As to on-bike fueling, does it matter whether you choose feast or famine? Actually, neither is good. You needn’t stuff yourself with protein bars — or anything else, for that matter — but it’s unwise to go for long rides without eating.

This is about striking a balance between eating enough to keep your energy up; but not so much that you start to feel queasy. If you’re doing a long, organized ride, don’t spend too much time at rest stops; and don’t stuff yourself while you’re there! When you start riding again, your stomach is apt to feel like you’ve been eating bricks.

Experiment with this during training rides. As I discovered while preparing for my first century, what tastes good early in a ride might not be appealing later on; and prolonged hard effort makes me lose my appetite. But I’ve still got to eat — or bonk!
