A synthetic track is composed of EPDM particles + polyurethane surface. Characterized by good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, it is conducive to effectively improving the performance of athletes and reducing fall injuries. Moreover, it is somewhat resistant to ultraviolet rays and aging, can be used under all weather conditions and is internationally recognized as fit for outdoor sports fields.

How long is a synthetic track in the stadium?

Generally 400 meters in a circle

First 87×+2×3.14×(36+1.2×0) =400

Second 87×2+2×3.14×(36+1.2×1) ≈408

third 87×2+2×3.14×(36+1.2×2) =415

Fourth 87×2+2×3.14×(36+1.2×3) ≈423 meters

Fifth 87×2+2×3.14×(36+1.2×4) ≈430 meters

Sixth 87×2+2×3.14×(36+1.2×5) ≈438 meters

The seventh 87×2+2×3.14×(36+1.2×6) ≈445 meters

Eighth 87×2+2×3.14×(36+1.2×7) ≈453 meters

In primary schools, the length of the track is generally 200 m. The radius of each curve is 16.7 m, while the length of each straightway is 46.8 m. There are four lanes: the minimum width of each lane is 1.22 m, the maximum is 1.25 m, and the width of the break line is 5 cm. All lanes should have the same width.

In secondary schools, the length of the standard track is 400 m. Each curve is semi-circular with a radius of 36 m at the innermost circle. Each lane is 1.2 m wide, and there are eight lanes.

The circumference of the inner circle is 400 m, and the radius of each curve should be 36.5 m. Each curve should have eight lanes whose width is 1.22 m, while each straightway should have 10 lanes.

The length of the safety zone on the inner side of the track should be no less than 1 m, and it is better to establish a safety zone with a length of 1 m on the outer side. The length of the starting area should be at least 3 m and the buffer area for final spurt should be at least 17 m. Both lateral and longitudinal inclination of the track shall not exceed 1:1000.

The standard synthetic track has a total length of 400 m. Each curve is semi-circular with a radius of 36 m at the innermost circle. Each lane is 1.2 m wide, and there are eight lanes.
