The Badwater Salton Sea, an 81-mile ultra-running challenge, beckons teams of two or three to traverse the formidable landscapes of Southern California on April 18, 2026, starting from Borrego Springs, CA. This renowned event, part of the prestigious Badwater Ultra Cup, plunges runners from 234 feet below sea level at the "post-apocalyptic" shores of the Salton Sea, ascending over 9,000 feet to the 5,500-foot summit of Palomar Mountain. The course is a demanding blend of road and an eight-mile single-track trail section through the Anza-Borrego State Park, surprising many with its steepness, rugged terrain, and intense heat. Typical race day conditions can see highs around 87°F and lows of 57°F, with a minimal 1% chance of precipitation, though veterans warn of extreme weather shifts, from scorching desert heat and potential sandstorms to freezing temperatures and fog or even hail at higher elevations.

What truly sets Badwater Salton Sea apart is its unique "Team Ultra Racing" format; duos or trios must run together for the entire duration, not as a relay, fostering an unparalleled sense of teamwork and shared endurance. Unlike conventional races, there are no traditional aid stations; instead, each team is required to have a dedicated support vehicle and at least two crew members to provide all necessary provisions and assistance throughout the arduous journey. Runners often highlight the camaraderie and collective energy of the Badwater races, making this "extremely difficult" event as challenging as any of the toughest 100-milers. The race headquarters and a key time station are located at the Borrego Springs Resort around mile 35, offering a temporary oasis before the final push towards the Palomar Mountain finish line, where the famous Observatory becomes a distant, then approaching, beacon.
