Introduction to the 800-meter race:
The 800-meter race, also known as the 800-meter middle and long distance race, is one of the important events in the Olympic track and field competition. 1896, at the 1 Modern Olympic Games held in Olympia, Athens, Greece, the men's 800m officially became an Olympic track and field event.
In international competitions, all track events over 400 meters (excluding 400 meters) adopt a standing start. The starter's password is "take your positions". When all the contestants are ready to stand behind the starting line, they can fire their guns and start the game.
Appraisal of 800-meter race results:
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.
