Runner's diarrhea is a condition that often affects distance runners characterized by an urgent need for a bowel movement mid-run. Whether the stool can be considered diarrhea, or a clinical expression of ischemic enteropathy, is under debate.

Causes
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. Diet is often cited as a common cause of diarrhea in distance runners, particularly with meals including berries and dried fruit.

Treatment and prevention
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.
Famous cases
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 passed diarrhea. She later blamed a meal of grilled salmon from the previous night for the incident.
