Start time

The race starts at 7 a.m. ET on Fort St. and 2nd Ave. in Downtown Detroit.

How to watch

There is no live television coverage for the race, but local news will have post-race coverage. The marathon’s Facebook page will have video, and a year ago the Live section broadcast briefly from the starting line.

Course map

The runners start at Fort St. and 2nd Ave. in Downtown Detroit. They finish along Woodward Ave. just south of Campus Martius Park. They cross into Canada on mile 4 by way of the Ambassador Bridge. They return to Detroit on mile 8 by going underwater through the Detroit-Windsor Tunnel. The course includes a run through the Woodbridge neighborhood, the District Detroit, Eastern Market, and the Dequindre Cut.
