Runner's Gut: Causes and Proven Tips to Prevent Intestinal Distress During Runs

Ever felt an urgent bathroom break mid-run? It's a common, if embarrassing, issue for runners. The repetitive motion of running stimulates your digestive system, often leading to discomfort.

The Cause

The main trigger is the jarring impact of running, which pressures your stomach and intestines, causing cramps or sudden urges. Blood flow to the gut also drops during exercise, hindering digestion and exacerbating symptoms.
