I prefer spelt flour English muffins with honey and peanut butter. Coffee. Lots of water. This is the same routine I have for morning training rides. Then during my warmup, I'll reach for Clif shot bloks or a Clif drink, and this is what I have during races.

A lot of my races have been EARLY. I can't get quite enough time to have a meal and then recover. Then I have to focus more on the Clif stuff during a warmup, so that I won't have real food in my stomach too close to the event. If it's a crit, there's usually no problem, because I don't need gobs and gobs of calories anyway.

Still, for an early race especially but for racing in general, it's very important to have something you're used to for dinner the night before. This can be hard, because when you're traveling, often what's available is junk or restaurant fare that is just too rich. All of that plus race day stress can do a number on your belly regardless of what you do for breakfast. You want a good dinner, plenty of water, and enough time to digest and feel good going to bed. It really helps your race day routine go smoothly.
