Dirty Dirty 15k 2026

The Dirty Dirty 15K is a two-loop trail race at North Chagrin Reservation in Willoughby Hills, Ohio, serving as the final event of the Dirty Trail Series. It utilizes Cleveland Metroparks bridle trails, and hikers are permitted, meaning the field includes participants not solely focused on racing from the start. The race features a gun start with chip timing, finisher medals, aid stations, post-race refreshments, and limited restroom facilities. The course proceeds counter-clockwise through North Chagrin, retracing the Dirty Love 15K route. It passes Squires Castle, Buttermilk Falls, and Oxbow Lagoon, crossing woodlands, meadows, and wildlife sanctuary areas. The trails are described as runnable and well-marked, featuring rolling hills with a single significant climb and descent. Following the race, the series concludes with food, prizes, and Dirty Series awards. Donations associated with the event benefit the Trails Division of Cleveland Metroparks.
