Runners start the Groundhog Half Marathon course, like the full marathon, in the Meadows of Millennium Park. From there, runners head onto the Kent Trail for the first mile, and turn right onto the newer, paved Fred Meijer Millennium Trail that parallels Butterworth Street. You’ll follow this all the way west and south. After that, the course heads all the way back to the start, where you’ll repeat the loop you’ve just run two more times for the half marathon, and five more times for the full marathon.
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.
