Backbone Trail Ultra, Santa Monica Mountains, CA
The Backbone Trail Ultra is a 68-mile point-to-point trail race across the Backbone Trail in the Santa Monica Mountains, California, scheduled for September 18, 2027. The course begins at Will Rogers State Park, follows the Backbone Trail along the coastal ridgeline, and finishes with a descent on the Ray Miller Trail.
The route accumulates nearly 13,600 feet of elevation gain and includes sections with Pacific Ocean views. The event accepts solo runners and relay teams of 2, 3, or 4 members. Participation is capped at 200 runners. Solo entrants must have completed at least one previous 50-mile trail race as proof of prior experience; relay teams do not require that prerequisite.
Registration opens January 1, 2027. The race is organized as an in-person outdoor event in the Santa Monica Mountains, CA. Past editions have been affected by wildfire damage, and organizers have worked with public agencies on permitting and course access.
