Marlboro, Vermont to Greenfield, Massachusetts

Alert: Registration for deferred runners is now open! Please visit the registration page for details. Deferred runners from the 2020 race have until February 28 to re-register for the 2021 race. After that their registration code will expire.

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 classic covered bridge, and ending with a finish-line celebration in the shade of maple trees at Greenfield Community College in Massachusetts. Hosted by the Sugarloaf Mountain Athletic Club in partnership with Connecticut River Conservancy, the race builds community in support of the environment and to help our runners achieve their goals. This USATF-certified (Certification MA18003JK), Boston qualifier course has a net 1,400 foot drop over a rolling, downhill course that has seen many personal best and qualifying times for well-trained runners.

2021 UPDATE: Registration for deferred runners is now open! If you registered for the 2020 race and were deferred to 2021, please check your email for instructions on registration. Don’t see it? Check your spam folder. Still don’t see it? Let us know and we’ll get you sorted out. You will have until February 28 to register at no additional cost using your unique deferral code. On March 1, we will open up any remaining spaces to general registration. We can’t wait for this year’s race on Sunday, August 29, 2021! Thank you for your patience as we navigate our way through this strange new world!
