Day 3: omnium, keirin and madison
4) Individual pursuit: a four kilometres long race for men and three kilometres for women. A race between two riders who are selected based on their position in the overall after the elimination race.
5) Scratch: 15 kilometres for men and 10 kilometres for women. The rider to finish first wins the event.
6) Time trial: The ultimate event of the omnium in which men ride one kilometre against the clock and the women 500 meters. The participants start from a starting machine. Two riders race against each other based on their position in the overall after the scratch.
The classification in every event decides the amount of points the rider is awarded. The rider, who accumulated the most points after six events, wins the omnium.
The keirin is a sprint event with five to eight riders and takes place over eight laps. In the first five and a half laps the riders ride behind a pacer on a derny. These laps give the participants the opportunity to fight for a good position for the final sprint. The riders must stay behind the pacer until the pacers leave the track two and half laps before the finish. The road to the final takes several preliminaries and repechages. Depending on the amount of riders in the preliminaries, the first two or three participants advance to the next round. The event ends with a final in which the first rider to cross the finish after eight laps is the winner of the keirin event.
The madison consists of teams of two riders from the same country wearing the same colours. The maximum amount of teams on the track is 18. Only one of the riders participates in the race while the other rests actively higher on the track. The participants change positions regularly. The change occurs with a hand sling with which the rider that is going to rest propels the other one forward. During the race there are sprints every twenty laps with 5, 3, 2 and 1 points awarded to the first four finishers. The teams can also take a lap. The winner of the race is the team with the most laps. If there are several teams with the same amount of laps the team with the most points wins. The madison race for men takes 50 kilometres (200 laps).
