How it works
Runners race for 100m down the home straight of a 400m track. They start from blocks and run in lanes.
A reaction time – measured by sensors in the starting pistol and on the blocks – of less than 0.1 is deemed a false start and runners will be recalled, and the responsible athlete disqualified.
The 'stade' (192m race) was part of the Ancient Olympics.
In more modern times the 100 yards (91.44m) was adopted as the foremost sprint – it was part of the Commonwealth Games until 1966 – but the classic 100m distance, the Blue Riband event, has been part of the Olympics since 1896.
