Macro partitioning

Female endurance athletes should consume 8-10 g of carbohydrates per kg of body weight in the 3 days leading up to an event (carbohydrate loading) to maximize muscle glycogen stores, with particular emphasis on this strategy during the luteal phase of the menstrual cycle.

Three days before your big race or long event, increase your carbohydrate intake to 8-10 grams for every kilogram of your body weight. This means eating more pasta, rice, and fruits than usual. This strategy fills your muscle glycogen stores, giving you more energy for the event. This is especially important if you are in the luteal phase (second half) of your menstrual cycle, as your body may burn through glycogen faster.
