Backbone Trail Ultra - January 16, 2027
The Backbone Trail Ultra is a long-distance trail running event across the Backbone Trail in the Santa Monica Mountains, California. The solo course covers 68 miles and accumulates nearly 13,600 feet of elevation gain. The route begins at Will Rogers State Park and concludes with a descent on the Ray Miller Trail. The course follows ridge-line sections that include views of the Pacific Ocean.
Entry is limited to 200 participants. Solo entrants must have previously completed at least one 50-mile trail run as proof of experience. Relay teams of two, three, or four runners are permitted and do not have the solo entry prerequisite.
Organizers are working with National Parks, State Parks, MRCA, and other local agencies to secure permits for the event date. Registration opens on October 1, 2026 at 12:00 AM PT.
A prior edition of the event was canceled in 2019 due to damage from the Woolsey Wildfire. Other details about aid stations, exact relay legs, and logistical arrangements are not specified here. Visit the organization's website for the most recent information.
