Our marathon course offers international appeal, traversing both downtown Detroit and Windsor, Ontario, crossing the border at both the Ambassador Bridge and Detroit-Windsor Tunnel. You will run through historic neighborhoods, around beautiful Belle Isle, and along the spectacular RiverWalk.
The new start-finish line splits the difference between the locales. It is at Fort and Cass, two blocks east of the Free Press' former offices and two blocks west of its new offices. On one side of the street is the old Detroit Club, a four-story brick and stone building; on the other is the Fort Washington Plaza, a 16-story glass and concrete building. The new line will be used for the start and finish of the marathon, the international half marathon and the five-person marathon relay, plus the finish of the U.S. only half-marathon. The change to the start-finish line leads to a series of other relatively minor course changes. The course follows its traditional western path on Fort to the Ambassador Bridge. The distance to the bridge is two-tenths of a mile farther than past years. In fact, all the points on the course are two-tenths farther than last year (except the finish line, of course). The marathon course makes its final turn north from Larned to Fort on Griswold Street instead of Washington Boulevard. The marathon and half-marathon courses still separate at Griswold and Fort. The finish-line chute has been shortened from two blocks to one. After finishing, runners will walk for a block and then turn north on First Street, where the postrace amenities await.
Due to its use of the tunnel, the race is able to boast that it has the only official underwater international mile in the world, as the tunnel runs underneath the Detroit River.
