How many runways are there in a regular track and field stadium?

The total length of the standard runway is 400 meters, the runway curve is semicircular, and the radius of the innermost circle is 36 meters. Each runway is1.2m wide and there are 8 runways.

In the early 1960s, plastic runways appeared. In 1980s, the curve radius of track and field track was from 36 meters to 37.898 meters, and then developed to 36.50 meters. Experience shows that the radius of most 400-meter semi-circular runways should be 35 to 38 meters. IAAF suggested building a runway with a radius of 36.50 meters as far as possible.

The above three runways with different radii are collectively called "400-meter standard semi-circular track and field". At present, most of the venues used in all kinds of track and field competitions held at home and abroad are runways with the above radius.

On the Orientation of Track and Field Sports

Whether building a school track and field or building a public stadium, there are problems of coordination with other buildings. From the overall layout, we should pay attention to the following points when building a track and field:

1, the address should be convenient for drainage and water supply.

2. The location should be moderate and the transportation is convenient, which is convenient for people to use and watch the game.

3, overall beautiful, open terrain, fresh air, plenty of sunshine, there is enough space around.

4. The arrangement of the main venue and the auxiliary venue is reasonable, that is, the venue is close to the competition venue.

5. Reasonable arrangements can be made for the land used for various competition projects to avoid conflicts in the use process.
