Pringle's autobiography offers a graphic and often painful account of his experiences with major marathons, including the Marathon des Sables and the Yukon Arctic Ultra. Journalists and scientists monitor his progress as he pushes his body to the very limits, as he competes in extreme sporting events which have already claimed lives. A growing sense of self-knowledge and a sense of unity with the natural world lead him to overcome his inner demons, and to find a distinctive and transformational spiritual path.
