Join the 17th annual Vermont 50 MT Bike or Ultra Run to ride or run 50 miles of beautiful, but challenging, Vermont back roads and trails. Held in late September, the Vermont 50 has become a favorite race for ultra-runners and mt. bikers alike.  The mt. bikers love the technical single-track and challenging climbs. The runners love the back trails and open vistas.  And everybody loves the great fall foliage, camaraderie among runners and mt. bikers, abundant aid stations, and the great party at the finish line.
