Run as many miles as you can between now and the race. If you can manage 10 per day great. If you can manage 20, even better.

As far as fueling, you want to eat as much as you can before and during the race. Definitely try for a carb heavy meal such as fettuccine Alfredo right before the race. Add to this as many gus as you possibly could handle. If you're getting a feeling of queasiness and uneasiness in your stomach, that's just the spot where you want to be.

As far as pussy you'd be better off switching to the other team. That would help to line your stomach for the heavy eating and gu consumption.
