wind * * *.

Pay attention to the weather for long-distance running in winter. There is a lot of fog in winter. Remember not to exercise in the fog. The fog contains harmful substances such as acid, alkali,

sports drinks containing vitamin c should be supplemented several times in small quantities during transportation.

After long-distance running in winter, don't stop immediately, but jog for a while, because the blood is concentrated in the lower limbs at this time,

If you stop suddenly, the blood can't fully flow back into the heart, which will cause "gravity shock".

We should also pay attention to keep warm in time, ensure sleep, and promote fatigue recovery by means of * * * and hot bath.
