The Union Cycliste Internationale (UCI) recognised the sport of mountain bike racing relatively late in 1990, when it sanctioned the world championships in Purgatory, Colorado. The first mountain biking world cup series took place in 1991. Its nine-race circuit covered two continents—Europe and North America—and was sponsored by Grundig. In 1992, the Grundig-UCI world cup circuit expanded to ten races, and remained a trans-Atlantic series. Cross-country racing was the only world cup sport at this time, then in 1993 a six-event downhill world cup was introduced. In 1996, cross-country mountain biking events were added to the Olympic Games. NORBA refers to the Board of Trustees that represent the sport of mountain bike racing for USA Cycling. There are three USA Cycling Mountain Bike National Calendars: Endurance, Gravity and Ultra-Endurance. USA Cycling runs the USA Cycling Mountain Bike National Championships. In 2006, cross-country mountain biking events became part of the World Deaf Cycling Championships for the first time in San Francisco, USA. There are mountain bike racing types that are not recognized by the UCI, such as mountain bike orienteering, that are governed by the IOF.
