I'm impressed. I have to hoover up calories to keep from boinking. Yesterday's ride was particularly tricky. Since the start was almost all downhill, I didn't feel the need to eat until 20 minutes up the climb, and by then it is too late. I should been eating a lot on the way down from Yacqui pass (what a beautiful, gentle road to bike down)! I don't see how you can do a ride like this without refueling more! But then again you do a lot of longer rides, so you've fortified yourself.
