Ten unique towns dot the 150-mile nature trail that stretches from Cumberland, Md. to Pittsburgh, and up to 800 runners will experience them all on the Great Allegheny Passage Relay this October.

Regular teams of eight and ultra teams of four will run the flat, vehicle-free trail over 48 hours. Teammates will take turns tackling the race's 24 legs, only stopping for brief breaks in the team's van that follows along the course. That means a single participant may run anywhere from 13 to 46 miles -- depending on team size -- over the duration of the race.
