A late-season race worth traveling for.

Triathlete Magazine named The Dirty Mitten one of the Best Off-the-Beaten-Path Multisport Races in the U.S. for 2026. On September 20, the gravel triathlon closes the 2026 Michigan Triathlon Series presented by Rockefeller Global Family Office.

It is a finish-line weekend with real character, from the lake to the gravel to the trails at YMCA Camp Manitou-Lin.
