If you've ever wondered how ultra running nutrition changes when races stretch beyond a single day, this episode reframes race day nutrition to better address multi-day endurance races.

Jesse Rich, nutritionist to elite ultrarunners, explains why traditional fueling advice breaks down during multi-day endurance efforts. As sleep deprivation, calorie deficits, and digestive fatigue accumulate, runners must think beyond electrolytes and gels and begin considering deeper nourishment ideas like how the body burns calories during mult-day events, how long it takes to absorb them again, and how sleep, recovery, and caffeine timing all affect performance.

For ultrarunners preparing for multi-day races like The Speed Project or anyone curious about how the body fuels extreme endurance.
