Katherine Choong, the first Swiss climber to complete a 9A route, decided to repeat this performance in the Bernese Alps with "Jungfrau Marathon". For her, to repeat with such a performance represents much more than a sporting feat. Climbing is her school of life, a true philosophy. No matter how long it takes to achieve this extraordinary new achievement, she transforms frustration into patience, failure into solution, and once again, the dream into reality.
