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 (NCT) through the Allegheny National Forest (ANF) in 50 hours, beginning at 6 p.m. on Friday and ending at 8 p.m. on Sunday. This year it will run from south to north; the direction changes from year to year to give hikers a chance to see the whole trail.

In 2019, 140 hikers started the challenge. Finishers included 18 at 25 miles, 72 at 50 miles, four at 75 miles, and 17 at 100 miles. Each year more than half the participants sign up to attempt the 100 miles. Of those, usually only about 20% are able to reach their goal. Most who fall short of the 100 miles complete their hike at the 50-mile mark for various reasons including injury, time, and energy. The ANF Chapter encourages participants to consider carefully their chosen mileage goals, as no transportation is guaranteed except the shuttle from your chosen end point to the starting line.

Any hiker who is less than 18 years old by June 12 must hike with an adult (18 or older) during the A-100 Challenge. Minor registrants must provide that adult’s name at the time of registration. Additionally, the event waiver must be signed by the parent or guardian.

Please review the Allegheny 100 Hiking Challenge Frequently Asked Questions sheet. Additional questions can be directed to or via the ANF Chapter Facebook page

Please note the lottery deadlines and know there is no wait list. Walk-ins the day of the event will be accepted, but you are entirely responsible for your own transportation. Walk-ins may or may not receive a shirt depending on size availability; we order a few extra of every size each year, but depending on the number of walk-ins, these may run out. Each shuttle bus has a list of participants that are to be on that bus, and space is extremely limited. No one who has not preregistered will be allowed on the shuttle bus.
