Runner's Trots
Runner's trots are urgent loose stools during or after runs—driven by gut blood shift, jostling, fueling, and nerves, and managed with timing and gut training.
Runner's trots are sudden, urgent bowel movements during or right after running—loose stools, cramping, and the need to find a bathroom fast. Blood flow shifts away from the gut, jostling and hormones speed motility, and pre-run food or nerves add fuel.
It is common in distance runners, not a moral failing.
Common questions
-
Are runner's trots the same as food poisoning?
Trots often strike predictably with effort, heat, or pre-run meals—not random vomiting across rest days. Fever, blood, or symptoms off the trail need medical review.
