About
Held in Willowdale State Forest since 2001, the race follows a 12.5-mile loop of rocky, root-covered singletrack and doubletrack with about 1,100 feet of climbing per lap. Longer distances repeat the loop up to five times for the 100K. The 50-mile distance serves as the 2026 RRCA Massachusetts state championship, and proceeds support four local conservation groups.
