If you are looking for extreme competition, then you might consider Big Dog’s Backyard Ultra. Big Dog’s Backyard Ultra could be the toughest and weirdest race you’ve ever heard of, which only ends once only one person is standing.

The competition is joined by people from all walks of life, and a Belgian dentist holds the current record at 75 hours or 312 miles of running.
