops, regular eye drops) for now. However, I’m planning to send a note to my eye doctor and flag that I want to talk about Graves’ eye things and a plan for monitoring severity and progression over time, and check whether she’s comfortable supporting me or if she prefers to refer me to someone else. 


After my repeat labs came back, my endocrinologist messaged me to confirm things and ask if I wanted him to send in the prescription as previously discussed. This exchanged answered the additional questions I had at this time:

  • What is the treatment timeline? How soon might I see results?He suggested repeat labs at the 2 month mark. Ideally, we’d see reduced antibody levels and my hope is that my eye symptoms will have also improved and/or I won’t have any additional weeks without being able to wear contacts.

    Given I have a clear impact to my heart rate, I’m hypothesizing that I might see changes to the trend in my heart rate data sooner than 6 weeks – 2 months, so that’ll be interesting to track!

     

  • Side effects?Common side effects with antithyroid drugs are rash/allergic type response, headache, or agranulocytosis. He told me to discontinue and contact the office if I had any of those symptoms.

    He didn’t go into detail, but I’ve read about agranulocytosis and it seems like if you have a fever and strong sore throat, you need to discontinue and probably will have blood work ordered to make sure your white blood cell counts are ok. Don’t google too much on this one as it sounds scary, but it’s also rare – less than 2% of people seem to have this.

     

  • The only question he didn’t answer was whether it makes a difference in efficacy to take the antithyroid drugs at night or in the morning.Probably, the answer is it doesn’t matter, and whatever time you can take it consistently is best. However, I want to optimize and get the best results from taking this, so I’m bummed that there doesn’t seem to be any evidence (let me know if you’ve found anything in medical literature) suggesting how to optimize timing of it. 

So that’s where I am today.

I now have type 1 diabetes, celiac disease, exocrine pancreatic insufficiency, and Graves’ disease (contributing to subclinical hyperthyroidism). It’s possible that we can fix the subclinical hyperthyroidism, and that I won’t need to be on antithyroid medication long-term. However, the data for those of us with Graves’ orbitopathy isn’t super optimistic compared to those without Graves’ eye disease; so I am managing my expectations that managing my thyroid antibody and hormone levels will be an ongoing thing that I get to do along with managing insulin and blood sugars and managing pancreatic enzymes. We’ll see!

New Research on Glycemic Variability Assessment In Exocrine Pancreatic Insufficiency (EPI) and Type 1 Diabetes

I am very excited to share that a new article I wrote was just published, looking at glycemic variability in data from before and after pancreatic enzyme replacement therapy (PERT) was started in someone with type 1 diabetes with newly discovered exocrine pancreatic insufficiency (EPI or PEI).

If you’re not aware of exocrine pancreatic insufficiency, it occurs when the pancreas no longer produces the amount of enzymes necessary to fully digest food. If that occurs, people need supplementary enzymes, known as pancreatic enzyme replacement therapy (PERT), to help them digest their food. (You can read more about EPI here, and I have also written other posts about EPI that you can find at DIYPS.org/EPI.)

But, like MANY medications, when someone with type 1 diabetes or other types of insulin-requiring diabetes starts taking them, there is little to no guidance about whether these medications will change their insulin sensitivity or otherwise impact their blood glucose levels. No guidance, because there are no studies! In part, this may be because of the limited tools available at the time these medications were tested and approved for their current usage. Also this is likely in part because people with diabetes make up a small fraction of the study participants that most of these medications are tested on. If there are any specific studies on the medications in people with diabetes, these studies likely were done before CGM, so little data is available that is actionable.

As a result, the opportunity came up to review someone’s data who happened to have blood glucose data from a continuous glucose monitor (CGM) as well as a log of what was eaten (carbohydrate entries) prior to commencing pancreatic enzyme replacement therapy. The tracking continued after commencing PERT and was expanded to also include fat and protein entries. As a result, there was a useful dataset to compare the impacts of pancreatic enzyme replacement therapy on blood glucose outcomes and specifically, looking at glycemic variability changes!

(You can read an author copy here of the full paper and also see the supplementary material here, and the DOI for the paper is https://doi.org/10.1177/19322968221108414 . Otherwise, below is my summary of what we did and the results!)

In addition to the above background, it’s worth noting that Type 1 diabetes is known to be associated with EPI. In upwards of 40% of people with Type 1 diabetes, elastase levels are lowered, which in other cases is correlated with EPI. However, in T1D, there is some confusion as to whether this is always the case or not. Based on recent discussions with endocrinologists who treat patients with T1D and EPI (and have patients with lowered elastase that they think don’t have EPI), I don’t think there have been enough studies looking at the right things to assess whether people with T1D and lowered elastase levels would benefit from PERT and thus have EPI. More on this in the future!

Because we now have technology such as AID (automated insulin delivery) and CGM, it’s possible to evaluate things beyond simple metrics of “average blood sugar” or “A1c” in response to taking new medications. In this paper, we looked at some basic metrics like average blood sugar and percent time in range (TIR), but we also did quite a few calculations of variables that tell us more about the level of variability in glucose levels, especially in the time frames after meals.

Methods

This person had tracked carb entries through an open source AID system, and so carb entries and BG data were available from before they started PERT. We call this “pre-PERT”, and selected 4 weeks worth of data to exclude major holidays (as diet is known to vary quite a bit during those times). We then compared this to “post-PERT”, the first 4 weeks after the person started PERT. The post-PERT data not only included BGs and carb entries, but also had fat and protein entries as well as PERT data. Each time frame included 13,975 BG data points.

We used a series of open source tools to get the data (Nightscout -> Nightscout Data Transfer Tool -> Open Humans) and process the data (my favorite Unzip-Zip-CSVify-OpenHumans-data.sh script).

All of our code for this paper is open source, too! Check it out here. We analyzed time in range, TIR 70-180, time out of range, TOR >180, time below range, TBR <70 and <54, the number of hyperglycemic excursions >180. We also calculated total daily dose of insulin, average carbohydrate intake, and average carbohydrate entries per day. Then we calculated a series of variability related metrics such as Low Blood Glucose Index (LBGI), High Blood Glucose Index (HBGI), Coefficient of Variation (CV), Standard Deviation (SD), and J_index (which stresses both the importance of the mean level and variability of glycemic levels).

Results

This person already had an above-goal TIR. Standard of care goal for TIR is >70%; before PERT they had 92.12% TIR and after PERT it was 93.70%. Remember, this person is using an open source AID! TBR <54 did not change significantly, TBR <70 decreased slightly, and TOR >180 also decreased slightly.

More noticeably, the total number of unique excursions above 180 dropped from 40 (in the 4 weeks without PERT) to 26 (in 4 weeks when using PERT).

The paper itself has a few more details about average fat, protein, and carb intake and any changes. Total daily insulin was relatively similar, carb intake decreased slightly post-PERT but was trending back upward by the end of the 4 weeks. This is likely an artifact of being careful to adjust to PERT and dose effectively for PERT. The number of meals decreased but the average carb entry per meal increased, too.

What I find really interesting is the assessment we did on variability, overall and looking at specific meal times. The breakfast meal was identical during both time periods, and this is where you can really SEE visible changes pre- and post-PERT. Figure 2 (displayed below), shows the difference in the rate of change frequency. There’s less of the higher rate of changes (red) post-PERT than there is from pre-PERT (blue).

Figure 2 from GV analysis on EPI, showing lower frequency of high rate of change post-PERT

Similarly, figure 3 from the paper shows all glucose data pre- and post-PERT, and you can see the fewer excursions >180 (blue dotted line) in the post-PERT glucose data.

Figure 3 from GV analysis paper on EPI showing lower number of excursions above 180 mg/dL

Table 1 in the paper has all the raw data, and Figure 1 plots the most relevant graphs side by side so you can see pre- and post-PERT before and after after all meals on the left, versus pre and post-PERT before and after breakfast only. Look at TOR >180 and the reduction in post-breakfast levels after PERT! Similarly, HBGI post-PERT after-breakfast is noticeably different than HBGI pre-PERT after-breakfast.

Here’s a look at the HBGI for breakfast only, I’ve highlighted in purple the comparison after breakfast for pre- and post-PERT:

High Blood Glucose Index (HBGI) pre- and post-PERT for breakfast only, showing reduction in post-PERT after breakfast

Discussion

This is a paper looking at n=1 data, but it’s not really about the n=1 here. (See the awesome limitation section for more detail, where I point out it’s n=1, it’s not a clinical study, the person has ‘moderate’ EPI, there wasn’t fat/protein data from pre-PERT, it may not be representative of all people with diabetes with EPI or EPI in general.)

What this paper is about is illustrating the types of analyses that are possible, if only we would capture and analyze the data. There are gaping holes in the scientific knowledge base: unanswered and even unasked questions about what happens to blood glucose with various medications, and this data can help answer them! This data shows minimal changes to TIR but visible and significant changes to post-meal glycemic variability (especially after breakfast!). Someone who had a lower TIR or wasn’t using an open source AID may have more obvious changes in TIR following PERT commencement.

This paper shows several ways we can more easily detect efficacy of new-onset medications, whether it is enzymes for PERT or other commonly used medications for people with diabetes.

