Stunning 68-mile ridge line romp across the full length of the Santa Monica Mountains Backbone Trail, brought to you by the giddy-with-excitement Coyote Cohorts and their extended community of equally giddy volunteers. We are adding a 100 miler this year. The 68 miles can be run as a Fun Run or a Competitive Run. Choose your option but understand that once you have committed, you can't change.
