2. Eat Right: A huge part of running is meal planning—and not just what you eat, but when you eat. For example, I cannot eat within two hours of a race or I will get nauseous. However, my friend needs to scarf a protein bar 10 minutes before the start. Everybody is different, so use the six weeks to nail down what works best for you. The night before the race, carbo-load. This is the time when you get to choose pasta over protein. The day of the race, fuel up with a bagel or bread (for the carbs, which provide energy) and a banana (for the potassium, which prevents cramping).
