Only a year after he started climbing Ignacio broke into eigth-grade sport routes. Rapid progression followed and soon Ignacio was ticking routes up to 8c+ and bouldering up to 8B+. In August 2015 Ignacio climbed his first 9a, making the first repeat of Pablo Barbero’s Clandestino at Teverga, Asturias. Just six months later he climbed his first 8C boulder, Nacho Sanchez's Entropía, at Castillo de Bayuela.
Ignacio is also a slab aficionado and has made a number of jaw-droppingly impressive ascents of technical slabs, including Pata 6 Baldosas, Inuït and El Tragador Oficial, all 8b+. In April 2017 he made the first ascent of Territorio Comanche in La Pedriza, which he graded at 8c+. Involving a total of 35 metres of tenuous granite climbing on gear and bolts, Territorio Comanche starts with a section of 7c+ climbing with no handholds, followed by a boulder problem through a roof before a desperate upper slab, and is certainly one of the most difficult slab climbs in the world.
Shortly after his successful redpoint of Territorio Comanche Igncaio saw the video of James McHaffie climbing Meltdown, in the Dinorwig slate quarries, and says that instantly “it was like an obsession to want to go do it”.
