Reasons to “DIY” or Self-Organize Your Own Solo Ultramarathon or Ultra Run

by Dana Lewis

I’ve now run two ultramarathons (both happened to be 50k races, with a race report for the second race here), and was planning my third ultrarace. I had my eye on the 50 mile (50M) version of the 50k I ran last year. It’s on a course I adore – a 6 foot wide crushed gravel trail that’s slightly uphill (about 1,000 feet) for the first 30 miles and then downhill at 2% grade for the remaining 20 miles. It happens to be close to home (hour and a half drive to the start), which helps for logistics.

I started training for the 50M weeks after my 50k this year, including talking my husband into taking me out to run some of the segments along the first 25 miles of the course. I’ve done the back half of the course several times through training and racing the 50k, and I wanted to check out each of the earlier segments to get a sense of what trail bathrooms existed on the course, make notes about milestones to watch for at various distances, etc.

After the first training run out there, when I started talking goal paces to get through the first and main cutoff at mile 30 (cutoffs got progressively easier from there, and even walking very slowly you could finish if you wanted to), my husband started to suggest that I should just run the course some other time on my own, so I didn’t have to worry about the cutoffs. I told him I didn’t want to do that. The cutoffs are a good incentive to help me push myself, and it’s worth the stress it causes in order to try to perform my best. (My target pace would get me through a comfortable 15 minutes before cutoff, and I could dial up the effort if needed to achieve cutoff). However, he suggested it another time and pointed out that even when running an organized race, I tend to run self-supported, so I don’t really don’t benefit as much from running in a race. I protested and talked again about the camaraderie of running when everyone else did, the fact that there were aid stations, the excellent search and rescue support, the t-shirt, the medal, the pictures! Then out loud I realized that I would be running at the back of the pack that I would miss the pictures at 25 miles because the photographer heads to the finish before I would get there. And they stop finish line pictures 3 hours before the end of the race. (Why, I don’t know!) And so I’d miss those photos too. And last year, I didn’t partake in the 50k staffed aid stations because I couldn’t eat any of their food and didn’t want any extra COVID exposure. Instead, my husband crewed me and refilled my hydration at two points on the course. The un-staffed aid stations didn’t have the plethora of supplies promised, and one race report from someone near the front of the pack said they were low on water! So it was a good thing I didn’t rely on the aid stations. I didn’t wear the tshirt last year, because it wasn’t a tech tee. Medals aren’t that exciting. So…why was I running the organized race?

My only remaining reasons were good search and rescue (still true) and the motivation of signing up for and committing to running on that date. It’s a commitment device. And my husband then smashed that reason, too, by reminding me that the only commitment device I typically need is a spreadsheet. If I decide I’m going to work toward a goal, I do. Signing up doesn’t make a difference.

And to be fair, he crews me whether it’s an organized race or not! So to him, it makes no difference whether I’m running an organized race or a self-organized long ultra.

And so I decided to give it some thought. Where would I run, if I could run anywhere in an hour’s distance from home? Do the same 50 mile course? Was that course worth it? Or was there somewhere closer to home where I could run that would be easier for my husband to crew?

He suggested running on our “home” trails, which is a network of hundreds of miles of paved trail that’s a short walk away. I immediately scoffed, then took the suggestion seriously. If I ran “from home”, he could crew from home and either drive out or e-bike out or walk out to bring me supplies along my route. If the park trail bathrooms ended up getting locked, I could always use the bathroom at home (although not ideal in terms of motivating myself to move quickly and get back out on the trail). I’d have a bigger variety of fueling options, since he could microwave and bring me out more options than if it had to be shelf-stable.

The list of benefits of potentially doing my own DIY or self-organized ultra grew.

(And then, I broke my toe. Argh. This further solidified my willingness to do a DIY ultra, because I could train up until when I was ready, and then run my distance, without having to choose between a non-refundable signup and not running or risking injury from running before I was ready.)

