...And 18 More
As the finale workout for our last peak week of training for Ironman Coeur d'Alene, I ran 18 miles early Sunday morning, about 14 hours after winding up our 124-mile ride. One of my favorite running spots in the Bay Area is Sawyer Camp Trail, which runs alongside Crystal Springs Reservoir. It is not uncommon to see deer along the trail, blue jays flying from tree to tree, and rabbits hopping out of the way. I felt surprisingly good and refreshed for the run--it must have been that sushi and miso soup the night before! I was pretty happy with the BG's as well. I fiddled around a lot with my basal rates, and would watch the resulting pattern with the Dexcom. Clearly there is a delay between a basal rate change and a change in blood glucose, but I was running for a long time! On the Dexcom, my BG's varied from about 125 to 148 while I was eating pretty steadily, 250-300 calories per hour. One of my revelations this weekend is that, even if I come in with a basal rate that is too high, it won't affect me for more than an hour or so. This is not the same for boluses, however, which seem to last with me for many hours.
