Big Burro 24 Hour
The Big Burro 24 Hour is a timed trail race on the Maple Hills Trail System in Big Bear City, CA, held April 30 – May 1, 2027. Runners complete as many laps as possible during a 24-hour period on an approximately 5-mile loop that returns to a central Start/Finish basecamp each lap. The overall winner is the runner who completes the most full laps within the time limit.
The course follows existing trails and features runnable singletrack, punchy climbs, rocky sections, and fast descents typical of Big Bear mountain terrain. Each lap brings runners back to the basecamp area, which hosts primary aid, timing, crew access, medical support, and race operations.
On-course aid stations include Shore Drive Aid Station and Elementary Trailhead Aid Station. Runners may crew from the Start/Finish area only.
The event includes a 100-mile challenge called the Burro Hundred: complete twenty full laps within 24 hours to earn an official belt buckle, recognition on the Burro Hundred Finisher List, and lifetime membership in the Burro Hundred Club. Awards are presented to the top overall male and female finishers.
Organizers coordinate a volunteer trail work day before the race, remove course markings after the event, and donate five dollars from every race entry to the Bear Valley Education Foundation for trail maintenance. Visit the organization's website for the most recent information.
