Course
The Detroit Marathon course
The only US marathon with an international component: the course crosses the Ambassador Bridge into Windsor, Ontario, runs several miles in Canada, and returns through the Detroit-Windsor tunnel, the only official underwater international mile in the sport. Bring a passport, and know that the tunnel mile is warm, loud, and has no GPS signal at all.

Away from the crossings the course is flat.

- 5K, Half marathon, Marathon
- Weather on race day
- Mid-October in Detroit is cold at the 7am start, often in the 30s or 40s, warming into the 50s. The bridge is exposed and windy in a way the rest of the course is not.
What to train for
Even-effort running without pace feedback.
Losing GPS in the tunnel around mile 8 throws people who race by watch, so practise running goal pace by feel and know your target splits from the mile markers.
Otherwise it is a conventional flat-marathon build.

Taper
Tapering for the Detroit Marathon
Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course is flat, so pacing decides the day: rehearse your goal pace in short segments during race week.

Detroit Marathon training questions
How long should I train for the Detroit Marathon?
Most runners give a marathon sixteen to twenty weeks of focused training on top of an existing base. The plan above counts back from your actual race date, so if you have less time than that it builds the best plan the remaining weeks allow rather than pretending you have longer.
Is the Detroit Marathon course hilly?
Flat. The only US marathon with an international component: the course crosses the Ambassador Bridge into Windsor, Ontario, runs several miles in Canada, and returns through the Detroit-Windsor tunnel, the only official underwater international mile in the sport.
What is the weather usually like at the Detroit Marathon?
Mid-October in Detroit is cold at the 7am start, often in the 30s or 40s, warming into the 50s. The bridge is exposed and windy in a way the rest of the course is not.
When should I start tapering for the Detroit Marathon?
Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. The course is flat, so pacing decides the day: rehearse your goal pace in short segments during race week.
