Borrego Springs, California (United States of America) - "Badwater Salton Sea". AdventureCorps hosts Badwater® Salton Sea annually in April. This remarkable event challenges up to 45 teams of two or three ultrarunners - running together as duos or trios for the duration, NOT in a relay - to tackle an unimaginable traverse of Southern California deserts and mountains. The route covers 81 miles (130km) from Salton City (elevation 234 feet / 71m below sea level) to Palomar Mountain, the almost tallest mountain in San Diego County (elevation 5500 feet / 1676m.) Eight of the 81 race miles pass through Anza-Borrego State Park on a single track trail known as the California Riding and Hiking Trail from near Borrego Springs to near Ranchita, creating a race route which is a mix of road and trail. There is a total elevation gain of over 9000 feet (2740m). www.badwater.com/event/badwater-salton-sea
