Vegan high carb low fat is the optimum training and racing fuel. Clean, easy digesting, lots of energy. Save the fats for when you go below race weight and need to get back up there.
I'd be interested in reading up on this, eg meal suggestions, snacks etc. Any recommendations?
I don't know who dvincere would suggest you read but, since he didn't chime back in, you should really check out the website of WeightWeenies contributor and raw vegan nutrition guru DurianRider. His website is http://www.30bananasaday.com/
Even if you don't decide to go that diet route, it is worth checking out his stuff, in particular his Youtube vids, both because he is an avid cyclist as well as just for the pure entertainment value. That balls on that guy are unbelievable!
P.S. I don't think that diet is necessarily optimal either, and am personally more in the direction of Kwalker nutritionally speaking. It does seem like there is some individual variation in results though, so give it a shot and see how you feel.
