Danelle Ballengee, a world champion adventure racer, struggled to survive for three days and two nights after falling down a Utah canyon and fracturing her pelvis. The endurance athlete and four-time Pikes Peak Marathon champion had fallen 60 feet to the canyon bottom after slipping on an ice patch of ground while struggling up a rough portion of the path.

Unable to move and alone in a 1,000-square-mile wilderness, her sole hope for rescue rested with her dog Tasman (Taz). Ballengee relates her tragic survival story, which kept me on the edge of my seat.

Ballengee elaborates on her story in the longer video below.
