ExoLactate Gel Aims to Redefine Tour de France Fueling

Aitor Viribay’s ExoLactate, a lactate-based energy gel, is pitched as a breakthrough in endurance fueling, arguing lactate can serve as a primary energy source to support fat burning at low effort and rapid carbohydrate energy at high intensity, potentially giving cyclists a competitive edge in the Tour de France. After past attempts with exogenous lactate reportedly failed, ExoLactate has reportedly cleared regulatory hurdles and is being tested with elite athletes, raising hope that lactate fueling could redefine cycling nutrition—though its practical adoption and verification remain a topic of debate.
