Both the half and the full marathons follow an out-and-back course that starts and finishes at Waukesha’s Schuetze Recreation Center on Baxter Street. From there, runners follow the trail that winds along the river starting in Frame Park, a linear park that lines both sides of the Fox River, which features nearly two miles of walking and biking trails. The half marathon turnaround occurs just after runners pass the mile 7 marker.
