Black Toenail Friday Half Marathon

The Black Toenail Friday Half Marathon and 7.5 Miler is a popular trail running event held annually at Proud Lake State Recreation Area in Commerce Township, Michigan. Scheduled for Friday, November 28, 2025, this race offers both a half marathon and a 7.5-mile distance, with options for in-person or virtual participation. Starting late morning, it allows runners to enjoy Thanksgiving festivities and still get a good run on well-groomed trails surrounded by Michigan’s scenic late fall landscape.

Participants receive a custom long-sleeve tech shirt, finisher medal, post-race food, and awards. The event is part of the Trivium Michigan Mega Medal Series, making it a festive tradition to kick off the holiday season on the trails. Visit the organization's website for the most recent information.
