He is a tireless climber, route developer and rebolter who has left his mark not only on the walls of La Pedriza, but also in Cuenca and other crags such as El Fin del Mundo. For more than two decades he has opened new lines on both granite and limestone, and has played a key role in the maintenance and modernisation of dozens of routes, working alongside federations, park authorities and local climbing groups. His technical skill, ethical approach to bolting and passion for making the rock accessible to the community have made him an essential figure in La Pedriza and its surroundings. Without him, his sayings and many of his mad yet brilliantly practical ideas, La Pedriza would not enjoy such a thorough rebolting effort.
