Western States 100-Mile Endurance Run

The Western States® 100-Mile Endurance Run is the world’s oldest and most prestigious 100-mile trail race. The race starts here in Squaw Valley and ends 100.2 miles later in Auburn. Western States, in the decades since its inception in 1974, has come to represent one of the ultimate endurance tests in the world.

Course Description

Following the historic Western States Trail, runners climb more than 18,000 feet and descend nearly 23,000 feet before they reach the finish line at Placer High School in Auburn. 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.

*Most of the trail passes through remote and rugged territory. People who are unfamiliar with the area should use caution when planning training runs, especially in the high country. Before leaving, let someone know where you will be running and when you will return.
