Runners in all four races will follow the North Shore trails along Clinton Lake inside Clinton State Park for this trail race just outside Lawrence, along a course filled with tree roots, stream crossings, rocky trails and rolling hills. Wildlife are often spotted along the trails during the race — everything from squirrels and snakes to deer and ducks — and the weather in the days leading up to the race can play a big role in how muddy or how dry the trails are on race day.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
