La Dura Dura9b+ (5.15c)

La Dura Dura is a short but brutally sustained sport route on the limestone of Oliana, conceived as one of the hardest single-pitch climbs in the world. Its sequences combine powerful, technical moves on small edges and pockets, demanding world-class finger strength and precision. The route drew intense international attention because it was worked by two leading climbers in tandem, and its eventual first ascent settled debates about the upper limits of single-pitch sport climbing at the time.
