Austrian climbing legend Jakob Schubert sets his sights on two of the most coveted test pieces in the United States: Shaolin, a V17 / 9A boulder problem at Red Rocks, and Duality of Man, the hardest sport route in America and only the fourth climb in the world to be graded 9c / 5.15d. In this 21-minute film, Schubert documents his journey to Arizona to get his hands on Duality of Man, offering a rare inside look at what it takes to attempt the outer limits of human climbing performance. What makes this film exceptional is the access it provides into the mind and methods of one of the world's most accomplished competition and outdoor climbers as he squares up against America's ultimate redpoint challenge. Beautifully filmed and edited by Michael Piccolruaz and backed by Mammut, this is essential viewing for anyone who wants to understand what pushing the absolute frontier of sport climbing really looks like.

I recently went on a climbing trip to the U.S. with the goal to try two of the hardest climbs in the world: 'Shaolin', a 9A / V17 boulder in Red Rocks and 'Duality of Man', the hardest route in America and the 4th route in the world graded 9c / 5.15d. Follow along as I make my way to Arizona to get my hands on this test piece. Filmed and edited by Michael Piccolruaz Supported by @mammut
