1 The athletes' track preliminaries are decided by drawing lots, and which runway is freely arranged by the computer. In the following rounds, the choice of the runway is based on the performance of the athletes in the previous round, and the final is generally determined by the preliminary results. The purpose of this rule is to make better athletes queue up on the middle runway. During the competition, the athletes go on their own tracks, and they are not allowed to cross the track after the start, otherwise the results will be invalid.
2 prone position starting and starting device must be used. After the password is issued, the player should immediately complete the relevant actions. Any player who fails to complete the relevant actions within a reasonable time is considered as the first foul (FS). In addition, after the password is issued, disturbing others with voice or action is considered a running foul.
When starting, any starting action before the gunfire rang is a starting foul. Starting from 20 10, it is stipulated that there is only one starting opportunity (starting before starting or starting within 0.02 seconds after starting), and the first race must be re-started. The athletes who start again will be disqualified and re-started.
The ranking of all runners in the race depends on the order of their trunks (excluding head, neck, arms, legs, hands or feet) when they reach the finish line, and ends along the vertical plane, with the first runner ranking first. If the result is the same, the athletes concerned should enter the next competition. In the final, the first place has the same score, and the referee has the right to decide whether to play again. If there is an unconditional rematch, tie for first place. As for other rankings, the results are the same and will be processed in parallel.
