The curve radius of 1 and 200m elliptical runways is from 15.00m to 2 1.50m, preferably 20.50m IAAF suggests that all new runways should be built according to the following regulations, and call them' 200m standard runways'.
2. It is necessary to carry out control measurement and record readings at 28 points. The average deviation shall not exceed+0.04m and shall not be less than 0.00m. ". When recording any event of 200 meters or more, the circumference of the track used for recording shall not exceed 202.30 meters (220 yards).
3. The maximum left-right inclination of the runway shall not exceed 1: 100, and the downward inclination of the running direction shall not exceed 1: 1000.
4. The width of all lanes is 1.22m( 0.0 1m+0m). The 200m standard runway has 4 lanes, 2 lanes or the unusual 1 lane.
Extended data
The size of the runway of the 400-meter track and field stadium
The standard track and field is a semi-circular 400-meter runway. When the radius of internal bend is 36m, the length of two bends is 228.08m, the length of two straight bends is 17 1.92m, the radius of inner channel is 37.898m, the length of two bends is 240m, and the length of two straight bends is 160m.
On the inner edge of the runway, a "bump" with a width of not less than 5cm and a height of 5.0-6.5cm should be built. If no bump is built, a sign line with a width of 5cm should be drawn.
The lane width is l.22m (or 1.25m), of which the lane width is 5cm. The standard track and field is a semi-circular 400-meter runway.
