Pre-race nutrition is going to be pretty personal.
In general, you aren't going to want eat anything out of your norm. I'd also stay away from anything overly rich or heavy.
My current game plan is to eat a nice large breakfast and a pretty decent lunch. I'll probably have some form of sandwich around 5:00pm and then a Clif Bar or something similar around 9....I personally don't like eating a meal less than 3 hours before a race or game starts.
15 minutes before the race, I'll pop a Gatorade G01 and then chew up a Clif Block every 20-30 mins during the run itself.