For example, we could do a similar study with metformin, looking at early changes in glycemic variability in people newly prescribed metformin. Wouldn’t it be great, as a person with diabetes, to be able to more quickly resolve the uncertainty of “is this even working?!” and not have to suffer through potential side effects for 3-6 months or longer waiting for an A1c lab test to verify whether the metformin is having the intended effects?

Specifically with regards to EPI, it can be hard for some people to tell if PERT “is working”, because they’re asymptomatic, they are relying on lab data for changes in fat soluble vitamin levels (which may take time to change following PERT commencement), etc. It can also be hard to get the dosing “right”, and there is little guidance around titrating in general, and no studies have looked at titration based on macronutrient intake, which is something else that I’m working on. So, having a method such as these types of GV analysis even for a person without diabetes who has newly discovered EPI might be beneficial: GV changes could be an earlier indicator of PERT efficacy and serve as encouragement for individuals with EPI to continue PERT titration and arrive at optimal dosing.

Conclusion

As I wrote in the paper:

It is possible to use glycemic variability to assess changes in glycemic outcomes in response to new-onset medications, such as pancreatic enzyme replacement therapy (PERT) in people with exocrine pancreatic insufficiency (EPI) and insulin-requiring diabetes. More studies should use AID and CGM data to assess changes in glycemic outcomes and variability to add to the knowledge base of how medications affect glucose levels for people with diabetes. Specifically, this n=1 data analysis demonstrates that glycemic variability can be useful for assessing post-PERT response in someone with suspected or newly diagnosed EPI and provide additional data points regarding the efficacy of PERT titration over time.

I’m super excited to continue this work and use all available datasets to help answer more questions about PERT titration and efficacy, changes to glycemic variability, and anything else we can learn. For this study, I collaborated with the phenomenal Arsalan Shahid, who serves as technology solutions lead at CeADAR (Ireland’s Centre for Applied AI at University College Dublin), who helped make this study and paper possible. We’re looking for additional collaborators, though, so feel free to reach out if you are interested in working on similar efforts or any other research studies related to EPI!

A DIY Fuel Enzyme Macronutrient Tracker for Running Ultras (Ultramarathons)

It takes a lot of energy to run ultramarathons (ultras).

To ensure they have enough fuel to complete the run, people usually want to eat X-Y calories per hour, or A-B carbs per hour, while running ultramarathons. It can be hard to know if you’re staying on top of fueling, especially as the hours drag on and your brain gets tired; plus, you can be throwing away your trash as you go so you may not have a pile of wrappers to tell you what you ate.

During training, it may be useful to have a written record of what you did for each run, so you can establish a baseline and work on improving your fueling if that’s something you want to focus on.

For me specifically, I also find it helpful to record what enzyme dosing I am taking, as I have EPI (exocrine pancreatic insufficiency, which you can read more about here) and if I have symptoms it can help me identify where my dosing might have been off from the previous day. It’s not only the amount of enzymes but also the timing that matters, alongside the timing of carbs and insulin, because I have type 1 diabetes, celiac, and EPI to juggle during runs.

Previously, I’ve relied on carb entries to Nightscout (an open source CGM remote monitoring platform which I use for visualizing diabetes data including OpenAPS data) as a record of what I ate, because I know 15g of carbs tracks to a single serving of chili cheese Fritos that are 10g of fat and 2g of protein, and I take one lipase-only and one pancrelipase (multi-enzyme) pill for that; and 21g of carbs is a Honey Stinger Gluten Free Stroopwaffle that is 6g of fat and 1g of protein, and I typically take one lipase-only. You can see from my most recent ultra (a 50k) where I manually took those carb entries and mapped them on to my blood sugar (CGM) graph to visualize what happened in terms of fuel and blood sugar over the course of my ultra.

However, that was “just” a 50k and I’m working toward bigger runs: a 50 mile, maybe a 100k (62 miles), and/or a 100 mile, which means instead of running for 7-8 hours I’ll be running for 12-14 and 24-30(ish) hours! That’s a lot of fuel to need to eat, and to keep track of, and I know from experience my brain starts to get tired of thinking about and eating food around 7 hours. So, I’ll need something better to help me keep track of fuel, enzymes, and electrolytes over the course of longer runs.

I also am planning on being well supported by my “crew” – my husband Scott, who will e-bike around the course of my ultra or my DIY ultra loops and refill my pack with water and fuel. In some cases, with a DIY ultra, he’ll be bringing food from home that I pre-made and he warms up in the microwave.

One of the strategies I want to test is for him to actually hand me the enzymes for the food he’s bringing me. For example, hand me a baggie of mashed potatoes and also hand me the one multi-enzyme (pancrelipase, OTC) pill I need to go with it. That reduces mental effort for me to look up or remember what enzyme amount I take for mashed potatoes; saves me from digging out my baggie of enzymes and having to get the pill out and swallow it, put the baggie away without dropping it, all while juggling the snack in my hands.

He doesn’t necessarily know the counts of enzymes for each fuel (although he could reproduce it, it’s better if I pre-make a spreadsheet library of my fuel options and that helps me both just pick it off a drop down and have an easy reference for him to glance at. He won’t be running 50-100 miles, but he will be waking up every 2-3 hours overnight and that does a number on his brain, too, so it’s easier all around if he can just reference the math I’ve already done!

So, for my purposes: 1) easy tracking of fuel counts for real-time “am I eating according to plan” and 2) retrospective “how did I do overall and should I do something next time” and 3) for EPI and BG analysis (“what should I do differently if I didn’t get the ideal outcome?”), it’s ideal to have a tracking spreadsheet to log my fuel intake.

Here’s what I did to build my ultimate fuel self-tracking self-populating spreadsheet:

First, I created a tab in my spreadsheet as a “Fuel Library”, where I listed out all of my fuel. This ranges from snacks (chili cheese Fritos; Honey Stinger Gluten Free Stroopwaffle; yogurt-covered pretzels, etc.); to fast-acting carbs (e.g. Airhead Minis, Circus Peanuts) that I take for fixing blood sugars; to other snack/treats like chocolate candy bars or cookies; as well as small meals and warm food, such as tomato soup or part of a ham and cheese quesadilla. (All gluten free, since I have celiac. Everything I ever write about is always gluten free!)

After I input the list of snacks, I made columns to input the sodium, calories, fat, protein, and carb counts. I don’t usually care about calories but a lot of recommendations for ultras are calories/hr and carbs/hr. I tend to be lower on the carb side in my regular daily consumption and higher on fat than most people without T1D, so I’m using the calories for ultrarunning comparison to see overall where I’m landing nutrient-wise without fixating on carbs, since I have T1D and what I personally prefer for BG management is likely different than those without T1D.

I also input the goal amount of enzymes. I have three different types of pills: a prescription pancrelipase (I call PERT, which stands for pancreatic enzyme replacement therapy, and when I say PERT I’m referring to the expensive, prescription pancrelipase that’s been tested and studied for safety and efficacy in EPI); an over-the-counter (OTC) lipase-only pill; and an OTC multi-enzyme pancrelipase pill that contains much smaller amounts of all three enzymes (lipase, protease, amylase) than my PERT but hasn’t been tested for safety and efficacy for EPI. So, I have three enzyme columns: Lipase, OTC Pancrelipase, and PERT. For each fuel I calculate which I need (usually one lipase, or a lipase plus a OTC pancrelipase, because these single servings are usually fairly low fat and protein; but for bigger meal-type foods with more protein I may ‘round up’ and choose to take a full PERT, especially if I eat more of it), and input the number in the appropriate column.

Then, I opened another tab on my spreadsheet. I created a row of headers for what I ate (the fuel); time; and then all the macronutrients again. I moved this down to row 3, because I also want to include at the top of the spreadsheet a total of everything for the day.

Example-DIY-Fuel-Enzyme-Tracker-ByDanaMLewis

In Column A, I selected the first cell (A4) for me, then went to Data > Data Validation and clicked on it. It opens this screen, which I input the following – A4 is the cell I’m in for “cell range”, the criteria is “list from a range”, and then I popped over to the tab with my ‘fuel library’ and highlighted the relevant data that I wanted to be in the menu: Food. So that was C2-C52 for my list of food. Make sure “show dropdown list in cell” is marked, because that’s what creates the dropdown in the cell. Click save.

Use the data validation section to choose to show a dropbox in each cell

You’ll want to drag that down to apply the drop-down to all the cells you want. Mine now looked like this, and you can see clicking the dropdown shows the menu to tap on.

Clicking a dropbox in the cell brings up the "menu" of food options from my Fuel Library tab

After I selected from my menu, I wanted column B to automatically put in the time. This gets obnoxious: google sheets has NOW() to put in the current time, but DO NOT USE THIS as the formula updates with the latest time any time you touch the spreadsheet.

I ended up having to use a google script (go to “Extensions” > Apps Script, here’s a tutorial with more detail) to create a function called onEdit() that I could reference in my spreadsheet. I use the old style legacy script editor in my screenshot below.

