Runner's diarrhea, also known as runner's colitis,[1] the Indian shimmy[2] or runner's trots[3] is a condition that often affects distance runners characterized by an urgent need for a bowel movement mid-run.

Causes

[edit]

The causes of runner's diarrhea remain under debate, although several theories include ischemia and mechanical trauma. The reduced incidence of diarrhea in cyclists would indicate the latter.[4] Diet is often cited as a common cause of diarrhea in distance runners.[5]

Treatment

[edit]

Runner's diarrhea will normally clear up by itself from several hours to two days after running. As with all forms of diarrhea, replacement of fluids and electrolytes is advisable. Methods to prevent runner's diarrhea will vary between individuals, although it is advisable to consider examining the pre-running diet to determine potential trigger foods.[6]

Notable cases

[edit]
  • At the 2005 London Marathon, winner Paula Radcliffe, in desperate need for a toilet break during the race, stopped by the road in full view of the crowd and live TV cameras and defecated. She later blamed a surfeit of pasta and grilled salmon from the previous night for the incident.[8]
  • At the 2008 Göteborgsvarvet half marathon, Mikael Ekvall finished the race in 21st place in spite of being stained with his own excrement. A reporter asked him if he had ever considered stopping to clean off. He explained: "No, I'd lose time. […] If you quit once, it's easy to do it again and again and again. It becomes a habit."[9]
  • At the 2019 Perm International Marathon, Alexander Novikov [ru] finished first despite suffering from a bout of diarrhea, which left his clothes sodden.[11]
