A-100 Challenge: 25, 50, 75, or 100 miles in 50 hours


The A-100 takes place over all or some of the nearly 100 miles of North Country Trail that lie within the Allegheny National Forest. You can do your planned miles alone (most common) or with a buddy or two. I’m posting this so Phoenix members can have the info to sign up. I can answer questions from my past participation but will not participate this year.

Registration opens for the 2023 A-100 this Friday, March 10th at 12 pm here:

This year’s event will take place from Friday, June 9th - Sunday, June 11th, and will run South to North. Details on this year’s registration are as follows:
Registration will close at 12 pm, Friday, March 17th, or when we hit our cap of participants. Please note there will be no waitlist.

The cost of this year’s event will be $80, it does not include membership to the NCTA. Payment will be due upon registration.

After payment is complete you will be directed to a site to collect your personal information. This step is crucial. You will not be able to participate in the event if we do not have this information.

We have new swag this year - an A-100 tech hat! Registration includes the use of the shuttle from your chosen end point to the start.

Walk-in registrants will be accepted on the day of the event but will be entirely responsible for their own transportation, they will not be able to use the shuttle service. Walk-ins are not guaranteed event swag.

An email with more information will be sent out to registrants closer to the event date. In the meantime, please check the link above for our FAQ. Questions? Reply or email us at

See you on the trail!
