In 2019 the Leaf Peepers Half Marathon/5K races will return to River Rd. in Duxbury.  Both races start and finish at the horseshoe entrance to the Waterbury state office complex. The Half Marathon course is out and back along River Rd. finishing along the trail behind the state offices, and the 5K will be a loop course also finishing along the trail.

Course maps will be posted here when they are available.
