UCI Track World Championships, Men

The UCI Track Cycling World Championships are the set of world championship events for the various disciplines and distances in track cycling. They are regulated by the Union Cycliste Internationale. Before 1900, they were administered by the UCI's predecessor, the International Cycling Association (ICA).

Current events include: time trial, keirin, individual pursuit, team pursuit, points race, scratch race, sprint, team sprint, omnium and Madison, also known as "The American". Women's events are generally shorter than men's. Events which are no longer held include the kilometer time trial (men), the 500 meter time trial (women), motor paced events, and tandem events.

World championships were first held in 1893, in Chicago, under the ICA. They were for amateurs. Separate professional races were held from 1895, in Cologne. Amateurs and professionals competed in separate events until 1993, after which they raced together in "open" races. Championships are open to riders selected by their national cycling association. They compete in the colours of their country.

The winner of ICA championships received a gold medal. 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. Former champions can wear rainbow cuffs to their everyday jerseys.

World track championships are allocated to different countries each year. They are run by that country's national cycling association, although the top referees (President of the Commissaire's panel - PCP, Secretary, Starter, and Judge Referee) are International Commissaires appointed by the UCI.
