Kicked Diabetes butt and ran my first ultra marathon and marathon yesterday

I thought I would share my thoughts on my first ultra yesterday, the Superior Trails Spring 50km. Not the running part, it was great but I worked on that for months before the race. I am really excited about how well my blood sugar was both before and after.

I used a pump and a CGM. I found a way to keep them stuck to me for over 6hrs I was out there and didn’t need to go to my backup site I had inserted, my spare site in my backpack or a syringe. My checklist seemed to help as it kept my mind on what to bring because luck would have it that if I forgot my spares like I did at my first trail marathon, I would have needed them and ended up pulling out.

The race started at 7am and I wanted to eat prior so I got up at 2:30am so that the bolus was mostly gone. In the past, the tail end of the bolus becomes very significant with the change in sensitivity I have. Normally under 0.1units wouldn’t be noticed. Then at 5am I set a temporary basal of 15%.

As expected, I started trending up going in but started the race at about 7.0mmol(125) and this continued for a bit and then started to drop. At about an hour in I started dropping a bit, this seems to be the magic time, and I ate a sport gel. This brought me back up and it kept trending up for a while. So I used a correction bolus of 0.2units and upped my basal to 20% of normal. This is where I wish my pump had a smaller increment than 0.025units/hr as it seems that somewhere between 0.150 and 0.175units/hr for the first few hours would have been perfect and later on, somewhere between 0.175 and 0.2 would have been. But I just kept bouncing my glucose between 6.0mmol and 10mmol after the initial little high of around 11mmol. I am not complaining at all. Although, I did notice that 7mmol/L seemed to be the sweet spot for how I felt.

Long story short, I was able to run my race, perform well and diabetes did not get in my way. It has kicked me in the butt enough times and I actually feel invincible now. I have no hypo’s or hyper’s much past 10mmol/L, it is possible to have decent control in tough situations.

As for the running part, I trained for about a 5hr race and had about 5hrs in me. I think I was top 20 until the base of Moose Mtn on the way back and between there and the finish I dropped 40 spots to finish 60th out of 177 people. I have never run more than 3.5hrs before so I cannot complain. I actually don’t feel beaten up or hurt much at all. I have hurt way more after a hard or really long run. I feel invincible almost. So maybe it is time to throw some speed back in the game and own a 5km or two. Get that time under 18min again.

  1. Congratulations on your accomplishment! (I meant to comment when you first posted this, but I hit the wrong button…) Anyway, THANK YOU for blogging about your T1D running experiences!!! I love running, have t1d, and have had quite a challenge finding others who have type 1 diabetes and run long distances — finding others who also do this and share their experiences helps me tremendously, and inspires me to go further, … and that even though diabetes can add an extra level of challenges to running long distances, that it doesn’t have to set your goal for you! (I’m actually visiting my sister and posting from her account — I’m Kristiann, not lwbail… just realized this won’t show as being written by me, and i can’t figure out how to change it! oops!) Anyway, Thank you and CONGRATULATIONS!!!!!
