About this race
THE PROBILITY ANN ARBOR MARATHON
Take to the scenic streets of Ann Arbor to help E-Race the Stigma with the 16th running of the Trinity Health Probility Ann Arbor Marathon. With a variety of running events that appeal to all ages and abilities, you’ll find that the Ann Arbor Marathon is your ideal fall race event, whether you’re walking your first 5K or running your 50th marathon.
RUN TREE TOWN.
All distance events — marathon, marathon relay, half marathon, 10K, and 5K — start in downtown Ann Arbor at 209 S Ashley St, Ann Arbor, MI 48104. Run through the vibrant streets of downtown Ann Arbor, then wind your way through the panoramic University of Michigan campus. The marathon, half-marathon, and 10K courses also encompass stretches along the Huron River and Gallup Park and through Nichols Arboretum before returning to campus and downtown. All races end with a spectacular downtown finish. The Ann Arbor Marathon course is USATF certified and serves as a qualifier for both the Boston and New York Marathons.
If you’re coming in from out of town, out of state, or out of the country — or even if you live in the Ann Arbor Area — you’ll enjoy discovering Tree Town USA! Ann Arbor features locally owned and operated restaurants and cafes, independent bookstores, theaters, art galleries, and museums (including the University of Michigan Museum of Art), all within reach of the Ann Arbor Marathon.

Early Start Option: Marathon (26.2)
Plan on taking more than 6 hours to finish? Choose our early start option when you register! Please note that packet pickup opens at 6 a.m. which is the same time as the early start option. This means that you will need to pick up your packet at the expo the day before the race. We will record your start time as 6 a.m. You will need to have a headlamp and any hydration that you will need before 8:00 a.m when the course officially opens. Remember that the course will be marked, but there will not be any police or volunteers on the course until 7:30 a.m. so you will need to follow traffic laws and it will be good to be familiar with the course. The course will close promptly at 2 p.m. At that time, if you are still on the course, you will need to move to the sidewalks. You, of course, may finish the race, but the finish area will begin cleaning up.
