The Dirty Mitten Trail Run

The Dirty Mitten Trail Run is a 5K race held in Middleville, Michigan, at YMCA Camp Manitou-Lin on Saturday, September 20, 2025. Billed as 'the dirtiest event in the Mitten,' the course blends single-track forest trails with fields and gravel roads through the camp. Debuting as part of Dirtfest Weekend, the event pairs with the Dirty Mitten Gravel Bike Race and the Dirty Mitten Gravel Triathlon.

Participants who complete all three events join a select group and earn bragging rights plus swag as the Greenleaf Trust Trifecta. The race location and weekend atmosphere emphasize community, challenge, and outdoor trail-running camaraderie. Visit the organization's website for the most recent information.
