Runners follow a point-to-point course for the Old Sandwich Road Race Half Marathon, which starts along the edge of Ellisville Harbor State Park, a coastal park that lies just to the south of Plymouth and overlooks the scenic Cape Cod Bay. From there, runners follow the twists and turns of Old Sandwich Road as it winds its way northwest toward the turn at Clifford Road, along tree-lined and wooded trails through most of the route.
Note: The course map above provides the approximate route for the race.
