Why is the total length of the marathon this number?

This data depends on which game. Then look at which country, which region.

And I feel that it should be an upward trend in recent years.

The marathon originated in ancient Greece in 490 BC. According to legend, the Greeks and Persians fought a war in the Greek town of Marathon, and the Greeks emerged victorious. In order to bring the news of the victory to Athens, a warrior named Felibus was sent to run from Marathon to Athens.

He arrived at his destination exhausted and died after reporting the news of the victory. In honor of Felibus, in 1896 at the first modern Olympic Games, a long-distance race from the town of Marathon to Athens was held, which was named the Marathon.

The standard distance of the World Marathon is now 40.195 km, which was determined by the 4th London Olympic Games. Many marathons around the world are the only athletics events where the world's top athletes and amateurs compete together, so marathons have developed extensively. The Boston Marathon, which began in 1897, is the oldest city marathon.

Founded in 1970 after Boston, the New York City Marathon was founded with more than 100,000 runners at its peak. Born in 1981, the London Marathon is the city with the most best men and women in history. The marathon held in the small Dutch town of Rotterdam in April is also famous all over the world.

In honor of a warrior named Felibus, the distance from the Greek town of Marathon to Athens is kilometers. Therefore, the total length of the marathon is set as kilometers.

The marathon is a very popular long-distance running event in the world, with a distance of 26 miles and 385 yards, which is converted into kilometers (also said to be kilometers).

The marathon is a long-distance running event with a distance of kilometers (also known as kilometers). Why isn't the distance of this event an integer? This begins with a battle that took place on September 12, 490 BCE.

The battle was fought by the Persians and Athenians on the shores of Marathon, not far from Athens, and the Athenians eventually won a victory against the invasion. In order to let the people of his hometown know the good news of the victory as soon as possible, the commander Milletti sent a soldier named Phidipides back to report the news.

Phidippides was a well-known "Scud", and in order to let the people of his hometown know the good news, he ran as fast as he could, and when he reached Athens, he was out of breath and said only "We have won!" And he fell to the ground and died. To commemorate this event, the marathon was established at the first modern Olympic Games in 1896, and the distance of the race was measured in kilometers - the distance of the Fidipiles to deliver the letter.

Due to the large amount of exercise, the requirements for the cardiovascular system, locomotor system, respiratory system, etc. are particularly high. Marathons are not recommended for the following people:

a.People who have not undergone a comprehensive physical examination.

b.People who have not been systematically trained.

c.People who experience moderate chest pain and angina pectoris while doing light activities.

d.People who have had a heart attack in the recent past.

e.People with rheumatic heart disease and people with congenital heart disease.

f.People with high blood pressure or other heart disease, myocarditis.

g.People with severe arrhythmias.

h.Diabetics with high or low blood sugar.

i.People who take antihypertensive drugs and still have blood pressure over 140 to 90 mm Hg.

j.People who are too obese.

In addition, the elderly should participate in marathons according to their means. The elderly have a relatively high incidence of various diseases, especially the cardiovascular system, due to the gradual decline of various functional organs of the body with age. Therefore, when participating in running, you must arrange the amount of exercise according to your specific situation, choose the appropriate way to do it, and do not rush it.

After understanding, it was found that most of them were caused by coronary heart disease and myocarditis, which must not be blamed on marathon sports. The marathon itself does not cause death, it is mostly due to an underlying medical condition, so it is necessary to have a detailed physical examination before participating in the race.

Relevant experts pointed out that the following situations are not suitable for people to participate in the marathon:

1) Those who have not been systematically trained are not allowed to participate in the competition.

b) If you feel moderate pain in the chest and severe coronary artery disease (angina) when doing light activities.

3) People who have recently had heart disease.

4) People suffering from rheumatic heart disease and people with congenital heart disease, especially those whose face is pale and blue during exercise.

5) People with high blood pressure or other heart disease or myocarditis.

6) Severe arrhythmia.

7) Diabetic patients with too high or too little blood sugar.

8) Those who have taken antihypertensive drugs and still have blood pressure of more than 180 110 mm Hg.

9) Those who are too obese.

Most people who do not have heart disease can participate.

The distance of the marathon is the same length, regardless of men, women, youth, teenagers.

There is a half marathon.
