The total length of a standard runway is meters and should be composed of two parallel straights and two curves with equal radii. Except for grass runways, the inside of the runway shall be demarcated by a raised edge made of suitable material. The rim is about 1 cm high and at least 1 cm wide.
If part of the edge needs to be temporarily moved due to a field event, the original edge position should be marked with a centimeter-wide white line and plastic cones or small flags should be placed with a height of at least 10 centimeters and intervals of up to 10 meters. . This provision also applies to that part of the track in the meter obstacle course where athletes turn from the main track to cross the pool. For grass runways without sharp edges, the inner edge of the runway should be marked with centimeter-wide lines, and small flags should be placed at meter intervals. To prevent athletes from stepping on the line, the flag should be placed on the line, tilted toward the court, and at an angle to the ground. The size of the small flag is about 10cm. The length of the flagpole is 1cm.
The length of the runway should be measured centimeters beyond the outer edge of the inner edge of the runway. If there is no protruding edge, the measurement should be carried out centimeters beyond the outer edge of the marking line.
Note: The IAAF Track and Field Facilities Manual contains all technical information on track structural design markings. These rules give the basic principles that should be followed.
In all track events of meters and below, each athlete should occupy a lane. The minimum lane width is meters and the maximum lane width is meters. The lane line width is centimeters. All lane widths should be the same. The length of the first lane shall be measured in accordance with the provisions of the above paragraph, and the length of other lanes shall be measured centimeters beyond the outer edge of the inner lane line.
Note: The lane width should include the right lane line
