Proteins should account for 15-20% of the diet with sources such as chicken, turkey, fish, and legumes while fats should make up the remaining 15-20% from foods like avocados, nuts, seeds, and oils.

This period sees an increase in carbohydrate intake to about 70-75% of total calories, accompanied by a decrease in training intensity or volume. Foods like pasta, rice, bread, and potatoes are particularly beneficial during this phase.

The meal, ideally rich in carbohydrates, should also include 15-20 grams of protein to promote satiety and prevent muscle damage. A sample may include a bowl of oatmeal with some berries and a tablespoon of almond butter.

Post-Race Nutrition: Promote Recovery and Replenish Glycogen Stores

Post-race, it’s essential to refuel the body with a balanced mix of carbohydrates and protein, hydrate with electrolytes, and incorporate omega-3 rich food items for their anti-inflammatory benefits.
