One of the original long distance fuels, Sustained Energy has attained a legendary status in the world of endurance sports since its introduction in 1992. Tested and proven in virtually every endurance event on the planet, Sustained Energy’s unique 7:1 carbohydrate to protein ratio, and it’s neutral flavor, is still the first choice of thousands of athletes. After about two hours of exercise you need to have some protein in your fuel or you will start to cannibalize or break down precious muscle tissue. So when your exercise goes beyond the range of Hammer Gel or HEED alone, Sustained Energy is ready to serve you, providing premium fuel complemented with specific nutrients that support enhanced fat utilization and lactic acid buffering.

Give Sustained Energy a try – you’ll have 100% confidence in your fuel – and you’ll understand why it’s been the choice of thousands of endurance athletes for well over a decade. For maximum fueling variety and flexibility during your longest and hardest training sessions and races, mix or alternate Sustained Energy with Hammer Gel, HEED and/or Perpetuem.
