In the summer of 2017, Alberto Zerain was working on the 2x14x8000 project. The project was spearheaded by Juanito Oiarzabal, who aimed to see 14 of the world's 8,000 m. peaks climbed twice. Part way through, Oiarzabal's health declined. Zerain then met up with Mariano Galván to finish the project. In June 2017, they were both attempting to summit Nanga Parbat via the Mazeno Ridge route.
