Olivier had been playing on the line for a long time (he was there when Vincent Pochon made the first ascent), but considered it too morpho for him until he saw Nico Januel's method.

As for the recipe, there is no real miracle: love climbing, want to push yourself and healthy lifestyle. [2, via google translate]

17 sessions since 2021, two dedicated seasons and multiple leg injuries. The first boulder that has kept me hooked for such a sustained period. A big fight even on the send, such a joy to battle through those slopes. Made up.
