Dirty Dirty 15k

Prepare for a double dirty trail challenge at the Dirty Dirty 15k, the final race of the Dirty Trail Series. This course takes you on an exciting two-loop tour through the picturesque North Chagrin Reservation of the Cleveland Metroparks. The park's delicate balance between outdoor recreation and wildlife preservation is the perfect backdrop for your race. It will test your endurance while also allowing you to connect with nature as you run or hike alongside wildlife sanctuaries.

On this reverse run of the Dirty Love 15k, you will be greeted by diverse and scenic landscapes, from woodlands to meadows, and along the way, you'll encounter iconic landmarks such as Squires Castle, Buttermilk Falls, and Oxbow Lagoon.

Don't miss this last chance to embrace the thrill of a Dirty Trail Series race this year and have some fun with us afterward. Join us for the year-end Dirty Series Party, with food, prizes, and the much anticipated Dirty Series awards ceremony!
