Qualification for the Western States

Western States 100 – The Original Ultra Trail Race
Before the global trail running boom, there was the Western States 100-Mile Endurance Run – the race that started it all. Held annually in the Sierra Nevada mountains of California, the Western States 100 is recognised as the first 100-mile trail race in history. In 1977, the first edition of the Western States 100, only 14 runners took to the start line, and just one – Andy Gonzales – finished within the 24-hour time limit
