Dirty Dash 10k & Half Marathon

Dirty Dash is the newest race in the Dirty Trail Series, taking you to a brand-new venue at the Shelterhouse Picnic Area in South Chagrin Reservation of the Cleveland Metroparks. Choose between a 10k (hikers welcome!) or a half marathon. The course winds through lush forests, rolling terrain, and around the Sulphur Springs Loop, where you are treated to the babbling sounds of Sulphur Springs and views of small waterfalls. Both distances feature wooded single-track, creek-side paths, and just enough elevation change to keep things interesting. The setting feels tucked away and quiet, offering a true trail-running experience.

Whether you’re chasing a personal record or simply taking in the scenery, the course delivers a balanced mix of challenge and enjoyment. With its natural beauty and varied terrain, the Dirty Dash is a great option for trail veterans and first-timers alike. If you’re looking for a race that blends scenery, effort, and dirt underfoot, this one belongs on your calendar.
