Episode 43: The Science of Sweat | How to Actually Fuel and Hydrate for Endurance with Tash Cooper-Smith

Sports scientist and triathlete Tash Cooper-Smith from Precision Fuel & Hydration joins The Infirmary to demystify one of endurance sport's most confusing topics: fueling and hydration. Tash breaks down sweat testing, sodium concentration, carbohydrate intake, gut training, and the actual science behind cramping — and why the answer to most athletes' fueling problems is rarely as complicated as they make it. She also shares the story of her own athletic journey, from competitive gymnastics to Kona qualifier in four years, and what that experience taught her about personalizing nutrition for performance.
