Major international airport with frequent service; downtown Detroit hotels are walkable to start/finish. Main complexity is the passport requirement for international distances and early corral corralling logistics.
Stay downtown (Campus Martius / Greektown area) for walkable access to expo, start corrals, and finish line. Rideshare (Uber/Lyft) is reliable in Detroit. Windsor, ON is a short drive or walk across the bridge/tunnel for post-race dining.
Best for / avoid if
Best for
- BQ chasers on a fast course
- runners who want a true international race experience
- destination racers pairing Detroit culture with competition
- relay teams looking for a unique group challenge
- PR-seekers
- Boston qualifiers
- runners wanting an international course
- runners enjoying urban culture
Avoid if
- you don't have a WHTI-compliant document (passport/passport card) for the international distances
- you want a non-road or trail experience
- you need guaranteed entry — it sells out within days of January 1 opening
- Discomfort with border crossings
- Preference for trails
- Urban race avoiders
First-timer mistakes
Starting too fast — the Ambassador Bridge hill hits at mile 3 and will punish an aggressive opening pace. Also, many first-timers forget their passport or passport card; without a WHTI document you cannot register for the marathon or international half.
