On Sunday I rode a solo century on Cape Cod. It was pure sun and through the day warmed up to about 85º F and 75-80% humidity. I was going fine for first 75 miles or so, but the last 25 mi. were hell. That last 25 mi. my heart rate was about 15-20 bpm below where it was earlier in the day, and my power dropped about 20-30W with it. I wasn’t totally delirious, but was worried a bit about making it home. It was hard to tell, but it also seemed like I wasn’t sweating as much toward the end.
I’m at 240 ftp and was holding around .64 IF for most of the ride (until it started declining with HR and power). So I don’t think it was a pacing issue. I’ve done this distance before, even this route before.
Fuel wise, over 6.5 hours moving time I had:
- (pre-ride oatmeal)
- The carbs from 2 bottles of Skratch
- 2 Clif bars
- 1 Skratch bar
- 2 packages Skratch chews
- 1 bacon and egg on ciabatta sandwich
- 2x22oz. bottles Skratch
- 4x22oz. bottles SIS electrolyte mix
- 1x12oz. Coke
