Didier Berthod

[3] In 2005, Berthold returned to do the route without any pre-placed protection,[3] and Greenspit was recognized as one of the hardest traditional crack climbs in the world.

[2][4][5] Berthod then made trips to America where he put up new traditional climbing routes such as Learning to Fly and From Switzerland with Love, both at grade 5.13+ in Indian Creek in Utah.

[2][5] The film also documented Berthod’s other climbs in Europe (including Greenpoint), and his frugal lifestyle such as working in a hostel between attempts.

[9][10][11] In May 2024, Berthod returned to Cobra Crack to make the 20th ascent of the route saying "It is more so the end of a book, than a chapter".

[12] After completing First Ascent, Berthod, then aged 25 and carrying a serious knee injury, decided to completely abandon rock climbing and joined Nicolas Buttet [fr]'s Franciscan-community, the Eucharistein [fr] fraternity, in Saint-Maurice, Switzerland (close to where Berthod was born),[6] as a monk.
