Sports climbing refers to a style of climbing where climbers ascend routes with pre-placed protection in the form of bolts. The climber clips their quickdraws or carabiners onto these bolts as they progress, providing protection against falls. It is a popular form of climbing practiced both indoors and outdoors on routes specifically designed for sports climbing.
Lead climbing, on the other hand, is a technique used in various climbing styles, including sports climbing. In lead climbing, the climber is responsible for attaching the rope to the bolts or other forms of protection as they ascend the route. The lead climber carries the rope with them and places protection devices, such as cams or nuts, into cracks or pockets in the rock. The rope is then clipped into the placed protection, creating a safety system in case of a fall.
