As you can see there are many variations on a theme!
I used to be afraid to eat before a ride because I would ride so hard I'd get close to barfing.
On a bike tour, though, I discovered I could eat anything anytime. Even huge meals. It just means taking it easier on the ride after eating. A huge meal and hammering out 20 miles is a recipe for blowing chunks.
Now I find a happy medium works. LIGHT breakfast, ride fast, eat snacks at work, big lunch, ride faster home.
