Running TrackThe all-weather running track is a rubberized artificial running surface for athletics. For competitors, it provides a stable surface on which to test their athletic abilities without the adverse weather conditions interfering. Historically, various forms of soil, rocks, sand, and crushed cinders have been used. Many examples of these types of trucks still exist around the world.Get more news about high quality running track,you can vist our website!Measurement of a track
A good length for the first lane of a competition running track is 400 m (1,312.3 ft). Some tracks are not built to this specification and instead are legacy Imperial distances such as 440 yards (402.336 m). Distances in imperial units were still used in the United States until the rule was changed in 1979. Some facilities build tracks to fit the available space. One of the most notable examples is Franklin Field, where lane 4 achieves a distance of 400 meters. The Olympic tracks in the early 20th century were of other lengths. Each lane of a truck could be up to 122 cm (4.00 ft) wide (by IAAF regulations), but most American trucks are built to NFHS high school specifications and have small lanes. The IAAF also specifies a recommended radius of 37 meters for turns, but allows ranges. World records can be set at less than 37 meters exactly, provided major international competitions are held and within legal limits.
Lane measurementLane – Lane ordinal with the first lane inside Length – Total length of the lane Radius – The radius of the curve 0.30m from the inside of that lane Semicircle Length – Length of track semicircle at that radius Delta – The length of the track at this radius is longer than the track inside the 200m race (so how much lead-in is needed to make it a fair race) Angle – Corresponding stagger angle (starting from this offset ensures racers in that lane travel the same distance on curves).
