One goal of last Saturday's 'Round GSO Epic was to gauge my fitness. The second, and perhaps more important, was to confirm that my approach to managing my nutrition, hydration and blood glucose is working.
Using an insulin pump simplifies the latter task. I've determined that a temporary basal rate of 80% yields good results. However, I was curious to see how this would pan out on a longer ride, where the need to maintain a steady intake of carbohydrates is greater than on a 30-40 mile ride.
Eating while on the run (or rather, the bike) isn't something that comes easy to me. On shorter rides I prefer to get my carbs from liquids -- usually Hammer Heed. I started with two bottles of Heed, which I drank during the ride. At stops I refilled my bottles with Gatorade. I drank a total of five bottles during four-plus hours on the bike.
I supplemented this with a couple of Hammer Gels (banana!), a small package of Fig Newtons, a banana, and one french fry. Not much for an 80 mile ride, but surprisingly my bG stayed within a normal range throughout the ride.
