North Country Trail Association

Allegheny 100 Challenge

The A-100 is an unsupported endurance hiking challenge with no timekeepers, no aid stations, and no finish line other than the one hikers set for themselves.

The event challenges hikers to traverse 25, 50, 75 or 100 miles along the North Country Trail through the Allegheny National Forest (ANF) in 50 hours, always beginning at 6:00 p.m. on a Friday and ending at 8:00 p.m. the following Sunday. Each year, the starting direction changes (south to north then north to south) to give hikers a chance to see the whole section of Trail.

Each year more than half the participants sign up to attempt the 100 miles, though usually only about 20% are able to reach their goal. But most who fall short of the 100 miles still complete 50 miles. The ANF Chapter encourages participants to consider time, energy and the possibility of injury. Participants are also encouraged to carefully choose mileage goals, as no transportation is guaranteed except the shuttle from your chosen end point back to the starting line. In 2019, 140 hikers started the challenge, 111 finished:

25 miles: 18
50 miles: 72
75 miles: 4
100 miles: 17