Eventually, my plans evolved (in part due to my broken toe). I was originally going to DIY a 50M or 100k (62M) over Labor Day weekend, recover, then re-train up and run a DIY 100 mile (100M) in late October or early November. When I broke my toe, I decided to scratch the “test” 50M/100k and just train and run the 100M, since that was my ultimate goal distance for the year.

Here are the pros of running a DIY ultra or a “self-organized” ultra, rather than an organized race with other people:

  • For me specifically, I have better trail options and route options. I can run a 95% flat course on paved, wide, safe trails through my local community.
  • These are so local that they are only a few minutes walk from my door.
  • The location means it’s easy for Scott to reach me at any point. He can walk out and bring me water and fuel and any needed supplies when I complete a loop every 4 or so hours. If needed, he could also e-bike out to bring me anything I need if I ran out or had a more urgent need for supplies. He can also drive out and access the course every half mile or mile for most of my planned route.

    This also means I have more fuel options that I can prepare and have for Scott to bring out. This is awesome because I can have him warm up ¼ of a ham and cheese quesadilla, or a corn dog, or sweet potato tots, or any other fuel options that I wouldn’t be able to use if I had to rely on pre-packed shelf stable options for a 30 hour race.

    (Note that even if I did an organized race, I most likely still wouldn’t benefit from aid station food. In part, because I have celiac and have to have everything gluten free. I also have to watch cross contamination, so a bowl of any kind of food that’s not individually packaged is something that’s likely contaminated by gluten. COVID has helped reduce this but not completely. Plus, I have diabetes so I need to be roughly aware of the amount of carbs I’m eating to decide whether or not to dose insulin for them, given what is happening to my blood sugar at the time. And, I have exocrine pancreatic insufficiency (EPI) which means I have to dose enzymes for everything I eat. Grazing is hard with EPI; it’s easier to dose and eat the amount that matches my enzymes, so pre-packaged snacks that I know the carb and fat and protein count means I know what insulin I need and what enzymes I need for each set of “fuel”. Guessing carb counts or enzyme counts in the middle of the night while running long distance is likely not going to be very effective or fun. So as a result of all that – pre-planned food is the way to go for me. Related, you can read about my approach for tracking fuel on the go with a spreadsheet and pre-planned fuel library here.)

  • There is regular public bathroom access along my chosen route.
  • I’ve designed out and back laps and loops that have me coming back by my start (remember, only a few minutes walk from home) and that make it so I am passing the bathrooms multiple times on a regular basis in case I need them.

    These laps and loops also make for mentally smaller chunks to tackle. Instead of 100 miles, I’ve got a ~24 mile out and back, a 13 mile loop, a 16 mile out and back, a repeat of the 13 mile loop, repeating again the 16 mile out and back followed by the 13 mile loop one more time, and then a quick 5 mile total out and back (so 2.5 out and back). These are also all routes I know well, so mentally finding waypoints to focus on and know how far I’ve gone are a huge benefit for mentally breaking down the distance into something my brain and body “know”.

  • There are no cutoffs or pace requirements. If I slow down to a 20 minute mile (or slower)…well hey, it’s faster than I was walking with my hands-free knee crutch a few months ago! (I rocked anywhere from a 45 minute mile to a 25 minute mile).

    There’s no pressure to go faster, which means I won’t have pressure to push my effort, especially at the start. Hopefully, that means I can maintain an “easy”, even effort throughout and maybe cause less stress to my body’s hormone systems than I would otherwise.

    The only pressure I have will be the pressure I put on myself to finish (eventually), which could be 26 hours or could be 30 hours or could be 36 hours or even slower… basically I have to finish before my husband gives up on coming out to refuel me!

  • And, once I finish, it’ll be ‘fast’ to get home, shower, refuel, and be done. This is in comparison to a race where I’d have an hour+ drive to get home. I’ll need to walk home which might actually take me much longer than that after I’ve ambulated for 100 miles…but it should hopefully be shorter than an hour!
  • Finally, the major benefit is flexibility. I can set my race date for a weekend when I’ve trained enough to do it. I can move it around a week or two based on the weather (if it’s too cold or too rainy). I can even decide to move it to the spring (although I’d really love to do it this year).

