Saddleback Marathon

The Saddleback Marathon, held in Silverado, California, is a premier trail running event set in the scenic Saddleback Mountains within the Cleveland National Forest. Offering marathon, half marathon, and 10K distances, the race features challenging courses with significant elevation gains—4,244 feet for the marathon, 1,773 feet for the half, and 706 feet for the 10K. The marathon route begins on Black Star Canyon Road, traversing creekside trails, switchbacks, and the Mariposa Reserve before descending Skyline Drive into Corona.

Known for its rugged terrain and natural beauty, the event includes multiple aid stations and enforces a cutoff time due to course difficulty. The race has a history of rerouting due to wildfires but remains a celebrated annual trail running challenge. Visit the organization's website for the most recent information.
