City Climber in EdUHK

Rock climbing is a sport in which participants climb up, across, or down natural rock formations or artificial rock walls. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes.

Because of the wide range and variety of rock formations around the world, rock climbing has been separated into several different styles and sub-disciplines,[1] such as scrambling, bouldering, sport climbing, and trad (traditional) climbing another activity involving the scaling of hills and similar formations, differentiated by the rock climber's sustained use of hands to support their body weight as well as to provide balance.

Rock climbing competitions have the objectives of either completing the route in the least amount of attempts or attaining the farthest point on an increasingly difficult route. Indoor rock climbing is typically split into three disciplines. These disciplines are bouldering, lead climbing, and top roping.

Just before the First World War, there was a so-called "Mauerhakenstreit" (German: the Great Piton Debate of 1911) in Central Europe regarding the use of aids in climbing and mountaineering. Paul Preuss and Hans Dülfer were the main actors in these discussions, which have essentially continued to this day. Preuss propagated a pure climbing style. Angelo Dibona, on the other hand, was an advocate of security and was not fundamentally averse to pitons. When Luis Trenker asked how many pitons he had hit in total in life, Dibona replied: "Fifteen, six of them on the Laliderer north face, three on the Ödstein, two on the Croz dell 'Altissimo, one on the Einser and the rest on other difficult climbs."[4][5][6]

Aid climbing, climbing using equipment that acts as artificial handhold or footholds, became popular during the period 1920–1960, leading to ascents in the Alps and in Yosemite Valley that were considered impossible without such means. However, climbing techniques, equipment and ethical considerations have evolved steadily. Today, free climbing, climbing using holds made entirely of natural rock while using gear solely for protection and not for upward movement, is the most popular form of the sport. Free climbing has since been divided into several sub-styles of climbing dependent on belay configuration.
