swim
Swimming is the first event of triathlon. The Sydney Olympic Games will set up a pontoon bridge, from which athletes will dive at the same time. They must follow the triangular route marked by buoys and ropes, and anyone who takes shortcuts will be punished. Athletes can swim in any position they like, but in fact all athletes choose freestyle.
Bicycle; Bicycle exercise
Athletes should immediately turn to cycling after landing from the water. In the cycling stage, the whole journey must be completed by bicycle. But if there is something wrong with the tire, the athlete can drive to the tire changing station to change the tire. Generally speaking, athletes must change their own tires, but the Sydney Olympic Games specially trained people to do this job. They were assigned to six tire changing stations along the track. Until 1995, cyclists were forbidden to use the airflow of the front runners in the Olympic Games because people thought it was unfair to the front runners. The rider must imagine a rectangle with a length of 10 m and a width of 3 m around it as an airflow area. They can't let their airflow zone overlap with other athletes unless they want to overtake. But law enforcement agencies find it extremely difficult to enforce this rule. So in 1995, they abolished this rule and let riders borrow wind from each other freely. But in reality, there is an unwritten rule among riders, which binds everyone not to borrow the wind. Anyone who breaks the rules will soon lose the respect of others.
long-distance run
The most important rule in the long-distance running stage is that athletes must finish all the races with their own feet. This one sounds obvious, but in some unforgettable triathlons, especially in the most difficult triathlon in Hawaii, once American Julie Moss finally climbed the finish line. This can't happen in the Olympic Games.
