North on W Shadow Lake Drive to Prairie Flower Rd go in tunnel under Birch St past Rice Lake Elementary into the Rice Creek Chain of Lakes Park Reserve. Go past the Chomonix Golf Course and east to Centerville. Go east on Main St to the bike path running parallel to 20th Ave south till it heads west until it spills out on Sherman Lake Rd. Just before Meganser Ct take a left back on the trail until it enters Pondview Circle. Catch Sherman Lake Rd briefly until you make Timberwolf Trail which you take south until you get to Birch. Go west (right turn) and ride either the trail or the wide shoulder of Birch St to Black Duck Drive. Take Black Duck Drive north until it ends and take the bike path around the north side of Reshanau Lake until you connect again with W Shadow Lake Drive which you can ride back to the start. NOTE: Rather than crossing Birch where the roundabout construction is going on, best to return under the tunnel to Prairie Flower Rd.
