A long-standing favourite among the endurance crowd, HIGH5’s 2:1 delivers the energy you need in the form of glucose and fructose in a 2:1 ratio, which optimises the carbohydrate delivery to your muscles. It also contains sodium and potassium – key electrolytes lost through sweat – and comes in an easy-access tub.
