Trail Running Event in Los Olivos
The Born to Run Ultra Marathons take place on a ranch in Los Olivos, California. The event features a course consisting of 100% dirt surfaces, including ranch roads and single-track trails. The layout utilizes two one-way 10-mile loops that meet at a central point, allowing participants to access their vehicles every 10 miles for self-crewing. Loop 1 includes approximately 2,100 feet of elevation gain and is marked with pink ribbons, while Loop 2 includes 1,600 feet of gain and is marked with yellow ribbons.
The event offers several endurance distances and timed challenges:
- 96-hour (4-day) run
- 72-hour (3-day) run
- 100-mile run
- 30-mile run
- 20-mile run
- 10-mile run
Participants in the multi-day and 100-mile events have access to onsite camping. Aid stations are positioned approximately every 5 miles along the course. For the 96-hour and 72-hour timed events, awards are presented to the top male and female runners based on the total number of laps completed. Specific mileage milestones, such as 100 miles or 200 miles within the allotted timeframes, are recognized with buckles.
Registration is limited to 300 participants and guests. All attendees, including pacers and crew, must obtain a ranch access pass. The ranch gate operates on a strict schedule, and professional security monitors the entrance after hours. No dogs are permitted on the course.
