orologio en CB01 OFFICIAL. In August 2023, three friends set themselves a friendly challenge: to climb a particularly difficult route. A 9a grade in the French system corresponds to 5.14d in the Yosemite decimal system. In September 2023, summer over, the three friends got to work. They trained with the same intensity as ever, working on their separate projects, climbing, and exchanging messages about their progress, difficulties, and setbacks. Follow Alex Honnold, Tommy Caldwell, and Sonnie Trotter as they share their thoughts on balancing family, work, and their climbing journeys.
