Ann Arbor Marathon, Half Marathon, 10K & 5K

Sunday, October 1, 2023 • Ann Arbor, MI • Course Map

Set for its 12th annual running here at the home of the University of Michigan, the Probility Ann Arbor Marathon, Half Marathon, 10K & 5K runs along a loop course that starts and finishes on the university campus and features views of the city’s downtown as well as stretches along the winding Huron River.

If you’re a college football fan, the starting line is likely to be quite familiar to you — it’s near the University of Michigan Wolverines football stadium on Main Street, also known as the “Big House.”

The race begins along 5th Avenue, just north of the stadium. From there, the course for the full and half marathon share the same route

Shortly after the first mile, those running the half marathon turn right to head south on State Street, where they’ll run an out-and-back stretch south and then north again on State before turning right again onto University Avenue.

Those running the full skip the State Street turn and instead head east on University, and then join Geddes Avenue for a stretch that takes them past the Forest Hill Cemetery and Nichols Arboretum.

Runners in the half marathon head back along University through downtown Ann Arbor, where they’ll run a long, out-and-back stretch (with some hills), which turns more residential the further away you get from downtown.

The next stretch of the race brings runners into the second half of the half marathon, along South University Avenue and then south on State Street. Runners cross the finish line on Main Street, between Liberty and William Streets.