Here are some of the cons of running a DIY ultra or a “self-organized” ultra, rather than an organized race with other people:

  • Theoretically, it would be easier to stop because I am so close to home. I haven’t committed money or drive time or dragged my husband to far away places to wait for me to finish my run. (However, I’m pretty stubborn so in my case I think this is less of an issue than it might be for others?)
  • Yet, out and back loops and the route I’ve chosen could get monotonous. I chose these loops and the route because I know the distance and almost every tenth mile of the route super well. The first 6 miles of all the laps/loops are the same, so I’ll run those same 6 miles repeated 7 times over the course of the run.
  • I won’t have the camaraderie and knowledge that other people are out here tackling the same distance. I’m a back of the pack runner (and celebrate being places from last the way most people celebrate places from first!) and often don’t see anyone running after the start…yet there’s comfort in knowing I’m one of dozens or hundreds out here covering the same course on the same day with the same goal. I do think I’ll miss this part.
  • There is no one to cheer for me. There’s no aid station volunteers, fellow runners, or anyone (other than my amazing husband who will crew me) to cheer for me and encourage me and tell me I’m moving well.
  • There’s no medal (not a big deal), t-shirt (not a big deal), or official finishing time (also not a big deal for me).
  • There’s no cutoffs or pace requirements to motivate me to keep pushing when things get hard.

All in all, the benefits pretty clearly outweigh the downsides – for me. Again, I’m a back of the pack super slow runner (in fact, I typically run 30 seconds and walk 60 seconds throughout my whole race consistently) who can’t eat aid station food (because celiac/EPI makes it complicated) coming off of a broken toe injury (which messed up my training and racing plans), so my pros/cons lean pretty heavily toward making a DIY/self-organized solo ultra run an obvious choice. Others might have different pro/con list based on the above variables and their situations, but hopefully this helps someone else think through some of the ways they might decide between organized and un-organized ultramarathon efforts!

Reasons to "DIY" or self-organize your own ultramarathon run

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

by Dana Lewis

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

What is in my running pack for running ultramarathons or training for a marathon

by Dana Lewis

After three years of using a multi-purpose activity backpack as my running pack, the strap connector broke, and I had to find and re-stock a new running pack. I use a running pack for when I’m doing long runs for marathon or ultramarathon training.  I ended up pulling everything out of my old backpack and evaluating whether I still wanted to carry it on every long run. For the most part, everything got moved over to the new pack. There were a few cases where I had excessive duplicates (more on that below and why) where I ended up reducing the quantity. But everything else made the list for what I carry with me on long runs every single time.

  1. Hydration – via a camelbak or other bladder with a hose (example). I prefer straight water in my hydration pack and to separately manage electrolytes and fuel separately. The bonus of just having water is it’s easier to clean the hydration pack after each run!Tips: put ice cubes in your bladder and fill it with cold water. Cold water is awesome for long, hot runs in the sun. Also, my old hydration pack had an insulated compartment that kept the ice water cold for hours. My new running vest does not, and in fact has holes in the back for air flow that also means the heat from my back melts my ice pretty fast. To work around this in the new vest is to slide the filled hydration bladder into a padded mailing envelope that’s open at the top. It’s not quite as insulated as true insulation, but it protects the bladder from some of the heat coming off of your back and it probably stays cool 60% instead of 20% as long as before, which is a huge improvement.Extra tip: use a Qtip or similar to clean out the mouthpiece of your hose every few runs!
  2. Diabetes backups  – this means things like a backup insulin pump site. On long unsupported runs, it can also mean my blood glucose meter. (I wear a CGM so I don’t always take a meter along on runs unless it’s in an unsupported area where I don’t have easy crew access or support within a few miles). I’ve had several runs where my pump site has stopped working or ripped out, so having a backup pump site is just as necessary as having bandaids.The other source of backups is extra low carbs, e.g. sugar in case my blood sugar goes low. I usually keep a stash of carbs in my shorts pocket, but I also keep extra in my backpack in case I run through everything in my pocket. This is in addition to regular food/fuel for ultrafueling, it has to be faster-acting glucose/sugar that can more quickly fix a dropping or already-low blood sugar level.(This is one of the places I mentioned where I had excessive duplicates. I have continued to add extra to my backup stashes, and ended up with well over 100+ grams of “backup” carbs just in case. I ended up cutting down the total amount of carbs to closer to ~50 grams instead.)

