In Part One I covered the very early history of the sport of endurance riding from 1814-1954 when forgotten individuals established the sport they called "endurance riding" and paved the future for the sport. In Part Two I covered the early history of the Western States Trail Ride (Tevis Cup) from 1955-1970 and worked through some folklore about the history of the Ride. In this concluding part we will wade through some controversy and get to the ultrarunning fun, the founding of the Western States Endurance Run or commonly called, the Western States 100.

By 1970 with all the numerous endurance rides held across the country, the Western States Trail Ride, or “the Tevis” had emerged as being the toughest and the premier endurance ride in the country. It had survived intense criticism over the years from the public and animal rights groups. Under the leadership of Wendell Robie, the ride had made adjustments, weathered the storms of criticism, and increased in popularity.

By 1970 among the dozens of endurance rides, there were still only a few that patterned their event after the Western States Trail Ride, Virginia City 100, and two 50-milers in California, Castle Rock 50 and Blue Mountain 50. In 1971 two more were established, Big Horn 100 in Wyoming, and Diamond 100 in California which awarded a Wendell Robie Cup.
