I still plan on posting the skiing post that’s been in my drafts folder for about four months now. Maybe I’ll try to finish it up this week . . . supposing I can drag myself away from my MATLAB diabetes app programming. In the meantime, I thought this blog post from Olympic Nordic skier (and BA-D-MoFo) presented an interesting idea about insulin management during endurance events.
I have been asked several times what my insulin dosing was for the 50k in Tahoe this Spring. For most races I run the same amount of insulin from the start to finish of a race but the 50k is a different beast. Because of the long duration of the event I completely deplete my glycogen stores. Thus I need less insulin in my blood as the race progresses. I started the race with a high (for me) basal rate 0f 0.8 units per hour in order to keep my topped off glycogen stores from raising my blood sugar. For the second hour of the race I had my OmniPod insulin pump programmed to lower my basal rate to 0.6 units. At two hours my Pod lowered the basal rate once more to 0.4 units which is the dose I finished on. Throughout the race I took 13 planned four ounce feeds. I started the race with a blood-sugar of 170 and finished at 140.
As always, your diabetes
may will most definitely vary, and you shouldn’t ever just copy what someone else does. Nevertheless, it’s another thing to think about while trying to find what works.