Older style app script editor for adding scripts to spreadsheet, showing the onEdit() function (see text below in post for what the script is)

Code I used, if you need to copy/paste:

function onEdit(e) {

var rr = e.range;

var ss = e.range.getSheet();

var headerRows = 2;  // # header rows to ignore

if (rr.getRow() <= headerRows) return;

var row = e.range.getRow();

var col = e.range.getColumn();

if(col == 1){

e.source.getActiveSheet().getRange(row,2).setValue(new Date());

}

}

After saving that script (File > Save), I went back to my spreadsheet and put this formula into the B column cells: =IFERROR(onEdit(),””). It fills in the current date/time (because onEdit tells it to if the A cell has been updated), and otherwise sits with a blank until it’s been changed.

Note: if you test your sheet, you’ll have to go back and paste in the formula to overwrite the date/time that gets updated by the script. I keep the formula without the “=” in a cell in the top right of my spreadsheet so I can copy/paste it when I’m testing and updating my sheet. You can also find it in a cell below and copy/paste from there as well.

Next, I wanted to populate my macronutrients on the tracker spreadsheet. For each cell in row 4, I used a VLOOKUP with the fuel name from A4 to look at the sheet with my library, and then use the column number from the fuel library sheet to reference which data element I want. I actually have things in a different order in my fuel library and my tracking sheet; so if you use my template later on or are recreating your own, pay attention to matching the headers from your tracker sheet and what’s in your library. The formula for this cell ended up being “=IFERROR(VLOOKUP(A4,’Fuel Library’!C:K,4, FALSE),””)”, again designed to leave the column blank if column A didn’t have a value, but if it does have a value, to prefill the number from Column 4 matching the fuel entry into this cell. Columns C-J on my tracker spreadsheet all use that formula, with the updated values to pull from the correctly matching column, to pre-populate my counts in the tracker spreadsheet.

Finally, the last thing I wanted was to track easily when I last ate. I could look at column B, but with a tired brain I want something more obvious that tracks how long it’s been. This also is again to maybe help Scott, who will be tasked with helping me stay on top of things, be able to check if I’m eating regularly and encourage me gently or less gently to be eating more as the hours wear on in my ultras.

I ended up creating a cell in the header that would track the last entry from column B. To do this, the formula I found is “INDEX(B4:B,MATCH(143^143,B4:B))”, which checks for the last number in column B starting in B4 and onward. It correctly pulls in the latest timestamp on the list.

Then, in another cell, I created “=NOW()-B2”, which is a good use for the NOW() formula I warned about, because it’s constantly updating every time the sheet gets touched, so that any time I go to update it’ll tell me how long it’s been since between now and the last time I ate.

But, that only updates every time I update the sheet, so if I want to glance at the sheet, it will be only from the last time I updated it… which is not what I want. To fix it, I need to change the autorefresh calculation settings. Go to File > Settings. Click “Calculations” tab, and the first drop down you want to change to be “On change and every minute”.

Under File > Settings there is a "Calculate" tab with a dropdown menu to choose to update on change plus every minute

Now it does what I want, updating that cell that uses the NOW() formula every minute, so this calculation is up to date even when the sheet hasn’t been changed!

However, I also decided I want to log electrolytes in my same spreadsheet, but not include it in my top “when did I last eat” calculator. So, I created column K and inserted the formula IF(A4=”Electrolytes”,””,B4), which checks to see if the Dropdown menu selection was Electrolytes. If so, it doesn’t do anything. If it’s not electrolytes, it repeats the B4 value, which is my formula to put the date and time. Then, I changed B2 to index and match on column K instead of B. My B2 formula now is INDEX(K4:K,MATCH(143^143,K4:K)), because K now has the food-only list of date and time stamps that I want to be tracking in my “when did I last eat” tracker. (If you don’t log electrolytes or don’t have anything else to exclude, you can keep B2 as indexing and matching on column B. But if you want to exclude anything, you can follow my example of using an additional column (my K) to check for things you do want to include and exclude the ones you don’t want. Also, you can hide columns if you don’t want to see them, so column K (or your ‘check for exclusions’ column wherever it ends up) could be hidden from view so it doesn’t distract your brain.

I also added conditional formatting to my tracker. Anytime A2, the time since eaten cell, is between 0-30 minutes, it’s green: indicating I’m on top of my fueling. 30-45 minutes it turns yellow as a warning that it’s time to eat. After 45 minutes, it’ll turn light red as a strong reminder that I’m off schedule.

I kept adding features, such as totaling my sodium consumption per hour, too, so I could track electrolytes+fuel sodium totals. Column L gets the formula =IF(((ABS((NOW()-B4))*1440)<60),F4,””) to check for the difference between the current time and the fuel entry, multiplying it by 1440 to convert to minutes and checking to see that it’s less than 60 minutes. If it is, then it prints the sodium value, and otherwise leaves it blank. (You could skip the ABS part as I was testing current, past, and future values and wanted it to stop throwing errors for future times that were calculated as negatives in the first argument). I then in C2 calculate the sum of those values for the total sodium for that hour, using =SUM(L4:L)

(I thought about tracking the past sodium per hour values to average and see how I did throughout the run on an hourly basis…but so far on my 3 long runs where I’ve used the spreadsheet, the very fact that I am using the tracker and glancing at the hourly total has kept me well on top of sodium and so I haven’t need that yet. However, if I eventually start to have long enough runs where this is an issue, I’ll probably go back and have it calculate the absolute hour sodium totals for retrospective analysis.)

This works great in the Google Sheets app on my phone, which is how I’ll be updating it during my ultras, although Scott can have it open on a browser tab when he’s at home working at his laptop. Every time I go for a long training run, I duplicate the template tab and label it with the date of the run and use it for logging my fueling.

(PS – if you didn’t know, you can rearrange the order of tabs in your sheet, so you can drag the one you want to be actively using to the left. This is useful in case the app closes on your phone and you’re re-opening the sheet fresh, so you don’t have to scroll to re-find the correct tab you want to be using for that run. In a browser, you can either drag and drop the tabs, or click the arrow next to the tab name and select “move left” or “move right”.)

Clicking the arrow to the right of a tab name in google sheets brings up a menu that includes the option to move the tab left or right

If you click to make a copy of a google spreadsheet, it pops up a link confirming you want to make a copy, and also might bring the app script functionality with it. If so, you can click the button to view the script (earlier in the blog post). If it doesn't include the warning about the script, remember to add the script yourself after you make a copy.

Take a look at my spreadsheet after you make a copy (click here to generate a copy if you didn’t use the previous mentioned link), and you’ll note in the README tab a few reminders to modify the fuel library and make sure you follow the steps to ensure that the script is associated with the sheet and validation is updated.

Obviously, you may not need lipase/pancrelipase/PERT and enzyme counts; if you do, your counts of enzymes needed and types of enzyme and quantity of enzymes will need updating; you may not need or want all of these macronutrients; and you’ll definitely be eating different fuel than I am, so you can update it however you like with what you’re eating and what you want to track.

This spreadsheet and the methods for building it can also be used for other purposes, such as tracking wait times or how long it took you to do something, etc.

2022 Strawberry Fields Forever Ultramarathon Race Report Recap

I recently ran my second-ever 50k ultramarathon. This is my attempt to provide a race recap or “race report”, which in part is to help people in the future considering this race and this course. (I couldn’t find a lot of race reports investigating this race!)

It’s also an effort to provide an example of how I executed fueling, enzyme dosing (because I have exocrine pancreatic insufficiency, known as EPI), and blood sugar management (because I have type 1 diabetes), because there’s also not a lot of practical guidance or examples of how people do this. A lot of it is individual, and what works for me won’t necessarily work for anyone, but if anything hopefully it will help other people feel not alone as they work to figure out what works for them!

Context of my running and training in preparation

I wrote quite a bit in this previous post about my training last year for a marathon and my first 50k. Basically, I’m slow, and I also choose to run/walk for my training and racing. This year I’ve been doing 30:60 intervals, meaning I run 30 seconds and walk 60 seconds.

Due to a combination of improved training (and having a year of training last year), as well as now having recognized I was not getting sufficient pancreatic enzymes so that I was not digesting and using the food I was eating effectively, this year has been going really well. I ended up training as far as a practice 50k about 5 weeks out from my race. I did several more mid- to high-20 mile runs as well. I also did a next-day run following my long runs, starting around 3-4 miles and eventually increasing to 8 miles the day after my 50k. The goal of these next-day runs was to practice running on tired legs.

Overall, I think this training was very effective for me. My training runs were easy paced, and I always felt like I could run more after I was done. I recovered well, and the next-day runs weren’t painful and I did not have to truncate or skip any of those planned runs. (Previous years, running always felt hard and I didn’t know what it was like to recover “well” until this year.) My paces also increased to about a minute/mile faster than last year’s easy pace. Again, that’s probably a combination of increased running overall and better digestion and recovery.

Last year I chose to run a marathon and then do a 50k while I was “trained up” for my marathon. This year, I wanted to do a 50k as a fitness assessment on the path to a 50 mile race this fall. I looked for local-ish 50k options that did not have much elevation, and found the Strawberry Fields Forever Ultra.

Why I chose this race, and the basics about this race

The Strawberry Fields Forever Ultra met most of my goal criteria, including that it was around the time that I wanted to run a 50k, so that I had almost 6 months to train and also before it got to be too hot and risked being during wildfire smoke season. (Sadly, that’s a season that now overlaps significantly with the summers here.) It’s local-ish, meaning we could drive to it, although we did spend the night before the race in the area just to save some stress the morning of the race. The race nicely started at 9am, and we drove home in the evening after the race.

