Climbing legends Stefan Glowacz (Germany) and Chris Sharma (USA) team up to master a climbing route in the Majlis al Jinn cave in Oman. The route has never been attempted before and counts as the world’s longest roof climb with 13 pitches. Both athletes descended into the bowels of the earth into the giant Majlis al Jinn Cave to climb the probably biggest roof this planet has to offer. No one has taken on this challenge so far, the idea is unique. Glowacz and Sharma climbed from the bottom of the Majlis al Jinn Cave back to Earth’s surface.
