Marathon
The road to complete recovery after a marathon is difficult but not impossible. Do not stop running soon after the marathon, take an ice bath and get into some compression wear before you prepare for a long and sound sleep soon after the marathon. Replenish your body with antioxidant-rich food and enroll in an aerobics class till you recover completely.
Eat a banana before and after a run. It's full of carbs, antioxidants, vitamin B6, and potassium. Before and as you run, munch on a whole grain, nutty energy bar or just pop in a handful of potassium- and iron-rich raisins. Mix 2 tbsps cereals with 1/2 cup yogurt and 1 tsp honey before a run. Or eat a whole baked beetroot. Drink enough water, about 5–12 ounces every 15 mins during the run. But don't overhydrate yourself.
