Does the conventional wisdom on pre-race hydration need a complete overhaul, or are we just drinking to a myth thats been perpetuated by the sports drink industry? Is it possible that the emphasis on hyper-hydration in the hours leading up to a competition is actually doing more harm than good, particularly for athletes who are adapted to training in a state of mild dehydration? Should we be focusing on individualized hydration strategies that take into account factors like sweat rate, environmental conditions, and genetic variability, rather than relying on blanket recommendations that may not be applicable to everyone?
