Eat a good amount of time before riding. I used to shower first in the morning to get a jump on the day and I would pretty much each last of all. That's reversed now. I'll often eat first thing or at least before I take the dog for her walk. That way I have time to get things settled, digesting, and a little stored up energy for my ride.
I find that exercise makes me un-hungry, so if I've skipped a meal and then ride, when I come down from the ride I'll be so unbelievably hungry that you might actually find me in the crawlspace trying to gnaw my way up to the next floor where the cafeteria is.
Good advice. I forgot about hydration.

How much time between the last bite and pedaling? How hard do you go? I really need an hour before riding if I'm going to go hard.
