I've used this a couple of times and it's really helped me combat an encroaching cold. I run it by distance for myself, once I made a mistake and it ran 2 and a half times...I was never so tired but I woke up the next day reaaly over whatever I had been fighting.
我用過幾次，它真的幫我對抗了感冒。我都是按距離跑的，有一次跑錯了，跑了兩圈半……我當時感覺特別累，但第二天醒來就感覺好多了，之前一直受的病痛都消失了。
