What is the function of the runway line? When he was running fast in physical education class at school, he ran on a field without a runway and hit someone. The teacher said that he didn't listen to the instructions. The function of the runway line is to distinguish the athletes' respective travel routes.

With the help of the runway line, the probability of physical contact between athletes can be reduced, and everyone can follow their own route, which greatly reduces mutual interference.

Running to the track can also improve the level of fair competition for athletes. With the track line, everyone's travel distance will be the same, and in the process of sprinting, they can also measure their real achievements. If there is no distinction between trajectory lines, the direction of most people will be curved.
