We are Michigan's largest road race! From 26.2 to 1 mile, we have a race for everyone. Our course offers international appeal by crossing into Canada over the Ambassador Bridge and back through the Detroit-Windsor Tunnel. You'll also explore Detroit's historic neighborhoods before finishing in Downtown Detroit. Whether you're ready to conquer a full marathon or a 5K, make sure you run with us. Join us for Detroit's Marathon Weekend, Oct. 17-18, 2020!
