What is the dimension of a track in track and felid?

Answer 1

Most tracks are 400 meters around.

Some racks in the US are one Quarter mile (1320 feet / 440 yards) That is 402.34 meters.

Some tracks are odd distances due to local circumstances.

How do you know? Most tracks are marked for standard international running distances=400 meters. Look at lane 1 at the common finish line--that would be the thickest white line usually at the end of a straightaway. It might have black squares on the lane lines. If there is more than one line in lane 1 (corresponding to staggered start lines moving equidistant from each other as you get further from the inside of the circle), then it is not 400 meters. A single line that is the origin of one or multiple sets of staggered start lines, and it probably is 400 meters.
