This is a loop course that starts and ends at Temescal Park (the intersection of Temescal Road and Sunset Blvd.) After walking the service road through Temescal Park, the run starts in a clockwise direction and traverses the Temescal Park Waterfall. From the Waterfall, the run continues up the Temescal West Ridge to the Temescal Ridge Fire Road and then to Will Rogers State Park via the spectacular Will Rogers Backbone Trial. The final leg continues up scenic Rivas Canyon and then back to Temescal Park.
