Butterfield Backyard Ultra

The Butterfield Backyard Ultra, hosted by Happy Trails Racing, takes place at Butterfield Trailhead Regional Park in Herriman, Utah, nestled near the Oquirrh Mountains. This unique event features a 4.167-mile loop course on mostly trail terrain with 512 feet of elevation gain, which runners complete once every hour for either 6 or 12 hours. Participants must finish each loop within the hour to continue, with the final "Legacy Loop" timed to determine overall winners.

The race emphasizes camaraderie, mental and physical endurance, and a festive atmosphere with ample space for friends and family to gather. Awards include finisher medals and custom leather patch beanies for those completing 50 miles. Visit the organization's website for the most recent information.
