## Resource

Ultra running nutrition is getting more extreme. More carbs, more precision, more pressure to “get it right.” But if you’ve ever had your stomach shut down mid-race, you know something isn’t adding up. This episode is for runners trying to fuel better without breaking their body in the process. I sit down with Chris Bellamy, engineer, ultra runner, and founder of Yanaa , to explore the hidden cost of the high-carb movement, what it’s doing to gut health, and why real food might be the missing piece. We get into the tension between performance and health, and what elite athletes are actually doing when it matters. This is for ultra runners who want to perform without sabotaging their system.
