Big Burro 24 Hour
The Big Burro 24 Hour is a 24-hour timed trail race held April 30 to May 1, 2027, in the Maple Hills Trail System near Big Bear City, California. Runners complete as many laps as possible on an approximately five mile loop during the 24 hour period.
The course uses existing trails and includes runnable singletrack, punchy climbs, rocky sections, and fast descents. Each lap returns participants to a Start/Finish basecamp that serves as the primary aid and race operations area.
Aid is available at the Start/Finish basecamp, the Shore Drive aid station, and the Elementary Trailhead aid station. Crew access is permitted from the Start/Finish area only. The event format awards the runner who completes the greatest number of full laps within 24 hours as the overall winner. Awards are given to the top overall male and female finishers.
The Burro Hundred is a specific challenge of 20 full laps, equal to 100 miles, completed within the 24 hour limit. Burro Hundred finishers receive an official belt buckle, recognition on the finisher list, and lifetime membership in the Burro Hundred Club.
Organizers coordinate a volunteer trail work day before race weekend, 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.
