Alex Megos, Nalle Hukkataival, Stefano Ghisolfi, Andy Gullsten, and Marcello Bombardi take part in the 'Best Trick' competition for the 20th anniversary of the historic Bside climbing gym in Turin. One of the first bouldering gyms in Italy, it plays host to a new kind of bouldering competition: each of these superstars will set the hardest problem they possibly can, which the other athletes must then try and send.
