I run half marathon once a week.I will participate in the race 30km on January 16.I should be accustomed to running long distance.Every time I run half marathon,I learn a lot of things.
The beginning of the running my knees hurt.
During running in winter I often go to the restroom.
During running in winter I am very thirsty.
Yesterday I drunk a little,so today’s running was a little hard.
