Two hundred miles gives you more time to fix your problems, and a lot more time to create them. Most of those problems start with what you’re eating and drinking, or what you aren’t.
This week Kevin and Peter sit down with Claire Shorenstein, MS, RD, CSSD, a board-certified sports dietitian, longtime trail runner, and founder of Eat for Endurance. They cover how fueling changes once you’re past day one, why the science on 200s is mostly extrapolation from shorter races, and what that 2023 Cocodona 250 energy-deficit study found. Claire also grades Kevin’s non-negotiable pre-sleep rule for his athletes, walks through vomiting and GI troubleshooting, and explains why “not hungry” doesn’t mean “don’t need food.” Then Kevin offers up a totally hypothetical 37-year-old who eats like a toddler with a credit card.
Plus: Javelina Jundred commentary recap, Peter’s Halloween costume, a TrainingPeaks tip on TSS, a round of Let’s Get Deep, and Kevin’s new data-driven training plans for 2027.
