UCI Cyclo-cross World Championships

The UCI Cyclo-cross World Championships are the world championships for cyclo-cross organised by the Union Cycliste Internationale (UCI). Starting in 2020, six events are organized each year – men's elite, women's elite, men's under 23, women's under 23, men's under 18 (Men's Juniors), and women's under 18 (Women's Juniors). Traditionally, the elite events are held on a Sunday with the other events held on the Saturday the day before.

The UCI awards a gold medal and a rainbow jersey to the winner. Silver and bronze medals are awarded to the second and third place contestants. World champions wear their rainbow jersey until the following year's championship, but they may wear it only in the type of event in which they won it.
