was unable to climb a route without hanging on the rope or falling: a clean lead or send refers to someone climbing a route entirely under his/her own power without assist from the rope. Although not considered a proper, clean ascent if a climber does not do this in professional terms, a lower-level climber will have 'done' the route if he completed all the moves, even if it was 'unclean', i.e. rests or falls were taken (in this instance, it would be said that the route was 'dogged'). Access and conflicts The United States has a strong history of traditional climbing, especially at certain crags, and considerable value is placed on keeping routes the same as they were when pioneered by the first ascender. In the U.S. it is considered unacceptable to add bolts to an established traditional route to turn it into a sport climb. In the UK, a number of established routes have been bolted by sport climbers; this has generally been done in recent years by consensus with the first climber, though in earlier years this was not always the case. In Spain also, traditional climbs have been overbolted against the wishes of traditional climbers. In 2007, the British Mountaineering Council introduced 10,000 bolts into the UK climbing scene mostly to replace existing unsafe fixed protection. Bird watchers and other non-climbing rural visitors sometimes object to being distracted by brightly colored slings left at rappel anchors, which has led to climbers using webbing of the same color as the rock. Competition climbing Competition climbing is a form of sport climbing that takes place on artificial structures rather than natural rock surfaces. It has three different disciplines: lead climbing, speed climbing and bouldering. The latter is considered to be the most demanding of the three disciplines in terms of strength, co-ordination and agility. Sport climbing made its debut as an Asian Games sport in the 18th edition in Jakarta-Palembang, 2018. Olympics In September 2015, sport climbing was included in a shortlist along with baseball, softball, skateboarding, surfing, and karate to be considered for inclusion in the 2020 Summer Olympics; and in June 2016, the Executive Board of the International Olympic Committee (IOC) announced that they would support the proposal to include all of the shortlisted sports in the 2020 Games. Finally, on August 3, 2016, all five sports (counting baseball and softball together as one sport) were approved
