Badwater Salton Sea

Badwater Salton Sea, presented by Mount to Coast, is an 81-mile team ultramarathon in Southern California, from Salton City (about 234 feet below sea level) to Palomar Mountain (about 5,500 feet). The course blends road and single-track trail—eight miles pass through Anza-Borrego State Park—with a total elevation gain over 9,000 feet. Runners compete as two- or three-person teams, staying together for the full distance and sharing one support vehicle.

Held in Borrego Springs on April 18–19, 2026, the event is renowned for extreme heat by day and frigid, foggy nights; finishers earn buckles and official ranking only when the team remains intact. Visit the organization's website for the most recent information.
