GMAA Sap Run

The GMAA Sap Run is a certified 10 km road race held in Westford, Vermont. This event marks its 45th year and is conducted by the Green Mountain Athletic Association. The course is a certified out-and-back route (VT21003JK) that takes participants through the rural landscape of Westford.

The running surface consists of country roads that are typically muddy and hilly. Participants start on Brookside Road directly in front of Westford Elementary School. From there, the course heads south along Brookside Road and continues onto Pettingill Road. Runners reach a turnaround point at the 3-mile mark and return along the same path, concluding the race in the school driveway.

Registration options include:

The event offers discounted entry fees for GMAA members. Pre-registration is conducted online until the Friday before the race, while race-day registration is also available on-site at the Westford School. The organizers do not offer refunds, deferrals, or transfers for this event. Facilities at the Westford Elementary School serve as the primary location for pre-race and post-race activities.