    Emergency backup carbs maybe don't need to be 100g worth

    You can read some more about my strategy for running with diabetes here.

  3. Baggie with extra socks – I always carry a pair of extra socks, although I’ve never needed them in a normal training long run, I did end up using them in my 50k that involved crossing a river up to my knees five times.
  4. Bandaids – Just like hiking, but I carry bandaids in case of bleeding cuts or scratches or worse, blisters on my heels, feet, or toes. I carry some that are blister-style and some regular style, smaller ones and larger ones, all the way up to large multi-inch squares that can cover the backs of my heels if I don’t already have them covered.More recently, I also started carrying small squares and strips of kinesiology tape for the same purpose. I originally did kinesio tape strips in case my knee needed some extra support, but I’ve found the kinesio tape also works well to cover my toes or backs of my heels in lieu of bandaids for blister prevention. For fixing blisters, I have to dry my feet really well or the kinesio tape doesn’t stay well or easily rubs off; so I tend to cover the toes that blister frequently as well as my heels prior to my runs so they’re less likely to generate blisters and require fixing mid-runs. I get a large roll of kinesiology tape (example) and cut it into smaller pieces as needed for all of these uses cases.I also keep at least one mini individual packet of antibiotic ointment (example) in the baggie as well.
  5. Lubrication – I carry a lubrication stick (Squirrel Nut Butter, because it works for me and is easy to reapply) to making sure between my thighs and other areas don’t chafe. When I sweat a lot, I often have to reapply every few hours to my thighs. While this can also be accomplished by carrying dabs of vaseline or your preferred lubrication in a baggie, the SNB stick is lightweight and I don’t mind carrying it so it’s easy to reapply and the hassle doesn’t prevent me from wanting to prevent chafing.
  6. Stuff to fix GI problems – it’s common to have GI issues when running, but I also had a two-year stretch of known GI issues that ultimately turned out to be undiscovered exocrine pancreatic insufficiency. During this time, I always carried individual Immodium and GasX in case I needed them.
  7. Electrolyte pills – I prefer to measure and track electrolytes separate from my hydration, so I use electrolyte pills (example) that I swallow on a scheduled basis to keep my electrolyte levels topped off. I’ve tried chew kinds (but they make me burp), so I stick with a baggie full of electrolyte pills. I bring extra just in case I drop some, but I generally eyeball and count out to make sure I have enough for each super long run.
  8. Any medication you need during the run – For me, that includes enzymes for fuel because I have exocrine pancreatic insufficiency and I need enzymes to help me digest any of my fuel. I have expensive, larger dose prescription pills that I usually use for meals, but it would make running even more expensive if I had to use a $9 pill every 30 minutes for a fuel snack. Luckily, there are over the counter versions of enzyme pills (more about that here) that are single-enzyme or multi-enzyme, that are more in the ballpark of $0.35 per pill, and I have a baggie of both kinds that I use to cover each snack.
  9. Fuel or snacks – A lot of ultra runners use gels, but I have been experimenting with ‘real’ foods. Basically, anything that’s around ~20g of carbs and less than ~10g of fat and 5-10g of protein that I like to eat. So far, that list includes chili Cheese Fritos, yogurt covered pretzels, peanut butter pretzel nuggets, beef sticks, Honey Stinger Stroopwaffles (the gluten free kinds – beware that only some of their flavors are GF!), mini date or fruit bars, fruit snacks, sweet potato tots, ¼ of a ham and cheese quesadilla, ¼ of a PBJ sandwich, a waffle, mini PayDay bars…. Noting that all of these are gluten free versions or are naturally gluten free, because I have celiac disease. I do a lot of work in advance to test these snacks carefully on training runs before I commit to using them repeatedly throughout longer runs so I know my body likes them during runs as well as other times. I only take the fresh/hot snacks (sweet potato tots, quesadilla etc) and eat those at the start or when my husband re-fills my pack for me mid-run, so I don’t have to worry about them spoiling. Everything else is shelf stable so when I pack a few more than I need per run and leave some in my pack, they’re not an issue to sit there for weeks until I manage to eat them in my rotation of snacks on a future run.
  10. Miscellaneous other supplies – car keys, house keys, hand sanitizer, a mask for going into trail bathrooms, and a battery and cord for charging my phone.

