Duathlon Races in Michigan

The duathlon race calendar in Michigan is busiest in September, June, and August, with races most often in Brighton, Detroit, Grand Rapids, and Shelby Township.

What a duathlon is

A duathlon is a triathlon without the swim: you run, transition to the bike, ride, then transition back and finish on foot. Two disciplines, two timed transitions, no open water — which makes it one of the most accessible ways into multisport racing.

Most US duathlons run one of two distances. A sprint is roughly a 5K run, 20K bike, and 2.5K run — short enough to finish on a first attempt. The standard, often called Olympic, doubles the front end to a 10K run, 40K bike, and 5K run. Exact distances vary by organizer.
