Adam Ondra’s ascent of Soudain Seul 9A/V17 is a testament to his longevity and consistency. The sit start adds a V12 sequence of sloping rail moves, requiring intricate footwork, intense core tension, and strategic kneebars before linking into the relentless compression of The Big Island.
The upper section demands wide double heel hooks and full-body engagement to squeeze slopers while maintaining enough energy for the final push. Balancing efficiency and power is key—wasting strength on the opening moves can make the crux unbearable. With its blend of subtle technique and raw force, Soudain Seul remains one of bouldering’s ultimate tests.