Phew. That’s a lot of stuff. And yes, it does end up being more supplies and more weight than most people carry. But…I use pretty much everything in my pack every few runs. Stuff happens: pump sites fall out, blisters happen, chafing happens, GI stuff happens..and I’ve found that training and running with a little extra weight in my pack is worth having the proper supplies when I need them, rather than having to end runs early due to lack of preparation or minor supplies that would enable me to keep running.

Every time I go out for a run, I add the requisite amount of snacks, enzymes, electrolyte pills, and hydration for the run. Any time I come back from a run and I have depleted a supply off of the above list – such as using my backup pump site – I immediately go and refill that supply so I don’t have to remember to refill it prior to the next run. Keeping the above supplies topped off and ready to go always in my backpack means they’re always there when I need them, and the peace of mind of knowing how I can handle and that I can handle these situations while running is priceless.

Note: previously I was using a backpack, because it was $30 and for my running it was good enough. However, when the strap broke, I looked to buy the same backpack again and it was $60. It was fine for $30 but if I was going to double the cost, I decided to research alternative running packs and vests. Vests seem to be more common in ultrarunners, so I looked for those, although they’re a lot more expensive (often $125-200). I was disappointed with how small of a volume some of them held, or they were just ugly. I liked the look of a purple one I found that came with a 1.5L bladder….but ugh. I fit a 3L bladder in my previous backpack and typically fill it 2-2.5L full as a baseline, and all the way up for a longer (6h+) unsupported run. I decided to risk getting this vest even though it was smaller and try putting my larger 3L capacity bladder in the new vest. (Luckily it was on sale for $90 at the time  which made it a little less annoying to buy compared to a $150 one.) The bladder does fit, but it sticks out the top and hits the back of my neck if it’s all the way full (3L). So for the most part, I’m filling the 3L capacity bladder about 2L full (and as noted in this post earlier, putting it inside an insulated envelope to help retain the cold for longer), and that works for me.

One thing I do like a lot from my new running vest is the front pockets. My old backpack I had to partially take off and twist around me in order to get snacks out. With two large front pockets, I can fit several hours of fuel in there so there is no twisting involved to get my fuel out, which is helping with my goal to fuel every 30 minutes. I do wish there was a separate smaller pouch – my old backpack had a small old school flip phone size “cell phone” pocket that I used to keep my baggies of enzymes and electrolytes in. Right now, I just have those baggies floating around the top of those pockets and it’s fairly easily to grab and pull out the right baggie, but I’m toying with adding some kind of small strap-on holster/pouch to the shoulder just for enzymes so I don’t have to worry as much about them jostling out when my pockets are completely full of snacks. But otherwise, these front pockets are overall a nice improvement.

Stigma and the impact on people with chronic illnesses

by Dana Lewis

I have a new thing, and I didn’t want to talk about it. In part, because of stigma. Mostly, because of stigma.

Stigma has played a huge role in how I have responded to my own chronic autoimmune diseases for almost 20 years, in fact. I’m incredibly disappointed that not much has changed in all this time.

When I was diagnosed with type 1 diabetes almost 20 years ago, I was very aware of the stigma against people with any type of diabetes. I grew up in Alabama. People with diabetes were perceived by society to be lazy, out of control of their own behaviors, and any complications or outcomes were their own fault.

It wasn’t – and isn’t – their fault. The tools and technologies (not much technology then) did not give people a chance at good or great outcomes. The tools and technologies failed people. Yet, people and their behaviors were and often still are blamed, shamed, and treated poorly in society and in medicine and the healthcare system.

