I'm bad, I normally don't eat breakfast. When I eat a bunch before a ride start I feel really sluggish, and even get a little low-blood sugar reaction about an hour into the ride. So what I've been doing for many years is to have just a single apple and a banana about 20 minutes before the ride start. Mainly that's because I have apples at home, and I can pick up a banana at the 7-11 That seems a good compromise between over-and-undereating for me.
