60 metres, or 60-meter dash, is a sprint event in track and field. It is a championship event for indoor championships, normally dominated by the best outdoor 100 metres runners. At outdoor venues it is a rare distance, at least for senior athletes. The format of the event is similar to other sprint distances. The sprinters follow three initial instructions: 'ready', instructing them to take up position in the starting blocks; 'set', instructing them to adopt a more efficient starting posture, which also isometrically preloads their muscles. This will enable them to start faster. The final instruction is the firing of the starter's pistol. Upon hearing this the sprinters stride forwards from the blocks.
