TrailCon 2025 marks the launch of Ultrarunning’s Buckle Fever: Origins of the Western States Endurance Run—a book that chronicles the moment in 1974 when Gordy Ainsleigh dared to run 100 miles alongside the Tevis Cup horses. His audacious feat ignited a movement—and redefined the limits of human endurance. It became more than a race. It became a rebellion against doubt.
At its heart were co-founders, Mo Livermore and Shannon Weil (MoShan), two women who helped shape the race’s formative years, which lead the way for the worldwide sport of ultra trail running.
