Endurance & Energy

Built for longer sessions and endurance sport — carbohydrate and energy powders, isotonic drinks, electrolyte tablets, caffeine products, gels and single-serve shots.

For anything over about an hour, the two things that usually matter are carbohydrate intake and fluid replacement. Carbohydrate powders let you set the grams per hour yourself and are the cheapest route; isotonic drink mixes combine carbs and salts in fixed ratios and are simpler to use on the move. Electrolyte tablets and powders add sodium and other salts without much fuel, which suits hot conditions and lower-intensity work. Energy drinks and shots are the grab-and-go option, and energy gels are the compact way to carry fuel on a run or a ride. Whatever you pick, test it in training rather than on race day.
