Runners start the out-and-back course for the half marathon at the park’s Dyersville Bridge on Bull Creek Flats Road. From there, the race route heads south along the Avenue of the Giants (Highway 254), all the way along six and a half miles of paved roads to the turnaround point near Hammond Grove at Truss Creek, where runners then make the turn and retrace their steps back toward the start, where the race finish line lies.

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.
