Groton Town Forest Trail Races

Groton, United States • 5 Oct 2025

Groton Town Forest Trail Races, held at 163 West Main Street, Groton, MA, offer two trail distances: 9.5 miles and 3.4 miles. The courses are well-marked and feature a scenic loop through Groton Town Forest with no road crossings, combining narrow dirt roads and single-track trails over roots, rocks, leaves, and rolling hills—challenging but not extreme. The event emphasizes trail-running atmosphere with aid stations (two on the longer course, one on the shorter) and light post-race refreshments.

Registration is capped at 250 runners. Prizes go to first-place male and female finishers in each race, with age-group prizes as well. Some proceeds support the Groton Trails Committee. Visit the organization's website for the most recent information.
