TSR Trail Race - Adams, MA

The TSR Trail Race is a loop-format trail event taking place in Adams, Massachusetts on June 21, 2026. Runners may choose to complete one, two, or three laps of the course; the exact length of a single loop is still being determined.

The course uses singletrack and hiking trails located north of the Greylock Glen, combining machine-built and hand-built sections. Terrain blends ups and downs with smoother flats, offering flowy trail running across mixed surfaces.

This event is organized by the Thunderbolt Ski Runners. All proceeds support the stewardship work the Thunderbolt Ski Runners provide for mountain bike and ski trails around the Greylock Glen and Mount Greylock.

Registration for the event is handled online, with a registration deadline on June 19, 2026. The venue address is Gould Road, Adams, MA 01220.
