Nutrition is often referred to as the "fourth discipline" of triathlon because it's crucial to train your body to absorb nutrients during a race. Personally, I use Maurten and NutriD during my competitions, but training intensively with these products can get quite expensive. That's why I'm sharing my recipe for a homemade sports drink. With this recipe, you can easily prepare your own drink containing 60 to 120 grams of carbohydrates per hour—at just a fraction of the cost.
