The New England Green River Marathon is one of the most scenic races in New England. Running along the mostly wooded banks of the Green River, from Marlboro College in Vermont to Greenfield Community College in Massachusetts, the rolling, downhill course features a net 1,450-foot drop. If you like small, rural, community races through some of the most beautiful landscape in New England, then this is the marathon for you. This race raises funds for the Connecticut River Conservancy’s efforts to preserve and clean-up the Green River, one of the many tributaries that flow into the Connecticut River, and also supports the Sugarloaf Mountain Athletic Club’s activities in the Pioneer Valley.
