Trinity Health Probility Ann Arbor Marathon

The Ann Arbor Marathon is a multi-distance fall weekend centered on downtown Ann Arbor and the University of Michigan. The full marathon pairs a city race atmosphere with river and park sections.

The certified road course moves through campus, beside the Huron River, and through Gallup Park and Nichols Arboretum. Rolling terrain and late climbs make even pacing more important than the urban setting might suggest.

Early October in Ann Arbor usually starts cool and can turn mild by late morning. Rain and autumn wind are possible, so layers that can be shed are useful.
