How fast is it?
Slower than most Ohio trail 10Ks
The fastest quarter of the 2026 10K field finished under 1:11:02, against 1:06:23 in a typical Ohio trail 10K, so times here run 7 percent slower.
- Half Marathon: Slower than most Ohio trail half marathons. The fastest quarter of the 2026 half marathon field finished under 2:35:41, against 2:23:21 in a typical Ohio trail half marathon, so times here run 9 percent slower.
Compares the fastest quarter of each field, so walkers and first-timers do not skew it. It reflects the course and the field together: a flat course, cool weather, or a competitive crowd all make times faster.

From the organizers
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.
