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 (pictured) in time trial events for the forthcoming season. Switzerland's Fabian Cancellara (2006, 2007, 2009 and 2010) and Germany's Tony Martin (2011, 2012, 2013 and 2016) have won the most competitions with four each. Australia's Michael Rogers (2003, 2004 and 2005) comes in next in terms of victories, with three wins; Rogers and Martin are the only people to take 3 wins in successive years. The current male champion is Italian rider Filippo Ganna, who won the 2021 event. (Full list...)
