Sprint

400m

Description

Competitors run once around a 400m track. They start from blocks set in staggered positions 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. A runner can also be disqualified if he or she steps out of their designated lane.
