Snowbird DirtyBird Mud Run

July 11, 2015. Be a part of history. The inaugural DirtyBird Mud Run hosts the "Longest Slip 'n' Slide" in the world, 5.5 miles of downhill terrain, 15+ never seen before obstacles, 3,000' of descent (plus a little climbing to keep you honest), a million laughs and a world-class après party at the finish line!
