The Dirty Herd is a collection of individuals who love trail running. Whether you're a trail running novice or a skilled single track navigator, join us and discover the epic adventure waiting for you in the woods each week. The Dirty Herd Classics are fun runs, there are no timing mechanisms involved and are an opportunity to put on a fun, free event for the trail running community. Bring a signed waiver to the event.
