The following is my experience, for reference only:
First of all, don't pursue how far you want to run at a time, just run every time, step by step, take time out to run every day, calculate how far you can run, and don't think about eating a fat man. If you can run 1000 meters at a time, there are two choices: one is to run one kilometer and speed up, and the other is to increase the distance at 65430.
Secondly, go running before going to bed at night. First, it's dark, you can't see the specific outline of the runway, and you won't feel pressure. On the contrary, it will run more and more easily and will not feel particularly tired. Second, the air at night is better than in the morning. It is recommended to run at night. Third, running at night is not easy to be recognized by acquaintances to avoid embarrassment.
Finally, warm up before running, that is, stretch your legs or something to avoid unnecessary strain.
I hope the above answers are helpful to you.
