Take the initiative to apply to the coach I didn't do sports training in college, but I like middle and long distance running at school. Later, I found our coach, who was also introduced by my brothers and sisters in the Student Union. The coach won't say no right away. He is very diligent. If you are given a chance to enter, you must stick to it. Giving up halfway will make others very disappointed in you. Don't be discouraged even if your grades are not good. Believe that you are a dark horse. Haha, I got good grades in the competition when others were not optimistic.
