How large is a track in track and field?

Answer 1

The majority of running tracks measure 400 meters (437.2 yards) in length. They are usually laid out with each straight section 100 meters, and each turn 100 meters respectively. Some tracks are laid out with shorter straight sections and longer curves such as 90m straight and 110m curve. The longer the curve the less radius and therefore the faster you can run around the curve. Although most of the 440 yard (1/4 mile) tracks have been converted to metric dimension, there are still a few around, mostly at high schools in the U.S.

The length of a field track varies, depending on whether it is an outdoor or indoor track. Most outdoor tracks tend to be about 1/4 mile long/.4 km and indoor tracks are typically shorter.
