Runner's diarrhea, often termed as a condition that often affects distance runners, is 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.
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.
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.
At Rio 2016 Olympic Games, walk race world record holder Yohann Diniz defecated during the 50km competition, when he was near the 15 km mark. He also passed out, near the 30 km mark. Nevertheless, he finished the race at the 8th position.
