Hypotonic sports drink
The best known example of a hypotonic sports drink is water. A hypotonic drink contains less dissolved substances than the concentration of substances in your blood. This means they are easily absorbed and good for hydration. A hypotonic sports drink contains a maximum of 4 grams of carbohydrates per 100 ml.
Hypotonic sports drinks are often the safest and wisest choice of drink to use while running. Jumbo Foodcoach advises you to use hypotonic sports drinks when training for less than an hour. If your carbohydrate stores are well replenished before you start running, you will not need the carbohydrates from the isotonic sports drink during exercise to sustain your effort.
Because training for less than an hour involves a relatively short burst of effort and drinking while running is difficult, you can choose to drink before you run instead.
