Course and race information

The course is a loop of approximately 10.5 to 11 miles per loop. The 17k uses one loop and the 50k uses three loops. The route is rolling and consists of about 50% technical single track on the Metacomet Trail, with the remainder on double-track and forest roads. Sections can be extremely rocky and include a notable power line hill; the course will not change.
