About the race
The Big Burro 24HR is a timed trail race held April 30 – May 1, 2027, in the Maple Hills Trail System in Big Bear City, California. Runners have 24 hours to complete as many laps as possible on an approximately 5 mile loop that returns to a central Start/Finish basecamp. The course uses existing singletrack and features a mix of runnable sections, punchy climbs, rocky stretches, fast descents, and typical Big Bear mountain terrain. Aid is provided at the Start/Finish Basecamp and at two on-course stations: Shore Drive Aid Station and Elementary Trailhead Aid Station.
Crew access is allowed from the Start/Finish area only. The event includes an overall competition for the greatest number of full laps completed within 24 hours and awards for the top overall male and female finishers. The Burro Hundred challenge requires completion of twenty full laps (100 miles) within the 24 hour limit; finishers receive an official belt buckle, recognition on the finisher list, and lifetime membership in the Burro Hundred Club. Organizers run a pre-race volunteer trail work day, remove course markings after the event, and donate five dollars from each entry to the Bear Valley Education Foundation for trail maintenance. The inaugural running will establish course records for overall laps and for the fastest 100 mile time. Visit the organization's website for the most recent information.
