Why Endurance Athletes Struggle with GI Issues (And How to Actually Fix Them)

In episode 137 of The Eat for Endurance Podcast, I’m joined by Sports Dietitian Kylee Van Horn, RDN for a deep dive into one of the most common (and frustrating) challenges endurance athletes face… GI issues.
From nausea and vomiting to bloating, cramping, and diarrhea, GI symptoms can seriously impact training, racing, and confidence around fueling.
The tricky part? It’s usually not just one thing causing the problem.
Kylee and I discuss:
- Why GI issues are so common during endurance exercise
- The difference between upper vs. lower GI symptoms
- Why you may need to stop blaming the gels
- Common fueling and hydration mistakes that contribute to GI distress
- The role of underfueling and low energy availability
- Gut training and improving carb tolerance during exercise
- Fueling considerations for marathons, triathlons, and ultras
- When GI symptoms may warrant further medical evaluation
While GI challenges are common in endurance athletes, they are not something you just have to accept as “normal.” With the right strategy, support, and a bit of troubleshooting, most athletes can significantly improve their symptoms.
