Mountain-Bike

Mountain bike racing (shortened MTB or ATB racing) is the competitive cycle sport discipline of mountain biking held on off-road terrain. The Union Cycliste Internationale (UCI) recognised the discipline relatively late in 1990, when it sanctioned the world championships in Durango, Colorado. The first UCI Mountain Bike World Cup series took place in 1988. Its nine-race circuit covered two continents—Europe and North America—and was sponsored by Grundig. Cross-country racing was the only World Cup sport at this time. In 1993, a six-event downhill World Cup was introduced. In 1996, cross-country mountain biking events were added to the Olympic Games. In 2006, cross-country mountain biking events became part of the World Deaf Cycling Championships for the first time in San Francisco, USA.[1] In the United States, are three USA Cycling Mountain Bike National Calendars: Endurance, Gravity and Ultra-Endurance. USA Cycling runs the USA Cycling Mountain Bike National Championships. There are mountain bike racing types that are not recognized by the UCI, such as mountain bike orienteering that is governed by the IOF.