The first day I was diagnosed and sent from my primary care doctor’s office to the pediatric endocrinologist, I was scared. Diabetes in society was presented to me as amputations and kidney disease and other not so great things. I didn’t know anyone with type 1 diabetes. And when the pediatric endo came into the room for the first time and said, “Don’t worry. We can get you an insulin pump, it’ll be great!” my reaction was: absolutely not. An insulin pump will be a visible label that I have diabetes. Instead of a chance of being blamed, shamed, and treated badly – I will almost certainly be labeled, blamed, shamed, and treated badly. No, thanks.

And so I didn’t get on a pump (at first). It wasn’t until I realized that a pump would give me freedom, to sleep in and not have to wake up and eat a pre-allotted amount and take insulin, that I decided the personal freedom was worth the labeling, dirty looks, blame, shame, and negative treatment.

And I regret it. I regret how stigma shaped my reaction to possible tools and technology that would aid me. I’ve strived ever since to not let that factor into my choices.

But last week, I realized stigma was still playing a role. I have a new thing, and I rationalized my choice not to blog about it because it’s a well-known thing, and as a newbie, surely I didn’t have anything to add to the public discourse about this thing. Information is available about this new thing, and I wouldn’t be adding anything new. What did I have to say that hasn’t been said before about this common topic?

But after a few days, I realized my decision to not blog about my experience was also driven by stigma and fear of how I’ll be treated when I share publicly that I have YetAnotherThing on my list of things I’m managing. It’s an autoimmune thing, again. It’s not “my fault”. It’s not at all in my control.

Because my immune system is too strong for my body to handle, I have not one, not two, but now three autoimmune things. (And 4 things total, but exocrine pancreatic insufficiency is possibly not an autoimmune thing so I leave it off the list even though it’s on my overall list of things I’m managing.)

Like people with physical or visible disabilities, having a chronic disease and talking about it publicly gives people the feeling that they can publicly shame and blame me “for my own good”. Or hypothesize on what I’ve “done wrong” to get to this point. Or to “suggest” things I can do to better manage. Often, these things are scientifically wrong. (Note: this is why ‘cinnamon’ is a joke for people with type 1 diabetes. There is no cure or treatment for type 1 diabetes other than taking insulin for the rest of our lives. Cinnamon does not cure diabetes, yet it and other things are presented to people with diabetes as “alternative” methods that would in fact, kill me if I relied upon those and stopped taking insulin.)

I dislike this. I dislike the fact that being open about what I’m dealing with, in order to possibly help other people also dealing with the same thing or identifying gaps in the healthcare system, invites judgment and all of this commentary. Let me be clear: I do not invite that. Ever. Not now, not in the future. Not about diabetes, not about celiac, not about exocrine pancreatic insufficiency, and not about my new thing. I’ve noticed more and more other advocates writing in their tweet threads or their blog posts “This is not soliciting advice or suggestions”, because so often we ARE bombarded with “advice” or “suggestions” that are unsolicited, and like I mentioned above, possibly dangerous if not outright deadly.

I don’t have answers. I can’t fix the stigma in society. The best I can do is perhaps write about it and talk about it and help shine a light on the fact that it 100% does impact people. It prevents other people from seeking healthcare when they need it. It prevents people from sharing and processing their feelings, or reaching out for help when they need it. It causes harm. And we all need to do better as a society.

So I am sighing a lot, and writing this blog post first so I can process my feelings that are blocking me from writing the next blog post. The one with scientific information and citations as well as an articulation of my experience and situation, in hopes that one day someone on page 18 of a search engine will find it when they need it. It’s not for everyone.

But as always, I think that if it eventually helps one person, then it’ll be worth it. It’ll be worth the stigmatizing response that some people will have now and in the future when they realize I am someone living with multiple autoimmune diseases. I hope. It’s always my hope. I’ve had this tagline on my email ever since I first had email, and I still believe it’s true today which is why I wrote this blog post and am now turning to writing the next one:

“Doing something for someone else is more important than anything you would do for yourself.”

