Fueling your body

Just as a car needs fuel to run, so do our bodies.

Eating right for race day

Just as a car needs fuel to run, so do our bodies. If you’ve ever felt like you’re “running on empty,” it could mean you have not fueled your body with the proper nutrition. By including the right amount of carbohydrates, proteins and fats into your diet, as well as essential vitamins and minerals, you can make the most out of your fitness routine and training by allowing your body to produce energy most efficiently for peak performance and endurance.

Basic fueling guidelines

Before exercise

  • Drink 14 to 20 ounces of water or a sports drink two to three hours before your run to ensure you’re hydrated.
  • Drink 8 ounces just prior to your workout or run, especially if it’s hot or humid.
  • Check the color of your urine — it should be light yellow. If it is dark, you need to drink more.
  • Two to four hours before your run, have a snack or light meal (200 to 300 g carbohydrates):
    • High carbohydrate, moderate protein, low fat, low fiber
    • Good snacks are a smoothie, peanut butter and honey toast, oatmeal with fruit and almonds, low-fat cottage cheese or crackers and fruit
  • One hour before your run, have a light snack, such as an energy bar or fruit (30 to 60 g carbohydrates). For an early morning workout, eat something smaller, such as half an energy bar or a sports drink.

During exercise

  • Hydrating: Drink regularly during exercise to replace fluids lost through sweat. Weigh yourself before and after a run to determine fluid loss, replacing 16 ounces of fluid for every pound lost.
  • Eating: If your workout will be shorter than 60 to 90 minutes, there is no need to take along a snack. When workouts or distance runs increase to 90 minutes or longer, eating 30 to 60 g carbohydrates every hour is recommended. Sports bars, gels or drinks, or fruit are ideal.

After exercising

  • Fifteen to 30 minutes after exercising, consume carbohydrates, protein and 16 ounces of fluid for every pound lost, for example, 8 to 16 ounces low-fat chocolate milk, a smoothie with yogurt and berries, or a sports drink and sports bar.
  • Repeat 2 hours after exercising.

Race day

  • Eat a carbohydrate-rich meal one to four hours before the race, such as toast, bagel or English muffin with jam or jelly, cereal, fruit, low-fat yogurt, sports bar, fruit juice and skim milk.
  • Avoid high-fiber and high-fat foods on race day, as they may cause abdominal cramping.
