100m sprint, long jump, rope skipping, shot put and 4 * 100m relay. What are the competition rules?

1. 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. At the time of departure, only one game is allowed (starting without the order or starting within 0.02 seconds after the order). The first game must be re-played, and the athletes who steal the race later will be disqualified and re-played.

2. Long jump: The competition result is the shortest distance from the jumper (stepping on the jumper is invalid) to the contact point between any part of the athlete's body and the bunker. In the preliminaries, the best result of each athlete's three attempts is the preliminaries, and the top eight athletes enter the finals.

Athletes who enter the finals can jump three times more to get the best results of the six trials in the preliminaries and finals to arrange the final ranking (when the two athletes have the same results, they will be ranked in chronological order).

3. Skipping rope counts, nothing special.

4. Shot put: The rules are the same as long jump (note: 1 It is invalid for an athlete to come out of the first half of the throwing field after throwing. I don't know the size of the venue, I hope the master will add)

5.4x 100 relay: 1 The starting rules are the same as 100 meters. It is not allowed to tamper with the track during the competition, and the relay must be in the relay area (the length of the relay area is unknown).

Not very detailed. I hope you can add it.
