The Big Sur Trail Marathon, Half Marathon & 5 Mile is a scenic and challenging trail running event held annually at Andrew Molera State Park. As one of California's smaller running events, it has a strict limit of 300 participants, which contributes to its intimate atmosphere and ensures it sells out quickly each year. Runners can choose from three distinct distances—a full marathon, half marathon, or a 5-mile race—all of which take place on the historic Old Coast Road. The course is known for its steep climbs and descents, rewarding runners with breathtaking views of the Pacific coastline, redwood forests, and oak groves.