The race is on a 10k (6.2 miles) looped course in North Bonneville, Washington, and hosted a 10k event (1 lap), a 50k event (5 laps), and also had 100k (10 laps) or (almost) 100 miles (16 laps). It does have a little bit of elevation – or “little” by ultramarathon standards. The site and all reports describe one hill and net 200 feet of elevation gain and loss. I didn’t love the idea of a 200 foot hill, but thought I could make do. It also describes the course as “grass and dirt” trails. You’ll see a map later where I’ve described some key points on the course, and it’s also worth noting that this course is very “crew-able”. Most people hang out at the start/finish, since it’s “just” a 10k loop and people are looping through pretty frequently. However, if you want to, either for moral or practical support, crew could walk over to various points, or my husband brought his e-bike and biked around between points on the course very easily using a mix of the other trails and actual roads nearby.

The course is well marked. Any turn had a white sign with a black arrow on it and also white arrows drawn on the ground, and there were dozens of little red/pink fluorescent flags marking the course. Any time there was a fork in the path, these flags (usually 2-3 for emphasis, which was excellent for tired brains) would guide you to the correct direction.

The nice thing about this race is it includes the 100 mile option and that has a course limit of 30 hours, which means all the other distances also have this course limit of 30 hours. That’s fantastic when a lot of 50k or 50 mile (or 100k, which is 62 miles) courses might have 12 hour or similar tighter course limits. If you wanted to have a nice long opportunity to cover the distance, with the ability to stop and rest (or nap/sleep), this is a great option for that.

With the 50k, I was aiming to match or ideally beat my time from my first 50k, recognizing that this course is harder given the terrain and hill. However, I think my fitness is higher, so beating that time even with the elevation gain seemed reasonable.

Special conditions and challenges of the 2022 Strawberry Fields Forever Ultramarathon

It’s worth noting that in 2021 there was a record abnormal heat wave due to a “heat dome” that made it 100+ degrees (F) during the race. Yikes. I read about that and I am not willing to run a race when I have not trained for that type of heat (or any heat), so I actually waited until the week before the race to officially sign up after I saw the forecast for the race. The forecast originally was 80 F, then bounced around mid 60s to mid 70s, all of which seemed doable. I wouldn’t mind some rain during the race, either, as rainy 50s and 60s is what I’ve been training in for months.

But just to make things interesting, for the 2022 event the Pacific Northwest got an “atmospheric river” that dumped inches of rain on Thursday..and Friday. Gulp. Scott and I drove down to spend the night Friday night before the race, and it was dumping hard rain. I began to worry about the mud that would be on the course before we even started the race. However, the rain finished overnight and we woke up to everything being wet, but not actively raining. It was actually fairly warm (60s), so even if it drizzled during the race it wouldn’t be chilly.

During the start of the race, the race director said we would get wet and joked (I thought) about practicing our backstroke. Then the race started, and we took off.

My race recap / race report the 2022 Strawberry Fields Forever Ultramarathon

I’ve included a picture below that I was sent a month or so before the race when I asked for a course map, and a second picture because I also asked for the elevation profile. I’ve marked with letters (A-I) points on the course that I’ll describe below for reference, and we ran counterclockwise this year so the elevation map I’ve marked with matching letters where “A” is on the right and “I” is on the left, matching how I experienced the course.

The course is slightly different in the start/finish area, but otherwise is 95% matching what we actually ran, so I didn’t bother grabbing my actual course map from my run since this one was handy and a lot cleaner than my Runkeeper-derived map of the race.

StrawberryFieldsForever-Ultra-Elevation-Profile

My Runkeeper elevation profile of the 50k (5 repeated laps) looked like this:
Runkeeper elevation profile of 5 loops on the Strawberry Fields Forever 50k course

I’ll describe my first experience through the course (Lap 1) in more detail, then a couple of thoughts about the experiences of the subsequent laps, in part to describe fueling and other choices I made.

Lap 1:

We left the start by running across the soccer field and getting on a paved path that hooked around the ballfield and then headed out a gate and up The Hill. This was the one hill I thought was on the course. I ran a little bit and passed a few people who walked on a shallower slope, then I also converted to a walk for the rest of the hill. It was the most crowded race start I’ve done, because there were so many people (150 across the 10k, 50k, 100k, and 100 miler) and such a short distance between the start and this hill. The Hill, as I thought of it, is point A on the course map.

Luckily, heading up the hill there are gorgeous purple wildflowers along the path and mountain views. At the top of the hill there are some benches at the point where we took a left turn and headed down the hill, going down the same elevation in about half a mile so it was longer than the uphill section. This downhill slope (B) was very runnable and gravel covered, whereas going up the hill was more dirt and mud.

At the bottom of the hill, there was a hairpin turn and we turned and headed back up the hill, although not all the way up, and more along a plateau in the side of the hill. The “plateau” is point C on the map. I thought it would be runnable once I got back up the initial hill, but it was mud pit after mud pit, and I would have two steps of running in between mud pits to carefully walk through. It was really frustrating. I ended up texting to my parents and Scott that it was about 1.7 miles of mud (from the uphill, and the plateau) before I got to some gravel that was more easily runnable. Woohoo for gravel! This was a nice, short downhill slope (D) before we flattened out and switched back to dirt and more mud pits.

This was the E area, although it did feel more runnable than the plateau because there were longer stretches between muddy sections.

Eventually, we saw the river and came out from the trail into a parking lot and then jogged over onto the trail that parallels the river for a while. This trail that I thought of as “River Road” (starting around point F) is just mowed grass and is between a sharp bluff drop with opening where people would be down at the river fishing, and in some cases we were running *underneath* fishing lines from the parking spots down to the river! There were a few people who would be walking back and forth from cars to the river, but in general they were all very courteous and there was no obstruction of the trail. Despite the mowed grass aspect of the trail, this stretch physically and psychologically felt easier because there were no mud pits for 90% of it. Near the end there were a few muddy areas right about the point we hopped back over into the road to connect up a gravel road for a short spurt.

This year, the race actually put a bonus aid station out here. I didn’t partake, but they had a tent up with two volunteers who were cheerful and kind to passing runners, and it looked like they had giant things of gatorade or water, bottled water, and some sugared soda. They probably had other stuff, but that’s just what I saw when passing.

After that short gravel road bit, we turned back onto a dirt trail that led us to the river. Not the big river we had been running next to, but the place where the Columbia River overflowed the trail and we had to cross it. This is what the race director meant by practicing our backstroke.

You can see a video in this tweet of how deep and far across you had to get in this river crossing (around point G, but hopefully in future years this isn’t a point of interest on the map!!)

Showing a text on my watch of my BIL warning me about a river crossing

Coming out of the river, my feet were like blocks of ice. I cheered up at the thought that I had finished the wet feet portion of the course and I’d dry off before I looped back around and hit the muddy hill and plateau again. But, sadly, just around the next curve, came a mud POND. Not a pit, a pond.

Showing how bad the mud was

Again, ankle deep water and mud, not just once but in three different ponds all within 30 seconds or so of each other. It was really frustrating, and obviously you can’t run through them, so it slowed you down.

Then finally after the river crossing and the mud ponds, we hooked a right into a nice, forest trail that we spent about a mile and a half in (point H). It had a few muddy spots like you would normally expect to get muddy on a trail, but it wasn’t ankle deep or water filled or anything else. It was a nice relief!

Then we turned out of the forest and crossed a road and headed up one more (tiny, but it felt annoying despite how small it looks on the elevation profile) hill (point I), ran down the other side of that slope, stepped across another mud pond onto a pleasingly gravel path, and took the gravel path about .3 miles back all the way to complete the first full lap.

Phew.

I actually made pretty good time the first loop despite not knowing about all the mud or river crossing challenges. I was pleased with my time which was on track with my plan. Scott took my pack about .1 miles before I entered the start/finish area and brought it back to me refilled as I exited the start/finish area.

Lap 2:

The second lap was pretty similar. The Hill (A) felt remarkably harder after having experienced the first loop. I did try to run more of the downhill (B) as I recognized I’d make up some time from the walking climb as well as knowing I couldn’t run up the plateau or some of the mud pits along the plateau (C) as well as I had expected. I also decided running in the mud pits didn’t work, and went with the safer approach of stepping through them and then running 2 steps in between. I was a little slower this time, but still a reasonable pace for my goals.

The rest of the loop was roughly the same as the first, the mud was obnoxious, the river crossing freezing, the mud obnoxious again, and relief at running through the forest.

Scott met me at the end of the river road and biked along the short gravel section with me and went ahead so he could park his bike and take video of my second river crossing, which is the video above. I was thrilled to have video of that, because the static pictures of the river crossing didn’t feel like it did the depth and breadth of the water justice!

At the end of lap 2, Scott grabbed my pack again at the end of the loop and said he’d figured out where to meet me to give it back to me after the hill…if I wanted that. Yes, please! The bottom of the hill where you hairpin turn to go back up the plateau is the 1 mile marker point, so that means I ran the first mile of the third lap without my pack, and not having the weight of my full pack (almost 3L of water and lots of snacks and supplies: more on that pack below) was really helpful for my third time up the hill. He met me as planned at the bottom of the downhill (B) and I took my pack back which made a much nicer start to lap 3.

