British climber Hamish McArthur succeeds in repeating one of the most difficult boulder lines in the world: Megatron (9A).

At least since his participation in the 2024 Olympic final, Hamish McArthur also known to a wider audience. In recent months, the 22-year-old climber has presented lines such as Big Z (8C+) or the flash ascent of Frontside (8A+) proves again and again that he belongs to the top league in bouldering.
