Information:  - Track cycling is a bicycle racing sport usually held on specially built banked tracks or velodromes (but many events are held at older velodromes where the track banking is relatively shallow) using track bicycles.  - Xaver Kurmann ( born 29 August 1948 ) is a retired Swiss cyclist who won two Olympic medals in the individual pursuit event .  - The individual pursuit is a track cycling event where two cyclists begin the race from a stationary position on opposite sides of the track.  The event is held over for men and for women. The two riders start at the same time and set off to complete the race distance in the fastest time. They will ride on the pursuit line at the bottom of the track in order to find the fastest line. This race makes for a good spectacle as the two riders pursue each other attempting to catch the other rider who started on the other side of the track. If the catch is achieved, then the successful pursuer is declared the winner. However, they can continue to ride the rest of the race distance in order to set the fastest time in a qualifying race or a record in a final.
