Fueling Before Running a Half Marathon

During the week before you run a half marathon, you need to focus on both hydration and providing sufficient energy/fueling.  Your calorie intake will be higher than usual and you will increase your carb load. It is also important that you hydrate in the week leading up to race day. You can supplement your water intake with nuun hydration to make sure you are getting the electrolytes your body needs to be sufficiently hydrated come race morning.

When you combine carbohydrate loading and tapering your workouts, you can store more energy in your muscles which will give you more energy sources during your event.

The Mayo Clinic suggests that carb-loading begins one week before the event with another additional increase 1-3 days out. ” Increase your carbohydrate intake to about 8 to 12 grams of carbohydrate per kilogram of body weight. Cut back on foods higher in fat to compensate for the extra carbohydrate-rich foods. Also, scale back your training for three to four days before the event. The combination of eating more carbohydrates and tapering activity appears to boost muscle glycogen stores.

For most athletes, 5 to 7 grams of carbohydrate per kilogram of body weight daily is right for general training. (Note that 1 kilogram equals 2.2 pounds.) Endurance athletes may need up to 12 grams per kilogram.”10 Low carb hit SvV | Voedingscentrum | Flickr

To give you an idea of carb counts, these foods have 15 grams of carbohydrates:

  • One slice of bread
  • One 6-inch tortilla
  • 1/2 cup mashed potatoes
  • 1/2 medium baked potato or sweet potato
  • 1/3 cup rice
  • One small apple
  • Two tangerines
  • 2 tablespoons raisins
  • 1/2 cup orange juice
  • 3 cups green beans
  • 1 1/4 cup milk or yogurt

On race morning you will want to rise early so that you can eat at least 2-3 hours before your start time. This will allow you to digest and not have a heavy stomach. Oversleep? Don’t panic, go with a lighter meal with supplemented liquid or gel carbs.

Planning what to eat during a race can be overwhelming. With so many variables, it’s hard to determine what the “right” answer is for you. When deciding what to eat and drink, we think it’s helpful to break it down by looking at the nutrients your body needs.

A successful nutrition plan takes into account the number of calories your system can handle in an hour. It should also factor in your body’s need for electrolytes, amino acids, water, and protein. When thinking about your nutritional need for a race or training session, it’s important to remember that everyone is different. Every day is different. For example, body size, air temperature, activity type, intensity, and personal preference will affect your nutritional needs.

That’s why we recommend mixing and matching products to find out what works for you. For example, if you prefer to drink your calories, you can bottle up your fuel using ROCTANE Energy Drink.
