The first three finishers in each discipline at the World Championships are awarded gold, silver, and bronze medals. The winner of each discipline is also entitled to wear the rainbow jersey in events of the same discipline until the following year's World Championships. Unlike other UCI-sanctioned mountain-bike races, the competitors in the World Championships represent national rather than commercial teams. The World Championships are usually held towards the end of the season.
History
The first UCI Mountain Bike World Championships took place in Durango, Colorado, USA in 1990 and featured only cross-country and downhill events. A separate UCI Trials World Championships had been held since 1986. From 2000 to 2016, the mountain bike and trials disciplines were combined and run as the UCI Mountain Bike & Trials World Championships. Beginning in 2017, the UCI world championships in trials will be run as part of the newly created UCI Urban Cycling World Championships.
