Full disclosure, I used to map every long run around bathroom access — just in case.
I thought i just had a “sensitive tummy” or that “runners trots” were a normal part of running.
That’s what every article said. That’s what my doctor said.
But I never knew I gut symptoms were a stress response and an immune response.
→ Fasted running (body → panic mode)
→ Fueling too late (gut forced to digest while running at threshold)
→ Restricting carbs → gut bacteria starved, inflammation rising
→ Food allergies → causing further irritation and inflammation
The problem wasn’t my gut.
The problem was that nobody ever taught me how to fuel for digestive health to feel safe during the run.
Once I started making some small but significant dietary adjustments — timing, nutrient variety and eating for my needs, I went from emergency-runner to confident-runner. But this took time, some trial and error, but long term success that has me a lot more in tune with my body and what it needs.
I know it’s never fun to talk about, but with the recent studies on runners with poor digestive health, know that I’m here and this is a big part of what I work with my clients on. Digestion is never TMI in my books!