Lap 3:

Lap 3 for some reason I came out of the river crossing and the mud ponds feeling like I got extra mud in my right shoe. It felt gritty around the right side of my right food, and I was worried about having been running for so many hours with soaked feet. I decided to stop at a bench in the forest section and swap for dry socks. In retrospect, I wish I had stopped somewhere else, because I got swarmed by these moth/gnat/mosquito things that looked gross (dozens on my leg within a minute of sitting there) that I couldn’t brush off effectively while I was trying to remove my gaiters, untie my shoes, take my shoes off, peel my socks and bandaids and lambs wool off, put lubrication back on my toes, put more lambs wool on my toes, put the socks and shoes back on, and re-do my gaiters. Sadly, it took me 6 minutes despite me moving as fast as I could to do all of those things (this was a high/weirdly designed bench in a shack that looked like a bus stop in the middle of the woods, so it wasn’t the best way to sit, but I thought it was better than sitting on the ground).

(The bugs didn’t hurt me at the time, but two days later my dozens of bites all over my leg are red and swollen, though thankfully they only itch when they have something chafing against them.)

Anyway, I stood up and took off again and was frustrated knowing that it had taken 6 minutes and basically eaten the margin of time I had against my previous 50k time. I saw Scott about a quarter of a mile later, and I saw him right as I realized I had also somewhere lost my baggie of electrolyte pills. Argh! I didn’t have back up for those (although I had given Scott backups of everything else), so that spiked my stress levels as I was due for some electrolytes and wasn’t sure how I’d do with 3 or so more hours without them.

I gave Scott my pack and tasked him with checking my brother-in-law’s setup to see if he had spare electrolytes, while he was refilling my pack to give me in lap 4.

Lap 4:

I was pretty grumpy given the sock timing and the electrolyte mishap as I headed into lap 4. The hill still sucked, but I told myself “only one more hill after this!” and that thought cheered me up.

Scott had found two electrolyte options from my brother-in-law and brought those to me at the end of mile 1 (again, bottom of B slope) with my pack. He found two chewable and two swallow pills, so I had options for electrolytes. I chewed the first electrolyte tab as I headed up the plateau, and again talked myself through the mud pits with “only one more time through the mud pits after this!”.

I also tried overall to bounce back from the last of mile 4 where I let myself get frustrated, and try to take more advantage of the runnable parts of the course. I ran downhill (B) more than the previous laps, mostly ignoring the audio cues of my 30:60 intervals and probably running more like 45:30 or so. Similarly, the downhill gravel after the mud pits (D) I ran most of without paying attention to the audio run cues.

Scott this time also met me at the start of the river road section, and I gave him my pack again and asked him to take some things out that he had put in. He put in a bag with two pairs of replacement socks instead of just one pair of socks, and also put in an extra beef stick even though I didn’t ask for it. I asked him to remove it, and he did, but explained he had put it in just in case he didn’t find the electrolytes because it had 375g of sodium. (Sodium is primarily the electrolyte I am sensitive to and care most about). So this was actually a smart thing, although because I haven’t practiced eating larger amounts of protein and experienced enzyme dosing for it on the run, I would be pretty nervous about eating it in a race, so that made me a bit unnecessarily grumpy. Overall though, it was great to see him extra times on the course at this point, and I don’t know if he noticed how grumpy I was, but if he did he ignored it and I cheered up again knowing I only had “one more” of everything after this lap!

The other thing that helped was he biked my pack down the road to just before the river crossing, so I ran the river road section like I did lap 3 and 4 on the hill, without a pack. This gave me more energy and I found myself adding 5-10 seconds to the start of my run intervals to extend them.

The 4th river crossing was no less obnoxious and cold, but this time it and the mud ponds didn’t seem to embed grit inside my shoes, so I knew I would finish with the same pair of socks and not need another change to finish the race.

Lap 5:

I was so glad I was only running the 50k so that I only had 5 laps to do!

For the last lap, I was determined to finish strong. I thought I had a chance of making up a tiny bit of the sock change time that I had lost. I walked up the hill, but again ran more than my scheduled intervals downhill, grabbed my bag from Scott, picked my way across the mud pits for the final time (woohoo!), ran the downhill and ran a little long and more efficiently on the single track to the river road.

Scott took my pack again at the river road, and I swapped my intervals to be 30:45, since I was already running closer to that and I knew I only had 3.5 or so miles to go. I took my pack back at the end of river road and did my last-ever ice cold river crossing and mud pond extravaganza. After I left the last mud pond and turned into the forest, I switched my intervals to 30:30. I managed to keep my 30:30 intervals and stayed pretty quick – my last mile and a half was the fastest of the entire race!

I came into the finish line strong, as I had hoped to finish. Woohoo!

Overall strengths and positives from the race

Overall, running-wise I performed fairly well. I had a strong first lap and decent second lap, and I got more efficient on the laps as I went, staying focused and taking advantage of the more runnable parts of the course. I finished strong, with 30:45 intervals for over a mile and 30:30 intervals for over a mile to the finish.

Also, I didn’t quit after experiencing the river crossing and the mud ponds and the mud pits of the first lap. This wasn’t an “A” race for me or my first time at the distance, so it would’ve been really easy to quit. I probably didn’t in part because we did pay to spend the night before and drove all that way, and I didn’t want to have “wasted” Scott’s time by quitting, when I was very capable of continuing and wasn’t injured. But I’m proud of mostly the way I handled the challenges of the course, and for how I readjusted from the mental low and frustration after realizing how long my sock change took in lap 3. I’m also pleased that I didn’t get injured, given the terrain (mud, river crossing, and uneven grass to run on for most of the course). I’m also pleased and amazed I didn’t hurt my feet, cause major blisters, or have anything really happen to them after hours of wet, muddy, never-drying-off feet.

The huge positive was my fueling, electrolytes, and blood glucose management.

I started taking my electrolyte pills that have 200+mg of sodium at about 45 minutes into the race, on schedule. My snack choices also have 100-150mg of sodium, which allowed me to not take electrolyte pills as often as I would otherwise need to (or on a hotter day with more sweat – it was a damp, mid-60s day but I didn’t sweat as much as I usually do). But even with losing my electrolytes, I used two chewable 100mg sodium electrolytes instead and otherwise ended up with sufficient electrolytes. Even with ideal electrolyte supplementation, I’m very sensitive to sodium losses and am a salty sweater, and I have a distinct feeling when my electrolytes are insufficient, so not having that feeling during after the race was a big positive for me.

So was my fueling overall. The race started at 9am, and I woke up at 6am to eat my usual pre-race breakfast (a handful of pecans, plus my enzyme supplementation) so that it would both digest effectively and also be done hitting my blood sugar by the time the race started. My BGs were flat 120s or 130s when I started, which is how I like them. I took my first snack about an hour and 10 minutes into the race, which is about 15g carb (10g fat, 2g protein) of chili cheese flavored Fritos. For this, I didn’t dose any insulin as I was in range, and I took one lipase-only enzyme (which covers about 8g of fat for me) and one multi-enzyme (that covers about 6g of fat and probably over a dozen grams of protein). My second snack was an hour later, when I had a gluten free salted caramel Honey Stinger stroopwaffle (21g carb, 6 fat, 1 protein). For the stroopwaffle I ended up only taking a lipase-only pill to cover the fat, even though there’s 1g of protein. For me, I seem to be ok (or have no symptoms) from 2-3g of uncovered fat and 1-2g of uncovered protein. Anything more than that I like to dose enzymes for, although it depends on the situation. Throughout the day, I always did 1 lipase-only and 1 multi-enzyme for the Fritos, and 1 lipase-only for the stroopwaffle, and that seemed to work fine for me. I think I did a 0.3u (less than a third of the total insulin I would normally need) bolus for my stroopwaffle because I was around 150 mg/dL at the time, having risen following my un-covered Frito snack, and I thought I would need a tiny bit of insulin. This was perfect, and I came back down and flattened out. An hour and 20 minutes after that, I did another round of Fritos. An hour or so after that, a second stroopwaffle – but this time I didn’t dose any insulin for it as my BG was on a downward slope. An hour later, more Fritos. A little bit after that, I did my one single sugar-only correction (an 8g carb Airhead mini) as I was still sliding down toward 90 mg/dL, and while that’s nowhere near low, I thought my Fritos might hit a little late and I wanted to be sure I didn’t experience the feeling of a low. This was during the latter half of loop 4 when I was starting to increase my intensity, so I also knew I’d likely burn a little more glucose and it would balance out – and it did! I did one last round of Fritos during lap 5.

This all worked perfectly. I had 100% time in range between 90 and 150 mg/dL, even with 102g of “real food” carbs (15g x 4 servings of Fritos, 21g x 2 waffles), and one 8g Airhead mini, so in total I had 110g grams of carbs across ~7+ hours. This perfectly matched my needs with my run/walk moderate efforts.

I also nailed the enzymes, as during the race I didn’t have any GI-related symptoms and after the race and the next day (which is the ultimate verdict for me with EPI), no symptoms.

