Debunking Nutrition Norms in the Endurance Community with Alex Larson, MS, RDN, LD
Nutrition is one of the most overlooked drivers of performance in endurance sports and today we’re breaking down what happens when runners consistently under-fuel, why being exhausted after workouts isn’t a badge of honor, and how to fuel in a way that actually supports performance, recovery, and longevity in 2026.
In this episode, Coach Lauren sits down with registered dietitian, endurance athlete & coach Alex Larson to discuss why so many runners normalize all-day fatigue, GI distress, and stalled progress and how consistent, intentional fueling can change everything.
Lastly, they break down practical pre-run fueling strategies, how to improve gut tolerance, and why fasted runs and saving calories for later in the day often backfire.
In this episode we cover:
Why constant exhaustion after long or hard runs is often a fueling issue
The impact of chronic under-fueling
How fasted runs are often normalized and do more harm than good
Simple, realistic pre-run fueling ideas (including applesauce pouches and Pop-Tarts)
How to gradually build gut tolerance for pre-run and in-run nutrition
The potential link between poor fueling habits and GI distress
Why fueling matters at every level - not just for “fast” athletes
And if you’re realizing your training may be solid but your fueling isn't, this episode is just your starting point!
