Before Running

Your pre-exercise goal is to be fueled for your training. The ideal pre-exercise meal should be carbohydrate rich and well tolerated. The number of carbohydrates you need depends on your weight and the timing of the meal prior to exercise. Generally, you should consume 0.5g to 2g per pound of body weight of carbohydrate 1 to 4 hours prior to exercise.

An hour before a run, consume 0.5 grams of carbohydrate per pound of body weight. For a 145-lb runner that’s 145 lb x 0.5 g/lb or 72.5 grams of carbohydrates.

Sample meal:
1. one small banana (15g of carbs) + one slice toast (15g of carbs) + one Tbsp of jam (15g of carbs) + 16oz of Gatorade (30g of carbs) = 75 grams of carbohydrate
2. one cup of cooked oatmeal (30g of carbs) + 4 Tbsp raisins (30g of carbs) + 8 oz Gatorade (15g of carbs) = 75 grams of carbohydrate

During Running

Consuming 30 to 60 grams of carbohydrates every hour has proven to improve performance in exercise lasting longer than 90 minutes. Your pre-workout meal will provide enough energy for exercises lasting less than 90 minutes. Try gels, energy drinks, or anything that you can tolerate.

After Running

If your exercise lasts longer than 90 minutes, you should consume 0.7 grams of carbohydrate per pound of body weight immediately after exercise, followed by 0.7 grams of carbohydrates per pound of body weight 2 hours later, which will enhance your muscle recovery rate.

Consume carbohydrates that are quickly absorbed into your bloodstream. You may prefer a high carbohydrate drink if your stomach does not tolerate solid food immediately after exercise. Adding a small amount of protein (about 6-15grams) will also provide amino acids for building and repairing muscle tissue.

For a 145-lb runner that’s 145 lb x 0.7 g/lb or 101 grams of carbohydrates plus 6-15 grams of protein.

Sample meal:
one bagel (60 grams of carbs) + 8 oz chocolate milk (45 grams of carbs) + 2 oz of low fat cheese (14 grams of protein)
