I think it would be pretty similar to what everyone eats: some sort of complex carb, good protein and fat meal in the morning, make sure to get your carbs in after you ride and have a good meal within an hour or so of racing. I used to like quinoa, fruit and almonds plus half a bagel with peanut butter. I think you could probably follow any recommended diet, just sub in your proteins of choice.
I really recommend an omega 3 supplement that isn't just flax or walnuts. They have capsules that are extracted from pursulane.
