Experience the unparalleled beauty of nature at the New England Green River Marathon. The race begins in the quaint town of Marlboro, Vermont, where you'll start your journey along the picturesque banks of the historic Green River. As you run through this idyllic landscape, you’ll pass by an 1870s covered bridge, a testament to America's rich architectural heritage. The course is known for its rolling terrain and gradual downhill sections, offering runners breathtaking views as they descend towards the finish line. The net elevation drop of 1,400 feet ensures a dynamic and exhilarating experience that has inspired many athletes to achieve personal bests and even qualify for Boston through this challenging yet rewarding route. After your run, cross the finish line beneath the shade of maple trees on the grounds of Greenfield Community College in Massachusetts. Here, you'll be greeted by a celebratory atmosphere filled with post-race refreshments and camaraderie among fellow runners. For those who wish to make their participation even more meaningful, there is an opportunity to join the Stream Team. By pledging an additional $250, participants can support the Connecticut River Conservancy (CRC) in its vital work restoring clean water, promoting healthy habitats, and building resilient communities that sustain a diverse and thriving watershed. This USATF-certified race not only offers a stunning natural setting but also provides runners with a chance to contribute positively to environmental conservation efforts. Whether you're aiming for personal excellence or simply looking to enjoy the scenic trails of New England, this marathon promises an unforgettable experience.
