Lead climbing
Climbing while clipping protection into the rope as you go, so falls are longer than on top rope.
In lead climbing, the climber carries the rope up from the ground and clips it into protection, quickdraws on bolts for sport routes or cams and nuts for trad routes, as they ascend. Since there is no rope already anchored above, a fall means dropping roughly twice the distance above the last piece of protection plus rope stretch, rather than the short drop of a top rope fall.
This longer fall potential is why lead climbing calls for more from both the climber and the belayer, including confident clipping technique, careful rope management to avoid back clipping, and a belayer who gives an attentive, dynamic catch. Sport lead climbing on bolted routes and trad lead climbing on removable gear share the same falling mechanics but differ hugely in how reliable the protection is.
Most climbers move to leading only after building solid top rope belay experience and getting direct instruction on lead specific skills, ideally through a class or mentorship with an experienced leader. Fear of falling is normal and often improves with practice on routes that offer clean, well protected falls before pushing into more serious terrain.