So it seems like my practice and testing with low carbs, Fritos, and waffles worked out well! I had a few other snacks in my pack (yogurt-covered pretzels, peanut butter pretzel nuggets), but I never thought of wanting them or wanting something different. I did plan to try to do 2 snacks per hour, but I ended up doing about 1 per hour. I probably could have tolerated more, but I wasn’t hungry, my BGs were great, and so although it wasn’t quite according to my original plan I think this was ideal for me and my effort level on race day.

The final thing I think went well was deciding on the fly after loop 2 to have Scott take my pack until after the hill (so I ran the up/downhill mile without it), and then for additional stretches along river road in laps 4 and 5. I had my pocket of my shorts packed with dozens of Airheads and mints, so I was fine in terms of blood sugar management and definitely didn’t need things for a mile at a time. I’m usually concerned about staying hydrated and having water whenever I want to sip, plus for swallowing electrolytes and enzyme pills to go with my snacks, but I think on this course with the number of points Scott could meet me (after B, at F all through G, and from I to the finish), I could have gotten away with not having my pack the whole time; having WAY less water in the pack (I definitely didn’t need to haul 3L the whole time, that was for when I might not see Scott every 2-3 laps) and only one of each snack at a time.

Areas for improvement from my race

I trained primarily on gravel or paved trails and roads, but despite the “easy” elevation profile and terrain, this was essentially my first trail ultra. I coped really well with the terrain, but the cognitive burden of all the challenges (Mud pits! River crossing! Mud ponds!) added up. I’d probably do a little more trail running and hills (although I did some) in the final weeks before the race to help condition my brain a little more.

I’ll also continue to practice fueling so I can eat more regularly than every hour to an hour and a half, even though this was the most I’ve ever eaten during a run, I did well with the quantities, and my enzyme and BG management were also A+. But I didn’t eat as much as I planned for, and I think that might’ve helped with the cognitive fatigue, too, by at least 5-10%.

I also now have the experience of a “stop” during a race, in this case to swap my socks. I’ve only run one ultra and never stopped before to do gear changes, so that experience probably was sufficient prep for future stops, although I do want to be mentally stronger/less frustrated by unanticipated problem solving stops.

Specific to this course, as mentioned above, I could’ve gotten away with less supplies – food and water – in my pack. I actually ran a Ragnar relay race with a group of fellow T1s a few years back where I finished my run segment and…no one was there to meet me. They went for Starbucks and took too long to get there, so I had to stand in the finishing chute waiting for 10-15 minutes until someone showed up to start the next run leg. Oh, and that happened in two of the three legs I ran that day. Ooof. Standing there tired, hot, with nothing to eat or drink, likely added to my already life-with-type-1-diabetes-driven-experiences of always carrying more than enough stuff. But I could’ve gotten away very comfortably with carrying 1L of water and one set of each type of snacks at a time, given that Scott could meet me at 1 mile (end of B), start (F) and end of river road (before G), and at the finish, so I would never have been more than 2-2.5 miles without a refill, and honestly he could’ve gotten to every spot on the trail barring the river crossing bit to meet me if I was really in need of something. Less weight would’ve made it easier to push a little harder along the way. Basically, I carried gear like I was running a solo 30 mile effort at a time, which was safe but not necessary given the course. If I re-ran this race, I’d feel a lot more comfortable with minimal supplies.

Surprises from my race

I crossed the finish line, stopped to get my medal, then was waiting for my brother-in-law to finish another lap (he ran the 100k: 62 miles) before Scott and I left. I sat down for 30 minutes and then walked to the car, but despite sitting for a while, I was not as stiff and sore as I expected. And getting home after a 3.5 hour car ride…again I was shocked at how minimally stiff I was walking into the house. The next morning? More surprises at how little stiff and sore I was. By day 3, I felt like I had run a normal week the week prior. So in general, I think this is reinforcement that I trained really well for the distance and my long runs up to 50k and the short to medium next day runs also likely helped. I physically recovered well, which is again part training but also probably better fueling during the race, and of course now digesting everything that I ate during and after the race with enzyme supplementation for EPI!

However, the interesting (almost negative, but mostly interesting) thing for me has been what I perceived to be adrenal-type fatigue or stress hormone fatigue. I think it’s because I was unused to focusing on challenging trail conditions for so many hours, compared to running the same length of hours on “easy” paved or gravel trails. I actually didn’t listen to an audiobook, music, or podcast for about half of the race, because I was so stimulated by the course itself. What I feel is adrenal fatigue isn’t just being physically or mentally tired but something different that I haven’t experienced before. I’m listening to my body and resting a lot, and I waited until day 4 to do my first easy, slow run with much longer walk intervals (30s run, 90s walk instead of my usual 30:60). Day 1 and 2 had a lot of fatigue and I didn’t feel like doing much, Day 3 had notable improvement on fatigue and my legs and body physically felt back to normal for me. Day 4 I ran slowly, Day 5 I stuck with walking and felt more fatigue but no physical issues, Day 6 again I chose to walk because I didn’t feel like my energy had fully returned. I’ll probably stick with easy, longer walk interval runs for the next week or two with fewer days running until I feel like my fatigue is gone.

General thoughts about ultramarathon training and effective ultra race preparation

I think preparation makes a difference in ultramarathon running. Or maybe that’s just my personality? But a lot of my goal for this race was to learn what I could about the course and the race setup, imagine and plan for the experience I wanted, plan for problem solving (blisters, fuel, enzymes, BGs, etc), and be ready and able to adapt while being aware that I’d likely be tired and mentally fatigued. Generally, any preparation I could do in terms of deciding and making plans, preparing supplies, etc would be beneficial.

Some of the preparation included making lists in the weeks prior about the supplies I’d need in my pack, what Scott should have to refill my pack, what I’d need the night and morning before since we would not be at home, and after-race supplies for the 3.5h drive home.

From the lists, the week before the race I began grouping things. I had my running pack filled and ready to go. I packed my race outfit in a gallon bag, a full set of backup clothes in another gallon bag and labeled them, along with a separate post-run outfit and flip flops for the drive home. I also included a washcloth for wiping sweat or mud off after the run, and I certainly ended up needing that! I packed an extra pair of shoes and about 4 extra pairs of socks. I also had separate baggies with bandaids of different sizes, pre-cut strips of kinesio tape for my leg and smaller patches for blisters, extra squirrel nut butter sticks for anti-chafing purposes, as well as extra lambs wool (that I lay across the top of my toes to prevent socks from rubbing when they get wet from sweat or…river crossings, plus I can use it for padding between my toes or other blister-developing spots). I had sunscreen, bug spray, sungless, rain hat, and my sunny-weather running visor that wicks away sweat. I had low BG carbs for me to put in my pockets, a backup bag for Scott to refill, and a backup to the backup. The same for my fuel stash: my backpack was packed, I packed a small baggie for Scott as well as a larger bag with 5-7 of everything I thought I might want, and also an emergency backup baggie of enzymes.

*The only thing I didn’t have was a backup baggie of electrolyte pills. Next time, I’ll add this to my list and treat them like enzymes to make sure I have a separate backup stash.

I even made a list and gave it to Scott that mapped out where key things were for during and after the race. I don’t think he had to use it, because he was only digging through the snack bag for waffles and Fritos, but I did that so I didn’t have to remember where I had put my extra socks or my spare bandaids, etc. He basically had a map of what was in each larger bag. All of this was to reduce the decision and communication because I knew I’d have decision fatigue.

This also went for post-race planning. I told Scott to encourage me to change clothes, and it was worth the energy to change so I didn’t sit in cold, wet clothes for the long drive home. I pre-made a gluten free ham and cheese quesadilla (take two tortillas, fill with shredded cheese and slices of ham, microwave, cut into quarters, stick in baggies, mark with fat/protein/carb counts, and refrigerate) so we could warm that up in the car (this is what I use) so I had something to eat on the way home that wasn’t more Fritos or waffles. I didn’t end up wanting it, but I also brought a can of beef stew with carrots and potatoes, that I generally like as a post-race or post-run meal, and a plastic container and a spoon so I could warm up the stew if I wanted it. Again, all of this pre-planned and put on the list weeks prior to the race so I didn’t forget things like the container or the spoon.

The other thing I think about a lot is practicing everything I want to do for a race during a training run. People talk about eating the same foods, wearing the same clothes, etc. I think for those of us with type 1 diabetes (or celiac, EPI, or anything else), it’s even more important. With T1D, it’s so helpful to have the experience adjusting to changing BG levels and knowing what to do when you’re dropping or low and having a snack, vs in range and having a fueling snack, or high and having a fueling snack. I had 100% TIR during this run, but I didn’t have that during all of my training runs. Sometimes I’d plateau around 180 mg/dL and be over-cautious and not bring my BGs down effectively; other times I’d overshoot and cause a drop that required extra carbs to prevent or minimize a low. Lots of practice went into making this 100% TIR day happen, and some of it was probably a bit of luck mixed in with all the practice!

But generally, practice makes it a lot easier to know what to do on the fly during a race when you’re tired, stressed, and maybe crossing an icy cold river that wasn’t supposed to be part of your course experience. All that helps you make the best possible decisions in the weirdest of situations. That’s the best you can hope for with ultrarunning!

