Most outdoor tracks are 400 meters around, just a bit less than one-quarter of a mile. A standard running track is 400 meters long, with two bends and two parallel straights with identical radii. The interior part of the track typically fits all throwing events and a regular soccer field of 68 by 105 meters.
A 400-meter track measures 84.39 meters on each straight section and 115.61 meters along each curve. Each of the eight lanes on the track is 1.22 meters wide. The radius of the inside lane is 36.5 meters, and the track has an overall length of 176.91 meters, an overall width of 92.5 meters, with a total area of about 14,594 square meters. The fastest 400m sprint time is 43.03 seconds, held by Wayde van Niekerk of South Africa.
To build an outdoor track costs between $50,000 to $1 million depending on the surface type. A basic BMX track costs $20,000 to $30,000, while it costs $1-2 million per mile to build a new railroad track. Mainly there are three types of rail tracks: normal, high speed, and subway tracks. Generally, 80,000 square feet is needed to install an indoor track. In India, synthetic athletic tracks cost around Rs 2,500 per square meter. The UK has approximately 360 athletic tracks, most of which are 400 meters round.
In the US, constructing a 400-meter polyurethane track from scratch typically costs around $1 million, whereas resurfacing an existing track usually costs about $300 thousand.
