About
The Dirty Dirty 15K challenges runners on the trails of North Chagrin Reservation, part of the Cleveland Metroparks system in Willoughby Hills, Ohio. The 15K route follows two scenic loops through varied terrain, including woods and open meadows, and passes landmarks such as Squire's Castle and Buttermilk Falls.
You can run or walk the course while taking in the surrounding nature and wildlife. Afterward, the event wraps up with a season-ending gathering that includes a meal, prizes, and an awards ceremony celebrating the full Dirty Trail series.
