The Detroit Free Press Marathon - the fastest growing marathon in the U.S. - has been held annually in October on the streets of downtown Detroit and Windsor, Ontario, since 1978. The event features a ½ marathon, 5k and youth mini-marathon, five-person relay and the full marathon including wheelchair and hand-cycle categories, and the running world’s only underwater international mile via the Detroit-Windsor Tunnel that crosses under the Detroit River. And I'm going to be there... Living United!
