Trinity Health Probility Ann Arbor Marathon

The Trinity Health Probility Ann Arbor Marathon is a multi-event running festival held in downtown Ann Arbor on October 2 and 3, 2027. The event program includes road races, relay teams, walk-only options, kids races, and virtual entries. The marathon course is USATF certified and serves as a qualifier for the Boston Marathon and the TCS New York City Marathon.

Routes start and finish in downtown Ann Arbor and pass the University of Michigan campus and local natural areas such as the Huron River, Gallup Park, and Nichols Arboretum. The event includes an expo with packet pickup the day before the main races; there is no race day packet pickup for the marathon. An early start marathon option is available; early starters must carry a headlamp and personal hydration until aid stations are available and follow traffic laws while course support is limited. Several kids races offer free entry when paired with an adult's paid race confirmation number. Virtual race options allow participants to run the same distances at a time and place of their choosing.
