Where is the starting line of 200 meters, 400 meters and 800 meters?

According to the Drawing Sketch of IAAF 400m Standard Runway:

The starting lines of 200m, 400m, 800m (note: starting line) and 100m are the same, and they are all white paint lines with a width of 50mm and a length of170mm (the standard width of the runway is 1220mm, including lanes with a width of 50mm).

The difference is only the starting position: the starting position of 200 meters is in the third straight line (that is, the second bend), and the starting positions of 400 meters and 800 meters are in the first straight line (that is, the first bend is also behind the finish line); The 200-meter, 400-meter and 800-meter starts are all curves. 100 meters straight.

See attached drawings. Originally, I cut three soil sections, but unfortunately only one picture can be inserted here. If necessary, please contact my space email, and I will send you the full map for a detailed look. It is not convenient to leave your contact information here.
