Runners follow an out-and-back course for the Parkinson’s Half Marathon, which starts near Fireman’s Park in Cottage Grove and finishes at the trailhead for the Glacial Drumlin State Trail, which will also serve as the course for most of the race. The course heads east from Cottage Grove nearly all the way to the nearby town of Deerfield, where runners hit the turnaround point and head back along the trail to the race finish line.
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.
