Watch VoirFilms. Adam Ondra climbs two of the world's hardest boulder problems, suggesting V16 / 8C+ for both. First, Terranova, an extremely funky traverse at his home area near Brno, Czech Republic. Then Gioia, a problem in Varazze, Italy put up by Christian Core in 2008 and only repeated by Adam. Music by Abel Okugawa, Gramatik, The Gaucho and the Gremlin, and Talvihorros.
