The men's individual time trial event at the UCI Road World Championships is the men's world championship for the road bicycle racing discipline of time trial. Introduced in 1994 by the Union Cycliste Internationale (UCI), the world's governing body of cycling, the event consists of a time trial covering a distance of approximately 45 kilometres (28 mi) over flat or rolling terrain. Riders start separated by two-minute intervals; the one that completes the course in the shortest time is the winner, and is entitled to wear the rainbow jersey in time trial events for the forthcoming season.
