The Wikipedia has the following information about this codepoint:
Rock climbing is a sport in which participants climb up, across, or down natural rock formations or indoor climbing 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, such as scrambling, bouldering, sport climbing, and trad (traditional) climbing.
Rock climbing competitions have the objectives of either completing the route in the least amount of attempts, the least amount of time, or attaining the farthest point on an increasingly difficult route. Indoor rock climbing is typically split into three disciplines: bouldering, lead climbing, and top roping.
