Track cycling disciplines at the Olympics:
Two riders compete over three laps in a best-of-three series of knockout races. Riders try to avoid showing their cards too early so the opening lap often takes place at a snail's pace as they try to psyche each other out.
On the final lap, riders look to steal a march on their opponent as they blast away for a furious sprint finish.
MEN: Gregory Bauge (France), Jason Kenny (Britain)
WOMEN: Victoria Pendleton (Britain), Anna Meares (Australia), Guo Shuang (China), Simona Krupeckaite (Lithuania)
Men over 4km. Women over 3km.
Two four-man or three-woman teams start on opposite sides of the track. The aim is to catch the opposition team or complete the race in the fastest time. Each rider takes it in turns to lead for half or, if they are up to it, a full lap.
MEN: Britain, Australia
WOMEN: Britain, Australia
Men: two teams of three riders compete over three laps.

WOMEN: Germany, Australia, China, Britain
Men and women over 2km.
Originated in Japan where it became very popular as a betting sport.
Six riders follow in the slipstream of a pace-setting motorbike, or "derny", which accelerates to a speed of up to 50km/h (40km/h for women) before pulling off the track with two-and-a-half laps to go leaving the riders to battle it out in a sprint to the finish.
MEN: Chris Hoy (Britain)
WOMEN: Anna Meares (Australia), Guo Shuang (China), Clara Sanchez (France), Victoria Pendleton (Britain)
