First, the principle of track grouping: try to make each group equal in number when grouping. In the preliminaries, athletes of the same unit should try to avoid being in the same group (there are many short-distance running events and few groups, except for long-distance running events that are not grouped). When there are too many people in long-distance running events, they can compete in groups, and the number of people in each group shall not exceed 15. When there are registration results, they are grouped in a serpentine arrangement according to the registration results. When there is no registration result, you can use the table diagonal method to group. The determination method of the number of games, the number of groups, the number of people in each group and the number of subsequent games after admission should refer to the relevant provisions of the latest edition of the Track and Field Rules. Second, the grouping principle of field events: field events are generally not grouped, and the order of athletes' competitions is determined by lottery. If there are too many participants, a qualifying tournament can be held, and the order of participating in the qualifying tournament will be determined by drawing lots. III. Competition schedule principle: 1. Between all-around events and track events, it is necessary to ensure that athletes have a certain rest time. 2. According to the general rules of concurrent projects, try to arrange related projects separately to reduce the conflicts of concurrent projects. 3. For similar projects, try to consider the sequence of competitions. For example, generally first 1 meter, and then 2 meters; 5 meters first, then 1 meter; Long jump first, then triple jump and so on. 4. The same field events of different groups are generally arranged in the same unit discontinuously. However, the same track event in different groups should be connected, such as men 1 m and women 1 m. If there are few short-distance races, it is best to arrange to finish the race on the same day. 5. Hurdling events are generally arranged in the first item of each unit, and can also be arranged after long-distance running and race walking. 6. Don't arrange two long throw events at the same time. 7. Pole vault competition should consider the direction of sunshine and the long time needed, and it is best to arrange it in the early morning. 8. It is best to arrange the last event of each unit in the relay race, so as to ensure the participation of multi-event athletes. 9. Before the end of the last unit, long-distance running can be arranged or the number of events can be reduced appropriately, so that the total score of the group can be announced and awards can be awarded at the closing ceremony. 10. Arrange the venue projects to prevent one end of the venue from being too concentrated and the other end from leaving the venue empty and ignoring the audience. 1 1. Try to complete track and field events in each unit at the same time. 4. On-site track events arrangement principle: After receiving the track record form, the athletes participating in the next competition can be admitted according to the method of score or ranking+score. Then the admitted athletes are sorted according to their scores, and then divided into prescribed groups according to the snake method, and the technical representatives are invited to draw lots. First draw lots to determine the number of groups, and then draw lots to arrange the time of each group of athletes.
