The Endless Mountains 430 Challenge is a multi-surface masterpiece comprised of rural dirt and gravel roads, rail trails, paved roads through small historic downtowns, and various ascents over scenic rolling hills. This route, known as the Endless Mountains Gravel Bikepacking Loop (EMGBL), begins and ends in Towanda, Pennsylvania, along the beautiful Susquehanna River’s North Branch.

The EMGBL is intended to be an epic multi-day adventure route across the four counties of Bradford, Sullivan, Susquehanna, and Wyoming in the Endless Mountains in northeast PA. Now, the Endless Mountains 430 Challenge will transform that multi-day adventure into a challenging and picturesque endurance race.

This event is fully self-supported and riders assume all risks and responsibilities for navigation, safety, overnight stops, sourcing resupply along the way, and determining how to best complete the challenging course. Registration is free, but each participant will be required to sign up for a satellite tracker via to participate in the competition (rentals are available, or you can use your own Inreach or Spot; some costs apply).

Detailed course information will be sent to registered participants after June 1, and Trackleaders registration will open one month before the event. Be sure to register early to receive updates and additional information leading up to September 21. Each rider needs to register, and individual and team categories will be selected at Trackleaders registration.
