Recommendations:
Before exercise or less than one hour, drink 300-500ml of water. Add 30-50g of carbohydrate if exercise is to last longer than an hour.
During exercise of less than one hour, drink 500-1000ml of water. During longer exercise, drink 800-1600ml of a sports drink per hour.
After exercise, rehydration needs can usually be met through food and water. If you’re competing again within a few hours, rehydrate
using a sports drink.