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

by Dana Lewis

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

by Dana Lewis

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)

by Dana Lewis

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

Click here to make a copy of my spreadsheet.

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

by Dana Lewis

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!

The multivariable equation that is running with type 1 diabetes, celiac disease, and exocrine pancreatic insufficiency

by Dana Lewis

I’ve written in the past about running with type 1 diabetes. I’ve tried running fasted, which works well in one sense because I have no extra insulin on board. I’ve modified my strategy further to run 2 or more hours after breakfast, so I have fuel but don’t have (much) IOB. But as I’ve extended my forays deeper into longer distance ultrarunning, and as I learned I have exocrine pancreatic insufficiency (EPI), running is getting a little more complicated.

For past thoughts on T1D running, here’s my post on running fasted and thinking about IOB. I also wrote more here last year about marathon and 50k ultramarathon training and how I use small doses of carbs to “correct” for dipping blood sugars. Last year, my body didn’t seem to need or want much additional fuel, so I didn’t force it. Part of that was likely a symptom of my undiscovered EPI. Now, however, that I am taking enzymes for pancreatic enzyme replacement therapy so I can digest what I eat, I have more energy (because my body is actually using what I eat), but I also get hungry and seem to need more fuel while running. But everything I eat needs enzymes to help me digest it, even things that I eat while ultrarunning.

So…it’s complicated to run with type 1 diabetes and micromanage insulin and carbs to manage blood glucose levels; and I’m limited in my fuel choices because I have celiac disease; and now I have to also carry, titrate, and dose enzymes for any fuel that I eat on the run as well.

Oh, and like insulin, the timing of enzymes matters. But there are no studies on enzyme digestion and how that changes during exercise, let along endurance activities like ultrarunning. So I am running in the dark, so to speak, trying to figure out things myself as I go along.

Here is more detail about what I’m doing and why I’m constantly running multivariable equations in my head while training for a 50k, 50 mile, and maybe even 100 mile run later this year:

First and foremost, managing blood sugar levels comes first.

I wear a CGM, so I can see how my blood sugar (BG) is changing during the run. I have a pump, so I can make any changes to insulin dosing. I also have an open source AID system (OpenAPS), so before running I set a higher target which tells the system not to give me as much insulin as it would otherwise. (It also does an awesome job with post-run insulin sensitivity changes! But that’s another post.) As I’ve previously written about, reducing insulin on board (IOB) when I know I’ll be running is the important first step, so I don’t have to start taking carbs and treating a low at the start of my run. Usually, my open source AID and I (by giving it a temporary target) do a good job getting me to my run start without much IOB, and ideally somewhere around 120-130 mg/dL.

From that level area, I can see rises and dips in BGs and dose accordingly. I carry easily dissolving small mint-like candies that are a few carbs (3-4g), or Airhead minis (8g of carbs), and with any dip below 120 or recurring drop that’s not coming up after 15 minutes since my last carb, I take more. These are pretty much straight sugar, and my body seems to do ok with absorbing carbs without enzymes, as long as there is no fat or protein involved.

However, with ultrarunning it’s generally considered to be ideal to proactively be consuming fuel to balance out the energy that you’re burning. Again, this is where I’m less experienced because for the last years, my body never wanted fuel and I did ok. However, now I seem to need fuel, so I’m working on figuring this out because food typically has some fat and protein, and I have to dose enzymes for it.

I carry a baggy with some single-enzyme (lipase) pills and some multi-enzyme (lipase for fat, amylase for carbs, and protease for protein) pills. I carry carefully measured single-serving snacks that I know the fat and protein quantity of. For each snack, I might need 1-2 enzyme pills of various sorts.

Timing matters: I can’t take enzymes and then snack slowly for 30 minutes. To eat slowly, I would need to take enzymes every 10-15 minutes to match the speed of eating so it will ultimately be there to help the food digest.

