Into the Wild meets Born to Run meets The Stranger in the Woods in a fascinating true story of a marathon-running hermit and a journalist’s quest to solve the mystery at the core of the enigmatic man’s existence.

When journalist Brett Popplewell first heard about Dag Aabye, an aging former stuntman who lived alone inside a school bus on a mountain, running day and night through blizzards and heat waves, he was intrigued and bewildered. Captivated by the seemingly implausible tale of a wild super-athlete aging more slowly than the rest of us, he was determined to meet the apocryphal white-haired man who was pushing the boundaries of the human mind and body beyond what anyone could dream was possible.
