Backbone Trail Ultra
The Backbone Trail Ultra is an ultra-distance trail race that follows the full Backbone Trail through the Santa Monica Mountains in California. The primary distance is 68 miles, beginning at Will Rogers State Park and running along ridge lines toward the coast. The course accumulates nearly 13,600 feet of elevation gain and finishes with a descent on the Ray Miller Trail that provides Pacific Ocean views.
Participation is capped at 200 runners. Solo entrants must show proof of having completed at least one previous 50-mile trail run. Relay teams of two, three, or four are allowed and do not require the 50-mile prerequisite.
The Backbone Trail project has been pursued for more than 50 years to create a fully linked route for hikers and runners. Sections of the trail were damaged by the Woolsey Wildfire, and that damage led to the cancellation of the 2019 event. The organizer lists registration opening on January 1, 2027.
The race emphasizes long-distance singletrack and ridge-top terrain with repeated climbs and coastal scenery. Field size limits and the solo qualification requirement are key logistical details for participants. Visit the organization's website for the most recent information.
