Big Burro 24HR

Big Burro 24 Hour 24 Hours. 5-Mile Loop. Sunset to Sunset.The Big Burro 24 Hour is an old-school mountain ultra on the Maple Hills Trail System in Big Bear, California.Runners will complete as many laps as possible on an approximately 5-mile loop over 24 hours. The format is simple: start at sunset, run through the night, see what you have left when the sun comes back up, and keep moving until sunset Saturday.This is not a polished road race. It is a gritty, community-driven trail event built around good people, hard miles, a lively basecamp, and the kind of suffering that makes ultras worth doing.Event DetailsDate: April 30 – May 1, 2027Location: Maple Hills Trail System, Big Bear, CAStart Time: Sunset Friday, approximately 7:00 PMFinish Time: Sunset Saturday, approximately 7:00 PMFormat: Timed trail raceCourse: Approx. 5-mile loopWinner: Most completed laps in 24 hoursCourseThe course uses existing trails within the Maple Hills Trail System.Expect a mix of runnable singletrack, punchy
