Athletes must run on the track decided by their own lottery. If they run on someone else's track, they will be disqualified. If an athlete falls in skating, he can continue skating after standing, but he must not interfere with others' skating, otherwise he will be disqualified.
When entering, leaving and running in a corner, you are not allowed to touch or cross the snow line for the purpose of shortening the distance. Otherwise, you will be disqualified. If the athlete is affected by no fault of his own, he can be allowed to run again with the permission of the referee and get better results in his two runs. But if the skates are damaged or the rink is not clean, you are not allowed to run again.

1, switch runways
Athletes on the inner and outer runways must change runways when they slip into lane-changing areas. All events that start in the lane-changing area will not change lanes at the beginning. When the athletes of the inner and outer runways arrive at the lane-changing area and run at the same time, the athletes of the outer lane should be changed to the inner lane first, and the athletes of the inner lane must cross in front of the athletes of the outer lane before changing lanes.
2. Run on the same track.
When athletes run back and forth on the same track, the latter must keep a distance of 5 meters from the former, or surpass the former, but they must not run in parallel or with the belt, otherwise they will be warned, and will be disqualified if they commit another crime, and ordered to leave the track immediately.
The latter can surpass the former from the inside or outside, but it must not hinder the former. If there is a collision, the latter's admission qualification will be cancelled. However, when the latter wants to surpass the former, the former shall not hinder the latter's transcendence, otherwise the former's admission qualification will be cancelled.
