Scott & Don

This episode is focused on the fuel that drives endurance athletes. It’s a world where what you eat isn’t just about satisfying hunger; it’s about strategy, precision, and sometimes, survival.

Joining us from Australia are two experts of sports dietetics, Steph Gaskell and Alan Mccubbin, co-hosts of “The Fueling Endurance” podcast. Steph, a trail runner herself, is an expert of exercise-induced gastrointestinal syndrome. She’s on a mission to unravel the mysteries of how our guts betray us during a run and how to keep the digestive peace. Then there’s Alan, a man who can talk about sodium and hydration. With a background in mountain biking and sailing, he knows the fine line between staying hydrated and hitting a wall.


  • Dehydration can increase the risk of gut symptoms and impact digestion, absorption, and the integrity of the gastrointestinal tract.
  • Vomiting may provide temporary relief from gastrointestinal stress, but it does not eliminate the underlying issue.
  • Cramping can be caused by a combination of factors, including hydration, electrolyte balance, neuromuscular responses, muscle fatigue, and psychological stress.
  • Sweat rate and electrolyte loss are not always correlated, and individual variations exist in sweat sodium concentration.
