This run is one of the oldest ultra-trail events in the world and certainly one of the most challenging. It follows the Western States Trail from Squaw Valley to Auburn traveling remote and rugged territory, much of which is accessible only to hikers, horses and helicopters. In the miles between Squaw Valley and Auburn, runners experience the majestic high country beauty of Emigrant Pass and the Granite Chief Wilderness, the crucible of the canyons of the California gold country, a memorable crossing of the ice-cold waters of the main stem of the Middle Fork of the American River, and, during the latter stages, the historic reddish-brown-colored trails that led gold-seeking prospectors and homesteading pilgrims alike to the welcoming arms of Auburn. Specific information is available in the Western States Endurance Run web site.
