Fueling your Body for Peak Performance Now that you are training for your marathon or half marathon, you know how important it is to be healthy so that your training can go smoothly. Giving your body the right fuel will build your energy reserves for stressful workouts and allow you to have high quality training sessions. Choosing nutritious foods with optimal amounts of vitamins and minerals will also help in minimizing injury. On a daily basis you should make sure to get the right balance of carbohydrate and protein. Your higher exercise levels demands more fuel in the form of carbohydrates.
Protein is required to build and maintain muscle.
Fluid intake should be consistently high to match your losses through sweat. Improper hydration results in poor performance. Additional fluid should be consumed when the weather is hot and humid. You should drink amounts that produce light-coloured urine. It is very important to have some readily available fuel in your system before your run.
