Marlboro, Vermont to Greenfield, Massachusetts

Registration for the 2026 marathon will open at noon on January 1, 2026

The New England Green River Marathon is one of the most beautiful races in New England. Starting in Marlboro, Vermont and following the course of the Green River through an 1870’s covered bridge, and ending with a finish-line celebration in the shade of maple trees at Greenfield Community College in Massachusetts. This USATF-certified (Certification MA18003JK) course has a net 1,400 foot drop over a rolling, downhill course that has seen many personal best and Boston qualifying times for well-trained runners. Our course does not fall under BAA’s downhill results indexing because its net downhill is less than 1500 feet, so there is no adjustment of times for the purposes of Boston qualification.

FindMyMarathon.com ranks our marathon as the 17th fastest course in the nation and the fastest in New England!
