If you are tired of running, slow down, but never stop or run away.
Physical strength has recovered a little. Hurry up, but not too fast.
Set a goal and increase the distance every day. A little further.
Run every day, not for a month, and ensure that you can run a marathon. Of course, there is nothing wrong with my health, because I am very tired. If you are in poor health, you may be damaged, but if you are in good health, you will definitely feel better and better.
Be careful not to gulp down water, drink it one mouthful at a time, and don't drink too much at a time, otherwise it will be dangerous and prone to sudden heart problems.
Relax while running and believe that you are okay. Stretch your breath, don't rush. Slow down if you can't run, but never stop. You will feel that you can speed up in a minute or two at most.
Breathing control is the key, stretching deepens.
