A short history
BMX (Bicycle Motocross) began to take off in the late 1960s in California, around the time that motocross became popular in the USA. The sport was integrated into the organisational framework of the Union Cycliste Internationale (UCI) in 1993. Fifteen years later, BMX racing made its first appearance on the Olympic programme at the Beijing 2008 Games.
Riders launch themselves from an eight-metre high start ramp and race over a track comprising banked corners and obstacles such as jumps alternating with short pedalling sections. The event will start with an individual time trial run, with each rider racing the track once to determine the seeding for the next phase of competition. From the quarter-finals onwards, heats of eight riders will set off in a bid to get to the finish line first.
