Sage advice:
Train your tummy. Trying new foods on race day is a recipe for disaster. So spend these last few weeks test-driving anything you plan to eat or drink -- from your prerun meal and midrun fuel to lots of hydrating along the way. As you do, keep these guidelines in mind:

• For breakfast, go heavy on carbs (the energy source you'll tap into when things get tough) about 90 minutes before the start. Popular picks include oatmeal, a bagel with peanut butter or a waffle and honey.

• During the race, you'll need another 30-60 grams of carbohydrates somewhere after the first hour (the amount in a packaged gel or two of those small, paper cups of sports drink they'll be handing out along the course). Remember, adding calories on the move can be a shock to your stomach, so be sure to experiment with this, too.

• Last, but certainly not least, practice hydrating. Feel free to pass on water stations for the first 60 minutes, but start drinking after that, alternating water and sports drinks. Also, use your remaining runs learning to gulp, not sip. Big swigs gets liquid through the stomach faster, keeping you more hydrated, less bloated, and better primed for your soon-to-be photo finish.
