BTW, just to elaborate on the effects of eating too close to the ride, for folks who might not be familiar with it: when you eat, the food is broken down and becomes glucose in the bloodstream. The cells of your body can't admit glucose molecules without the presence of insulin, so your body reacts to the presence of blood glucose by creating extra insulin. This works great unless you start using up a bunch of glucose by exercising. Now you've got more insulin in your system than is required and your blood sugar levels rapidly drop, resulting in fatigue, light headedness, sweating, and the other fun symptoms of the bonk.
So the idea is to either eat long before you start exercising, so the blood insulin levels stabilize, or after you've begun exercising, so your body knows not to release too much insulin in the first place.
HTH!
