Track Cycling events can be roughly split into 2 disciplines – Sprinting and Endurance Sprint Events: Individual Sprint - This is a very tactical event in which riders try to outmanoeuvre their opponents. Sometimes riders will come to a standstill in an effort to make their opponent take the lead, which is the least advantageous position before the final sprint to the finish line. Team Sprint - This spectacular form of racing sees two teams start off on opposite sides of the track. It is raced by teams of three riders over three laps for Elite Men and two riders over two laps for Elite Women. Each rider leads for a lap before dropping back. Kilometre / 500m Time Trial - This is an individual time trial from a standing start. Elite Men race over 1km and Elite Women over 500 m. The competitor with the fastest time is the winner. Keirin - Keirin racing originated in Japan. Contested over 2 km, the field of three to seven riders follows a pacing motorbike at an increasing speed, all the while jostling for position. When the motorbike pulls off the track with two and a half laps to go, the battle begins to win the sprint to the finish.
