Running at different paces will not only add variety to your training, it’s also the most effective way to enhance your overall performance. Short, fast bursts will improve your racing sharpness and your body’s capacity to pump blood and oxygen
to run low on glycogen during the race. To avoid this, try to drink five or six mouthfuls of a carbohydrate drink 15 minutes before the start of the marathon and every 15 minutes during the run. This is something you should practise regularlythroughout
