From lead to speed. A look at the disciplines of sport climbing
Sport climbing consists of three separate disciplines: speed, bouldering and lead.
Speed climbing is a race up a 15-metre wall, with the fastest climber winning.
Bouldering sees athletes climb a short wall — about 15 feet (4.5 metres) in the Olympics — without ropes but with a large foam mat below in case of falls.
Lead climbing is an endurance challenge that sees climbers try to reach the highest point on a tall wall, clipping into a rope as they go.
At the Tokyo Olympics, all three were part of a single combined event. For the 2024 Olympics, the speed discipline was split off into a stand-alone event with bouldering and lead combined as another event.
In Los Angeles in 2028, all three disciplines will be separate events.