Reflecting on 4 months with Exocrine Pancreatic Insufficiency (EPI) and Experiences with Pancreatic Enzyme Replacement Therapy (PERT)

Exocrine Pancreatic Insufficiency (EPI or PEI) is an invisible disease – you don’t see or hear much of it and there’s not a lot of information for patients online, nor information written by people with EPI. (That’s in part why I’ve been documenting my experiences with EPI – more at DIYPS.org/EPI if you want to see the other EPI-related posts that I’ve written, including about PERT Pilot, the first iOS app for Exocrine Pancreatic Insufficiency! It’s an iOS app that allows you to record as many meals as you want, the PERT dosing and outcomes, to help you visualize and review more of your PERT dosing data!).

I’ve now spent more than 4 months with (known) EPI and taking pancreatic enzyme replacement therapy (PERT), and I’m sharing what I’ve found so far that’s worked for me. I also wanted to share an update on my experiences and what I wish I had known at the start that I know now.

Mainly, it gets better. It gets easier.

4 months on PERT for EPI

“It” being how I felt and now feel, and the process of figuring out how much enzymes to take, and the process of working more math into the choices of what, when, and how I was eating. It’s a lot of work, but it has gotten easier. And I feel a lot better. I now have multi-week streaks where I have perfect dosing for everything that I eat and dose for, and it’s rare to not get it right.

The early weeks were not this great: I definitely felt better than before, but not “back to normal”.

Now, I feel “back to normal” like I think I did 2-3 years ago before symptoms became noticeable. When I don’t manage to dose perfectly, the symptoms are way more minimal than previously, in part due to the fact that I’ve had so many days of feeling great and in part due to the fact that the margin of error is a lot smaller since I’ve figured out a good ratio of lipase:fat and protease:protein that works well and reliably for me.

This has confirmed for me that titrating doses of enzyme does matter. I documented everything I was eating (including listing out the amount of fat and protein) and the amount/level of enzymes I was taking. Over time, I was able to see a general threshold above/below which dosing usually worked or didn’t work, and then test slightly smaller amounts of fat and/or protein to get to an amount that reliably “worked” with that size of enzyme dose. From there, it was simple math to divide the thousand units of lipase in that size of enzyme dose by the grams of fat or protein to identify the ratio of fat:lipase or protein:protease that I needed. This has helped me get the right dose of enzymes for every meal. It has also enabled me to then choose between the more expensive and higher-dose prescription enzyme pills I have, or choose a combination of prescription and smaller-dose single or multi-enzyme over the counter pills. This ends up giving me more flexibility in the cost of enzymes it takes to cover the food I want to eat (or snack, or treat, or whatever) as well as more precision with dosing the right level of enzyme instead of 1x, 2x, 3x (etc.) a single dose size prescription pill.

In addition to feeling a lot better simply by having better GI-related outcomes and massive reduction in symptoms 95% of the time, my energy levels are way up. I’m also training to run an ultramarathon again this year, and the way I feel during training this year (with enzymes) compared to last year is startling. Even though I have another year’s worth of experience running that I didn’t have last year, the way I feel during and after runs is likely more attributable to the fact that I’m now digesting what I’m eating.

Additionally, the diversity of food that I’m choosing to eat is increasing constantly. I started conservatively, in part due to trying to figure out if I still had any FODMAP-related sensitivity, and also to make it easier to get the math “right” to figure out my optimal dose. As I got confident with my ratios and dosing PERT, I began eating a wider selection of foods, and finally have eaten my way back to eating actual onions (!) in the form of gluten free onion rings. They were delicious, and gave me zero problems. So I’m now confident the FODMAP-perceived sensitivities was really the increasing sensitivity to fat and protein as my elastase levels were dropping. It’s wonderful to not be as restricted in my food options. (I still have celiac disease and eat 100% gluten free and can’t have any cross-contamination, but after almost a year of not eating onion or garlic in any form including “natural flavors” of foods… “just” eating gluten free feels amazingly plentiful in options now.)

And because I’ve eaten more and a greater selection of foods, the thought of eating food doesn’t scare me anymore. I don’t cringe at the thought of actually eating, like I used to. I know it’s a matter of estimating or counting the fat and protein and dosing for it. If in doubt, I try to round up the number of pills I’m taking to provide a buffer. Unlike insulin, taking a little too much enzyme doesn’t hurt (other than the cost). But also like insulin (after almost 20 years), I am no longer counting the cost of every dose in my head with every meal. That definitely took over 3 months, because before then I was swallowing a PERT pill and knowing each and every one costs $9. Ugh. So that’s an improvement, even though I’m still aware of the cost, it’s not quite as bothersome to me on an every-instance basis.

Things aren’t perfect, though, despite it being a lot better. I still get overwhelmed sometimes by the amount of work to decide what I want to eat and how I’m going to estimate what is in it to try to figure out how much PERT to dose.

Some of the strategies I’ve identified that help reduce being overwhelmed include:

  • Asking for help when I can. I ask Scott (my husband) when he’s standing in the kitchen to glance at a label of a food and tell me the counts (grams of fat and protein per serving), so I can decide if I want to build a meal with that item in it. I also sometimes ask him to help me portion out individual servings of foods, such as taking a larger bag of chips and telling him the serving size that I want and asking him to weigh them out.
  • Separate the work of preparing (and counting) food from the process of deciding what to eat. (I hate using a scale and weighing things out, but it’s been really helpful to pre-portion snacks and other items). Having the pre-portioned and pre-counted amounts helps me then more easily incorporate them on the fly, because I’ve already done the counting work of figuring out what’s in them. (I either make a note on my phone in a spreadsheet or write with a marker on the baggie what the counts are.) Separating the work in advance from the decision of what to eat when it’s time to eat helps me cut down on the decision fatigue that occurs a lot for me.
  • Buying individual portions and “snack size” items of things I regularly eat. When I can find them, and thankfully I can afford to, I try to buy individual sizes of things that are pre-packaged and have the nutrition label for that serving size. It’s less work to portion it out and figure out the counts for it, so while it’s sometimes more expensive it saves me time and makes me more likely to incorporate it into my food choices.
  • Asking for help estimating what’s in mystery food (e.g. unlabeled/uncounted food items). I’ve got almost 20 years experience of estimating carb counts, but only a few months attempts of trying to estimate fat and protein counts. Sometimes I ask Scott to pitch in an estimate. Sometimes we try to look up an equivalent item (e.g., if assessing a local gluten free hamburger we got as takeout food, we’ll look up online what a few other chain restaurant hamburgers would be, and use that to triangulate). Sometimes he’ll weigh it on the scale and we’ll eyeball proportions of fat and protein in the meat versus the vegetables or rice. I’m already getting better at guesstimating, so like carb counting I imagine this will continue to get easier over time.

Managing decision fatigue is now the biggest hassle for me. I have developed a nice routine for taking counts and converting that to the right PERT doses, but I still get frustrated with having to think about what I’m eating and how I’m going to dose for it sometimes. This may be somewhat influenced by the fact that I’m running a lot and trying to eat a slightly higher level of protein than I would naturally be picking out in my diet. So having to pay attention to everything to count it for dosing and overall trying to achieve a general higher baseline of protein sometimes gets annoying (although obviously the increased need for protein is a choice, whereas EPI and dosing in general is not!).

In general, I’ve not found it hard to remember to take my enzymes. I’ve developed habits around figuring out my counts, converting that to what number and type of pills I’m taking, and I get those out to take with my first bite and/or throughout my meal, depending on the number. One thing that has helped with this is getting smaller pill cases (like these – they’re purple! They also come in white or multicolor) that I visually don’t hate and can put both the prescription and over the counter pills in. I have 2-3 of these filled and ready to go at any given time, which makes it easy to grab one when I head out for the day, or to have sitting in different spots on my kitchen island/counter so I have the visual reminder in addition to my traditional “prescription” bottle.

The other aspect aside from decision fatigue is the stress of uncertainty around food. I took a trip recently and it was very stressful being out of my routine at home for the first time since we realized I had EPI. I had to take a lot of enzymes with me, take extras in case something happened to them, pack snacks, figure out food in advance but also be ready to figure out food on the fly. This included guessing what was in airplane (gluten free) food. On the first flight, I gave Scott my dry airplane chicken because it didn’t look good or even worth the PERT, and ate snacks from my bag instead. On the flight home, the chicken had a sauce (woohoo) and came with cheesy potatoes, so I rounded up my dose guess and things were fine. In between on the trip, I also erred on the side of caution and rounded up my doses.That meant I took a little more than usual, but I had already factored that into the amount of enzymes I had packed for the trip. So that went fine. But the uncertainty in what I’d be eating for several days was stressful and hard. To help work around that, I had picked a hotel near a gluten free bakery and near a gluten free restaurant that I knew from a previous trip, so that at least I could reduce the uncertainty of “is there anything celiac-safe (gluten free) that I can eat” (which used to be my sole concern when traveling) and limit myself only to the uncertainty of “what do I dose for this?” every time I ate. That helped. So I’ll probably continue to use the pre-planning skills I learned from living with celiac because the uncertainty at every meal for EPI is a lot, especially when jet-lagged, and so everything I can do to pre-estimate or pre-plan and make sure I have access to food pays off.

(As I mentioned at the start of this post, you can find my previous posts about EPI at DIYPS.org/EPI.

