But in fact, if a person can run two kilometers in a row at this speed, it will actually take him less time to run one kilometer alone, so it is no problem to pass the above score.
Don't try to touch the rhythm of 3:30-5:00 when practicing 1000. First of all, the interval of 400 meters is 2-3 times a week. About 400 meters interval 1:20, rest for 2 minutes, 5 groups in a row. It was really hard to run at first, and the third group had no strength, so it was very uncomfortable after running. But I have to say that intermittent running is really helpful to improve the speed endurance of 1000 meters.
I've practiced it ten times. Now the basic group 400 can run 1: 14, and the five groups are not particularly tired. The other time is 5km5 to distribute jogging, aerobic exercise and fat reduction. Then one day, I found that after running five kilometers at 4:55, I tried to sprint 800. According to the time, 800 took 2:35. The pace of the last 6 kilometers is 4:40, which is much more comfortable than the previous 4:30.
So the suggestion for everyone here is that you can jog intermittently. If you jog, just run 5 kilometers in 25 minutes. If you can't run 400 intermittently, start at 200, which is exactly 200 to 200, which is very convenient.
Believe me, the intermission has made great progress for 1000. Now running 1000 has also changed from the previous running posture. In the past, they were all rushing into the crowd, and their posture was deformed from beginning to end. Now at three o'clock, with the Chongge 800, the body is basically stable, the running posture will not change, and the core strength will also be improved.
