Lead climbing is a climbing technique used to ascend a route. This technique is predominantly used in rock climbing and involves a lead climber attaching themselves to a length of dynamic (elastic) climbing rope and ascending a route while periodically attaching protection (quickdraws or traditional protection) to the face of the route and clipping into it. The lead climber must have another person acting as a belayer. The belayer has multiple roles: holding the rope in the event of a fall, and paying out or taking up rope as the climber moves.
