Are you the type of runner that knows exactly where every public toilet is along your route?

Don’t worry - you are not alone! 30-50% of athletes regularly suffer from gastrointestinal (GI) problems while exercising.

Far too common among endurance athletes, GI symptoms include nausea, cramps, bloating, wind, vomiting, diarrhoea and urgency. It seems that the frequency, intensity and severity of these symptoms increases as the event distance increases.

So why exactly does it happen? And what can you do to prevent runners gut?

In this episode I share my top tips to help you. Tune in to find out!

If you’re sick of choosing running routes based on toilet availability, come and join me inside the Triathlon Nutrition Academy! Doors open on the 19th of September 2021
