When a person runs faster or longer than they're accustomed to, they might have sharp, sudden urges to defecate. The defecation is usually diarrheal, and the runner feels greatly relieved afterwards.

Man #1 - I can't believe we've ran for 10 miles!
Man #2 - Neither can I. But can we stop soon? I think I might be catching Runner's Bowel Syndrome.
