The idea for the New England Green River Marathon was sparked by the exceptional beauty of the course itself, which follows nearly the entire length of the Green River from its headwaters in Marlboro, Vermont to its confluence with the Deerfield River in Greenfield, Massachusetts. It’s a favorite running spot for many local runners; we can’t think of a better place to run, and we’d like to share it with you! This is a small, rural, community race and isn’t a big money maker; to us it’s more about getting together to celebrate our love of the outdoors and running.