Why it feels harder to dose pancreatic enzyme replacement therapy (PERT) than insulin

In 2002 when I was diagnosed with Type 1 diabetes, I struggled with being handed a vial of insulin and told vaguely to eat X amount of food and take Y amount of insulin. There was no ability to eat more and adjust the dose accordingly. It was frustrating. The only tool I had was a huge (imagine three iPhone 13 or equivalently large smartphones sitting on top of each other) blood glucose meter that took a lot of blood and a long time (a minute or more) to return a single blood glucose data point. The feedback loop wasn’t very useful, even when I tested my blood sugar manually 10-14 times per day.

Thankfully, in the last two decades, diabetes tools have evolved. Meters got smaller, faster, and take less blood. There has also been the devlopment of continuous glucose monitors (CGM) which I can wear and get near real-time readings of glucose data and can see what’s happened in the past. And, paired with an algorithm that also knows about the history of any insulin dosing on my insulin pump, and it can automatically adjust my insulin delivery in real time to predict, prevent, and reduce hypo- and hyperglycemia. (AID is awesome and if you haven’t heard about it, there’s a 4-minute free animated video here that explains it.) Diabetes no longer is quite the headache it was twenty – or even ten – years ago.

But realizing that I have exocrine pancreatic insufficiency (known as EPI or PEI) and learning how to take pancreatic enzyme replacement therapy (known as PERT) is a similar headache to diabetes in 2002.

With insulin, taking too much can cause hypoglycemia (low blood sugar). Taking too little can cause hyperglycemia (high blood sugar). Yet, with diabetes, you can measure blood glucose and see the response to insulin within a minutes-to-hours time frame. You can also use an insulin pump and an automated insulin delivery system to titrate and adjust insulin in real time.

However, for EPI, you need to take enzymes (that your pancreas doesn’t produce enough of) to help you digest your food. Your pancreas makes three types of enzymes: lipase, to help fat digest; protease, to help protein digest; and amylase, to help starches and carbohydrates digest. These are taken by mouth as a pill that you swallow. Together in one pill, it’s called “pancrelipase”, and it’s for pancreatic enzyme replacement therapy (PERT). (I’m personally bad about using pancrelilpase/PERT interchangeably, because PERT is faster to say and type, but it is possible to use standalone enzymes in PERT).

Because they are pills that you have to swallow when you eat, it’s hard to dose. Taking too little means you may have GI-related symptoms in the hours following the meal and feeling bad until the next day or so. Taking too much is expensive, although unlike insulin it’s rare to take “too much” and cause bad side effects (although possible at super high doses). There’s also the “pill burden”, because swallowing a bunch of pills is annoying and sometimes hard, both physically to swallow and to remember to take them throughout your meal.

You also can’t take more hours later if you forgot to take them or realize you didn’t dose enough for that meal. If you underdosed, you underdosed and just get to experience the symptoms that come with it. Sometimes, it’s not clear why you are having symptoms. Because there are three enzymes being replaced, it’s possible that the dosing was off for any one of the three enzymes. But again, there’s no measurement or feedback loop, or a sign that appears saying “you underdosed protease, take more next time”. The best you can do is try different sized meals over time with different doses of PERT, trying to reverse engineer your lipase:fat and protease:protein and amylase:carb ratios and continuously update them as you have new data.

It’s a lot of work, the feedback loop is slow, getting it “wrong” is painful physically and psychologically, and there are no vacations from it. Everything I eat, now that I have EPI, needs enzymes, and given the fact that I have automated insulin delivery to help manage insulin dosing, I am finding PERT to be a lot harder and more annoying (currently).

A comparison of dosing insulin and dosing enzymes. Insulin can cause hypo- or hyperlgycemia but there are tools (CGM and BG meters) and a feedback loop in diabetes. With enzymes, there is no fast feedback loop and underdosing is common. There is no ability to correct an underdose and there are multiple variables that can influence the outcome.

There’s no happy ending to this post, but this is one of the reasons why I am so interested in partnering with researchers to do research on EPI. There are a LOT of improvements that can be made, ranging from improving titration guidance of PERT to testing the efficacy of different over the counter enzymes to finding new technology that might begin to provide a feedback loop into EPI (either for short-term assessment or longer-term use for those who prefer it). If you’re someone interested in this type of research, please don’t hesitate to reach out (Dana@OpenAPS.org).

Feeling hunger for the first time in two years after discovering Exocrine Pancreatic Insufficiency (EPI or PEI)

Now that I’ve been taking pancreatic enzyme replacement therapy (PERT) for a month and a half for my newly discovered exocrine pancreatic insufficiency (EPI), I’ve not only discovered that the GI symptoms I had are gone, but I’ve also gained something back: the sensation of hunger.

For two years, I’ve struggled to eat. I found a breakfast that I could eat that was higher fiber (albeit nontypical American breakfast food) and kept me full for hours. So many hours that I didn’t feel like eating at lunchtime.

Essentially, I would eat breakfast and maybe one other meal, and occasionally a snack. Far from three meals. I learned quickly that eating just because other people were eating made things worse (worse symptom severity, plus gave me more symptoms), so I studiously avoided eating just because that’s what I had done in the past or that’s what other people were doing.

Figuring out I had EPI and starting to dose PERT was a relief. I could tell from symptom reduction that it was working. And within a week or so, I started to feel hunger multiple times a day! Now I’m more regularly eating three small meals a day, and sometimes more (especially on after long runs). My meals are more likely to be a little bit smaller due to how I’m titrating my PERT dosing, so that plus my activity levels plus actually digesting my food when I eat it means that I’m eating more often now than I have over the last few years.

The only downside is that my brain is VERY unfamiliar with the sensation of hunger, and despite knowing I will not starve or even be hungry for very long, there seems to be a switch after three minutes where I go from recognizing hunger and starting to think about doing something to having already passed the point of no return where my number one priority becomes eating.

The timeline of my body becoming hungry (0 minutes), my brain recognizing hunger (1 minute), thinking about eating (2 minutes), deciding to eat (3 minuntes), and then a flip switching and I go from wanting to NEEDING to eat as soon as possible.

I’m guessing this is what toddlers feel like, and I have a lot more empathy for their hanger now after experiencing this! And like toddlers, hopefully my brain re-learns how to deal with and moderate the feelings of hunger soon.

How I calculate fat and protein for pancreatic enzyme replacement therapy (PERT) dosing in homecooked meals

As I’ve been re-adding food items to my diet now that I know I have exocrine pancreatic insufficiency (EPI), I’ve been eating a lot of packaged foods with nutrition labels that are quick and easy to read. I’ve done a few meals that are takeout from a restaurant, and certainly the ones from chain restaurants with nutrition labels online are the easiest to enable me to optimally dose my PERT. (But not all restaurants, including my new favorite local taco place, have them and so I also do quite a bit of guesswork and experimenting.)

I’m now at the point where I can eat some onion and garlic and other FODMAPs again (yay!), so a lot of the homecooked meals I used to love to make – especially crockpot meals – are back on my list to try. This week I decided to try taco soup, a longtime favorite that involves cans of black beans, corn, dark red kidney beans, light red kidney beans, cooked ground beef, tomato paste, and ranch and taco seasonings.

One of the reasons I waited to cook large meals until this point in my EPI discovery experience was to save my energy for figuring out the fat and protein per portion size.

I’ve been creating a tab in my PERT enzyme tracking spreadsheet that’s labeled “ingredients”, and I’ve been listing commonly used ingredients (e.g. an egg, 1/4 cup of cheddar cheese, 1/4 cup of parmesan, 1 cup of milk) that I often add to my food and repeatedly need to add to my nutrient totals. I listed out all the ingredients for my taco soup recipe (see above), looked up the fat and protein and logged those, then added them all up for what one giant crockpot full of taco soup would be. That’s 44 grams of fat and 177 grams of protein.

(Side note – I found that Impossible ground beef tastes the same as ground beef and ends up being lower fat and protein. I was going to use it anyway, but that makes it easier to dose PERT by slightly reducing the fat and protein quantities.)

Then, after I cooked it (truly, set it and forget it), I scooped out a cup at a time to estimate the number of cups. For my current crockpot, it was about 12 cups.

So to figure out the taco soup individual serving size, I take 44 and 177 and divide each by 12, so it’s about 4 grams of fat and 15 grams of protein per cup of soup. I usually eat 2 cups at a time, so multiply by two to get the total of what I’m needing to dose PERT for, which is 8 grams of fat and 30 grams of protein. That’s *just* at my 1-PERT limit (at my current dosing)  for protein and well under my 1-PERT limit for fat (also about 30 grams), so I was able to cover 2 cups of soup with 1 PERT pill.

However, were I to add 1/4 cup of cheddar cheese, as I sometimes do, I’d need to add on additional enzymes to cover the protein. (It’s frustrating that I’m this sensitive to protein, enzyme-wise!)

This is also what I’ll do with potato soup (another crockpot favorite) and any other recipes that I make. Like diabetes tasks, I’ve found that splitting up the work whenever possible makes a difference, so I’ll list out the ingredients and look up the data and determine the total recipe counts separately from when I cook it, and from when I measure out how many servings there are and arrive at the final serving math.
An overview of the process of adding up fat and protein for all ingredients in a recipe; cooking and counting out the number of portions, then dividing the fat and protein totals by the number of portions (I use cups) to determine how many grams of each per serving and determine how much PERT to dose.
