The 400 metres, or 400 metre dash, is a sprinting event in track and field competitions.
It has been featured in the athletics programme at the Summer Olympics since 1896 for men and since 1964 for women.
On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions
and race in separate lanes for the entire course.
