An omnium (from Latin: of all, belonging to all) is a multiple race event in track cycling. Historically the omnium has had a variety of formats. In recent years, road racing has adopted the term to describe multi-day races that feature the three primary road race events.
The omnium was re-introduced into the World Championships as a five race format for men in 2007 and for women in 2009. The omnium was changed in 2010 by the UCI to include the elimination race and the distances of the events were lengthened to favour endurance cyclists.
The omnium replaced the individual pursuit, the points race, and the Madison at the Summer Olympic Games beginning in 2012. The change received some criticism from cyclist Rebecca Romero, who was left unable to defend her Olympic title.

- 4,000 metres for elite men, 3,000 metres for junior men and elite women, and 2,000 metres for junior women

For the first five events, each winner is awarded 40 points, each second place 38 points, each third place 36, etc. Riders ranked 21st and below will each be awarded 1 point. In the Points Race, riders add to and lose points from their totals based on laps gained and lost, and points won in sprints.
The winner of the Omnium is the rider who has obtained the highest total of points.
In the event of a tie in the final ranking, the places in the final sprint of the last event, the Points Race breaks the tie.
A rider must have completed every event in the omnium.
Road racing omnium
A road race omnium consists of a time trial, a criterium, and a mass-start road race - typically held across a weekend or other 2-3 day period. Points are awarded to the top finishers at each event and totaled at the end of the event. The overall winner for the event is chosen based on the number of accumulated points. Often, organizers will stipulate that riders must complete each event in order to qualify for the overall prize.
