Anton Krupicka is a mountain runner living in Boulder, CO. He is a two-time Leadville 100 champion (2006, 2007), and a two-time USATF 50 Mile Trail national champion and course record holder (2009, 2010). In 2010, Krupicka finished second in the prestigious Western States 100, a race captured in the film Unbreakable. After breaking his leg in 2011, Krupicka began to diversify his mountain endeavors. In addition to racing, he started pursuing remote summits, long traverses, and ambitious link-ups in a single-push style that requires a unique combination of mountain running fitness and technical climbing competence. Krupicka alternates between life on the road, running and racing abroad, and living in the back of his Chevy S-10 pickup truck, The Roost, haunting the mountain ranges of the American west.
