In modern life, because the pace of life is getting faster and faster, many people have basically never exercised. Although some people have a fitness card, it is difficult to go to the gym several times a year, and the problem of obesity is becoming more and more obvious. But obesity often leads to many health problems, such as hypertension and diabetes, so we must keep a certain amount of exercise every day and control our weight. In daily life, five kilometers is a very common running distance, and basically everyone can complete it. In order to keep healthy, it is a good choice to run five kilometers every day. It is worth mentioning that some fitness enthusiasts divide the five-kilometer running level into ten levels according to the speed of five kilometers. Let me introduce these ten levels to you respectively.

The first is the "walking level", which is the slowest level, usually between 40 minutes and an hour. This speed is basically walking, which is very suitable for old ladies and gentlemen with clumsy legs and feet. Of course, for obese people, this level is also possible.

The second is "entry level". The entry level is usually a person who runs five kilometers in 35 minutes to 40 minutes. Most of them are just runners. Because I didn't run much before, my running posture was incorrect and my physical fitness was average, so I wouldn't run too fast.

The third is the "runner level". This kind of person's five-kilometer running time is between 30 minutes and 35 minutes, and the speed is not very fast. Most people's best running speed is this level, and they can see the scenery while running, which is a very good running speed.

The fourth is "hard work level". The hard-working five-kilometer running time is between 25 minutes and 30 minutes, which is also the threshold for most amateur runners. Maybe many people will stay in this place for a long time. If they want to continue to improve, they will have to exercise hard.

The fifth is the "gradual level", which takes 20 to 25 minutes to run five kilometers. For the amateur level, this is already very strong, and many people are discouraged from reaching this level. For female athletes, a score of about 20 points is basically regarded as a national second-class athlete.

The sixth kind is "Amateur God", which requires runners to run for 20 minutes. This is not an easy time, and it takes a long time to persist. Some people can't run for 20 minutes in their lifetime.

The seventh is "national level". Men and women have different requirements, requiring male runners to run 14 minutes and 40 seconds and female runners to run 17 minutes and 29 seconds.

The eighth category is "athlete level". For men, the minimum requirement is 14 minutes 15 seconds, and for women, the minimum requirement is 16 minutes and 30 seconds.

The ninth category is "National Athletes Class". The minimum requirement for men is 13 minutes 3 1.4 seconds, and for women it is 15 minutes 54.7 seconds.

The tenth is the "world record". At present, the men's world record is 12 minutes 37.35 seconds, and the women's world record is 14 minutes10/second 15.

Because I don't run much, running five kilometers is barely an "entry-level"
