Here’s your pre-race plan
The food you eat on the day of the race should be high in carbohydrates and low (not zero) in fats and proteins. Fats and proteins do provide energy, but they’re harder to digest and your body takes longer to extract the energy from them.
4-5 hours before race: 1.0 – 1.5 gm of carbs per pound of body weight
2 hours before race: 0.5 – 1.0 gm of carbs per pound of body weight
half hour before race: 0.5 gm of carb per pound of body weight
4-5 hours before race: 2-3 cups
2 hours before race: 2 cups
half hour before race: 2 cups
During the race
Research on nutrition during a race has shown a potential benefit from taking in about 0.4 grams of carbohydrate per hour per pound of body weight. For someone 150 pounds, that means 60-70 grams per hour.
Examples of foods containing 70 grams of carbohydrate include
- 3/4 cup of raisins
- 3 bananas
But many runners choose gels, power bars, or sports drinks instead. The product label will tell you how many carbs these contain.
Different authorities suggest different amounts of fluid intake. Ultimately, you’ll have to figure out what’s best for you. The amount you want to drink will also depend on temperature and humidity.
For a baseline starting point, plan to consume about 1.5 ml of water per pound of body weight every 20 minutes. For a 150 pound person, that translates into 225 milliliters, or 7-8 ounces every 20 minutes.
