2025 Endless Mountains 430 & 250 Challenge

The Endless Mountains 430 & 250 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. The 250-mile option occupies the eastern loop of the EMGBL and also starts and ends in Towanda.
