Traditional climbing

Traditional climbing, abbreviated to "trad", is a style of rock climbing in which routes are climbed from the bottom up, without using artificial aids to progress (just the climbers' hands and feet), and where protection is placed by the climbers as they ascend. It is a form of free climbing.

In the United Kingdom, "traditional" means that all protection is placed by the leader. In some other parts of the world, notably North America, a route may be described as "traditional" even if there are bolts already in place on the route, as long as these bolts were placed while on lead, rather than rappel, and only where absolutely necessary for safe passage.

Traditional climbing emphasizes the adventure aspect of rock climbing; as such it contrasts with sport climbing, which emphasizes the athletic aspect.
