What is the size of an athletic track in meters?

Answer 1

Virtually all athletics tracks are 400 metres long. This is why they have a staggered start in 400m races. An 800 metres race is therefore 2 laps of a 400m track.

Answer 2

The diameter of the inside lane of an athletics track is 400 meters. Of course, lanes further out have a greater diameter. This is why the start of 200 and 400 meter races is staggered.

Answer 3

400 meters
