Czech athlete Adam Ondra making the first ascent of Change, the world's first 9b+

Adam not only made short work of the cave's established hard routes (including onsighting two routes graded 5.14c/8c+), he made the first ascent of Thor's Hammer (5.15a/9a+) and bolted a futuristic project out the steepest section of the cave. On October 4, Adam managed to link this 55-meter-long beast, establishing Change, the world's first route graded 5.15c/9b+. Along with his recent first ascent of La Dura Dura in Spain, Change stands as one of, if not the hardest route in the world. This is exclusive, never-before seen footage of Adam working and sending Change, which is a teaser from an upcoming film by filmmaker Petr Pavlíček.
