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 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. Learn more at VisitAnnArbor.org ! E-RACE THE STIGMA We are continuing our charity takeover! In partnership with the Rotary Club of Ann Arbor we are committing all our fundraising efforts to organizations that help and support mental health and/or issues associated with mental health and play an active role in reducing the stigma surrounding mental illness. You will learn about them during registration, and we hope you will choose to support one or many to help E-Race the Stigma!