But, more carbs/food at once has an effect on how I feel while running and also to my BGs. I’ve tried to find things I love to eat running and can eat within 5 minutes – even while running 30 seconds and walking 60 seconds repeatedly – that are also less than 1-2 enzyme pills worth of fat and protein and aren’t too many carbs at once. These may be 15-20g carb snacks which means a bigger impact to my BG levels, and I may need to even do a small bolus (give insulin) for what I am eating. The challenge again is that food can hit BGs in about 15 minutes but it takes ~45 minutes for insulin activity to peak. And, during exercise, I’m more sensitive to insulin than I normally am. There’s no magical calculation to know how much “more” sensitive I am in the midst of a run, so I have to guess and thread the needle between not giving too much insulin that would cause a low BG but giving enough so I don’t spike above 180 mg/dL, which is what makes me feel icky while running.

Preferably, and very personally, I’d like to float up and down between 120-140 mg/dL or 130-150 mg/dL, which is higher than BGs usually hang out for me without exercise (remember: open source AID!), but is high enough that I have buffer against a low, so if I suddenly dip and I haven’t looked at my BGs in 15 minutes, I can usually still carb up and prevent an annoying low. (Lows matter even more on runs because they slow me down physically, which is usually not what I’m going for.)

It doesn’t always work that way. Sometimes I undershoot the insulin because I’ve miscalculated my effort running, and my BG drifts high and I have to decide whether or not to correct further. Other times, I overshoot (or have increased my run effort and didn’t take that into consideration) and cause BG to dip or dive toward low. Then I have to carb up but hopefully not so much that I cause a high.

My priority list therefore is: manage BGs, take in fuel, try not to over or undershoot on insulin for the fuel or overshoot carb corrections for drifting BGs, plus remember to take enzymes for the fuel and dose the right amount, plus stay on top of my electrolytes. Oh, and keep run-walking.

And along the way, I am also trying to document and learn whether the absorption of enzymes changes during different intensities or lengths of exercise; whether these over the counter enzymes are reliably measured enough for small snacks, and whether my personal ratios for fat and protein are any different during exercise the way my sensitivity to insulin changes during exercise.

It’s a lot of work. Plus, the pre-work that goes in to finding, measuring, and preparing foods that I think I want to eat during the run!

My current short list of single-serving snacks that I can tolerate while doing long runs includes: 8 gluten free peanut butter pretzel nuggets; 1 serving of chili cheese Fritos; 6 gluten free yogurt covered pretzels; and 1 gluten free stroopwaffle. Each of those is 15-20g of carb, 1-2 enzyme pills, and some of them have a bit of sodium. (I’m also fairly sensitive to sodium so I take electrolyte pills every 30-45 minutes while racing, but I’ve realized the extra fueling with a bit of sodium makes it so I don’t have to take the electrolyte pills every 30 minutes like I used to.)

When I build up to my longer (50 mile or maybe 100 mile ultras, if I get there!) runs, I’m also going to need additional “real food” options, as I doubt I will be able to or want to eat stroopwaffle and Fritos for as long as the run will take. This is just a theoretical list, but it includes tomato soup (sodium and warm liquid!), instant mashed potatoes (soft and not much chewing involved), grits and oatmeal (not together, but same reason as mashed potatoes). These all luckily also happen to be lower in fat and protein, which means easier to digest (in theory), and I am less likely to have better error margins against getting the enzyme dosing wrong given the small amounts of fat and protein.

What it comes down to is that running with type 1 diabetes is a giant constant personal science experiment. Celiac makes it more work, but also removes some of the variables by limiting what I can to eat: as at races I can’t eat out of any open bowl or package due to cross contamination concerns, and reading packages takes time, so it’s way safer to just eat what I bring myself. Having EPI on top of that means mastering the art of digesting food with pancreatic enzyme replacement therapy, which is its own special form of science experiment.

There’s a lot of variables, a lot of science, and a lot of learning going on every time I go for a run. Doesn’t it sound fun?!

Multivariable Equations: Running with Type 1 diabetes, celiac disease, and Exocrine Pancreatic Insufficiency

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

by Dana Lewis

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.
