Ok, I’m not really sure how to start this! But some of you may remember that I ran a half marathon not too long ago! And that was incredibly hard, but also incredibly fulfilling. So I figured I’m halfway there, and now is the time (before rotations start), and I really wanna do this, so I’ll be running my first marathon in the spring!!!
I wanted to start a thread because I thought it’d be fun to look back on progress and such. I think I’ll post some general BG trends and solutions as I’m working through them in case anyone has feedback or in case that’s helpful for anyone else. I’m super happy to hear feedback on running or BG management!
I guess general overview before I get into anything else: I use the tandem t-slim x2 with basal IQ and Fiasp. While on runs, I tend to set basal 40-60% depending on where my BG is at and what kind of run I’m doing. I use swedish fish or transcend gels for getting carbs/treating lows while running. I try to target 90mg/dL while running.
Most of my runs are in the morning before class, and most of my runs are inside on the treadmill. Some runs do end up in the afternoon. I like to do my longer runs outside, weather depending.
Ok! First notable trend I’ve found is a consistent spike within my first 15 min of running - regardless of when I start running (morning or afternoon), if I have any or no carbs on board, regardless of what kind of run it is, regardless if I’ve had any or no suspends from basal-IQ prior to starting, regardless if I’m in a time of insulin resistance during my hormonal cycle. (I think that’s all the variables I’ve looked at and have ruled out ) So, that leads me to believe that running (or thinking of running) is just kind of stressful and causes some adrenaline to get pumped out, right when I start running or just prior to starting to run. So, my solution for this early spike is to bolus before starting to run (I think ~15min or 20min is the right time for me) but I’m still working on figuring out the right amount and timing on it. This insulin does seem to prevent my spike, but I think it may start to drop me 25-30min into the run. I am thinking of playing around with a more substantial basal drop and the timing on that.
Wow, sorry for so much text right up front! But anyways, welcome to my marathon thread. I’m so excited to continue to work towards crushing my first marathon and sharing some thoughts about it with you along the way!!!
