I believe in the body wisdom... when you're not cluttered up w/ a lot of sugar and processed foods, I think your body pretty much tells you what you need to eat. When I'm on a long ride, I start to crave a tuna melt-- tuna on toasted rye w/ sharp cheese. I can't tell you how good it tastes... I'm in the kitchen even before I shower. I'm wondering what other folks crave after a bike workout.
