How to Avoid And Solve Nutrition and Stomach Issues in Ultramarathons

August 19, 2026 · 1 h 8 min

Show notes

Nutrition can make or break an ultramarathon. In this episode, we’re breaking down one of the most frustrating parts of ultra running: what happens when your fueling strategy stops working. From nausea and stomach issues to palate fatigue, hydration mistakes, and struggling to stay consistent.

You’ll learn how to troubleshoot problems instead of guessing, practice fueling in training, and build the flexibility and discipline needed to keep yourself moving forward.

In this episode, you’ll learn:

-How to tell the difference between true nausea and simply being tired of your fuel

-Why hydration may be playing a bigger role in your GI issues than you realize

-How to build more variety into your race-day nutrition

-Why experimenting with one variable at a time matters

-What your fueling timing can do for your stomach

-How to troubleshoot carbs, sodium, magnesium, caffeine, and ingredient sensitivities

-Why your nutrition strategy needs to evolve with distance, intensity, heat, and race conditions

-How to develop the discipline to keep fueling when food is the last thing you want
