Where to watch

Read the geography first

The course returns toward its starting district. Use the map to choose a fixed anchor and the finish, and never build a plan that requires crossing the live route.

Landmarks that make useful anchors

Moving around race morning

Assume your car is parked and stays parked. The Detroit-Windsor Tunnel closes on race Sunday, and the race's own pages give two different windows for it: the current FAQ says the closure "will last from approximately 6:15-10:30 a.m.," while the race's own getting-downtown guide says the tunnel is "closed to vehicle traffic from 6:15 a.m. and will reopen to traffic at 10:00a.m." That tunnel is your mile 7.71-8.89 Underwater Mile, +60 feet, which is exactly why it is shut. The Ambassador Bridge runs on a similar clock, described on the race site as "closed to vehicle traffic from 6 a.m. until the last runner clears the bridge, which will be approximately 9:15 a.m.", while the current FAQ softens that to "restricted traffic." Around all of it, closures on named streets ripple outward: eastbound Fort Street closes at Grand Boulevard, southbound Woodward at Charlotte/Edmund, the Lodge southbound after the Howard Street exit, Lafayette westbound at Iroquois, and northbound streets off Jefferson are limited because of the Larned Street course lines. News coverage of the most recent edition says course roads start closing as early as 4 a.m. Neither the race nor the city published a tow-away enforcement time on any page I fetched, so treat any on-street space near the course as a space you should not use at all rather than gambling on a posted hour.
