San Diego’s most beautiful 50 mile running event – this is an out-and-back course mostly on single track trail along the Pacific Crest Trail in east San Diego County. The trail features numerous climbs, particularly on the “out” portion, as well as some rocky sections. It begins at an elevation of approximately 3,000 feet, reaching 6,000 feet in the Laguna Mountains, with changing eco-cultures and beautiful vistas. (Note: routing is subject to final approval from the U.S. Forest Service.)
