OMNIUM
The Omnium is a multi-discipline event introduced in the 2010 World Championships. The omnium consists of six disciplines: a 250-metre time flying lap time trial, a 40km points race (25km for women), a 4km pursuit (3km for women), a 15km scratch race (10km for women) and a kilometre time trial (500 metres for women) and an elimination race. Riders are awarded points depending on their finishing position in the first five rounds, which they they take into the final points race. During the points race, riders accrue more points – or drop points if they lose a lap. The omnium was introduced for the first time in an Olympic Games at London 2012.
