Details are as follows:
1, classification: Marathon is a very popular long-distance race in the world, which is divided into three types: full marathon, half marathon and quarter marathon.
2. Rules: In the marathon, water and other drinks are provided at the beginning and end of the race, and there is a drink station every 2.5 kilometers along the race route. Water and drinks should be placed where athletes can easily get them when they pass by. Athletes can also bring their own drinking water, and they can set up drink stations where they need it. Drinking water and wet sponge supply stations are arranged between two beverage stations. There, long-distance runners and race walkers can get drinking water when they pass by, and they can also squeeze water from the sponge to wash their hair, which plays a role in cooling down. In addition, athletes can't get drinks from other places on the competition route.
It can be said that "water" is the most rigorous part of the marathon. In addition, athletes can compete along the correct route under the supervision of the referee. If there are special reasons, they can leave the competition route under the supervision of the referee, but if they leave without supervision, they will be disqualified.
Extended data
Marathon originated from Persia-Persian War. The battle was fought by Persians and Athenians at the seaside of Marathon not far from Athens, and the Athenians finally won the victory against aggression. In order to let the people in his hometown know the good news of victory as soon as possible, Commander Mi Leide sent a soldier named Fidi Pitts back to tell the news.
Freddie Pitts is a famous "Scud". He has been running in order to let his hometown people know the good news earlier. When he ran to Athens, he was out of breath and shouted excitedly, "Athenians, let's have fun, we won" and fell to the ground and died.
In order to commemorate this event, in the first modern Olympic Games held in 1896, a marathon was set up, and the distance of the marathon was 42.193km, which was run by Fedipintz messenger that year.
