Michigan Triathlon / Duathlon Championship 2026

The Michigan Triathlon / Duathlon Championship begins early on Labor Day weekend at Belle Isle State Park in Detroit, situated on an island in the Detroit River between Detroit and Windsor, Canada. This event features a multisport race day including Olympic, Sprint, and Super Sprint triathlons, alongside aquabike, duathlon, duathlon relay, and triathlon relay options. The Olympic triathlon consists of a 1500-meter swim, a 24.9-mile bike ride, and a 6.2-mile run. The Sprint offers half the swim and bike distance with a 3.1-mile run, while the Super Sprint is shorter with a 200-yard swim, a 6-mile bike, and a 2-mile run. Aquabike participants complete the swim and bike segments only, and duathletes undertake a 3.1-mile run, a 10-mile bike ride, followed by another 3.1-mile run. The swim takes place in the Detroit River, benefiting from the current, contributing to the course's reputation as one of the fastest in the United States. The bike course is flat, utilizing a closed lane for a straightforward and rapid cycling segment, distinct from a technical route. The run course also follows a coned closed lane, passing historical sites on Belle Isle. TriFind notes this race is identical to the Motor City Triathlon, allowing athletes to compete on a very similar course and compare their seasonal times.
