Lead climbing is a technique popularly used by climbers attempting to navigate up a cliff face route. The technique works by the lead climber attaching themselves to an elastic climbing rope and then ascending the route. At key locations, the climber attaches protection devices including nuts, cams and quickdraws to ensure their safety if they fall. This technique also requires a second climber, acting as a belayer, to feed rope to the lead climber and to hold the rope in the event of a fall. Lead climbing is especially popular thanks to the speed at which climbers can ascend..
