You get very tired, and there was a certain amount of pain and you slow up. Your legs are so tired that you are in fact slowing. If you don't keep running, keep your blood circulating, the muscles stop pumping the blood back and you get dizzy.
你会感到很累，有一定程度的疼痛，然后你就会慢下来。你的腿太累了，实际上你正在减速。如果你不坚持跑步，保持你的血液循环，肌肉停止将血液抽回，你就会头晕。
