The world’s oldest 100-mile trail race, Western States has been testing runners since 1974 on a demanding point-to-point course from Olympic Valley to Auburn, California. The race covers 100 miles with over 18,000 feet of climbing and 23,000 feet of descent, following portions of historic trails used by gold miners in the 1850s.

Starting early Saturday morning, runners have 30 hours to complete the course, though the coveted handmade silver belt buckle goes only to those finishing under 24 hours. The terrain varies from wide dirt roads to remote, rugged single track accessible only by foot or helicopter. Roughly half the race runs through the night, making headlamps essential. A notable challenge comes at mile 78 with a river crossing that’s roped and staffed with volunteers on race day.

The course reaches its highest point crossing Emigrant Pass through the Granite Chief Wilderness before the long descent into Auburn. Twenty-one aid stations provide comprehensive support, with night stations offering hot soup, coffee, and chocolate alongside standard race fuel. Medical care is available at ten stations, staffed by physicians, nurses, podiatrists, and massage therapists.

Entry requires qualification within two years plus selection through the competitive lottery system. Over 1,500 volunteers create an atmosphere participants consistently praise, turning the grueling challenge into a community celebration. Finishers earn entry into ultra-running’s most exclusive club and qualify for both the UTMB World Series and consideration for the prestigious Grand Slam of Ultrarunning.

The race awards the Wendell Robie Cup to the first male and female finishers under 24 hours, with age group awards recognizing top performers across five categories.
