Ranking rules:
100-meter run: The athletes draw lots in the preliminary round of the venue, and the final round is generally decided by the preliminary round. 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. When starting, only one race is allowed (starting before starting or starting within 0. 1 second after starting). The first game must be restarted, and the athletes who start later will be disqualified and start again.
In track and field competitions, the ranking of all runners depends on the order in which their trunk (excluding head, neck, arms, legs, hands or feet) reaches the finish line and ends along the vertical plane, and the first runner ranks first. In any competition, if the athletes' scores are equal when they enter the next competition according to their scores, the referee of the terminal camera should consider the actual scores of the athletes concerned11000 seconds.
If the result is still the same, the athletes concerned should enter the next competition. If the actual conditions do not allow, we should draw lots to decide who will enter the next game. 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.
