I didn't win the prize in the sports meeting because I was afraid of being laughed at by my classmates.

They have no right to laugh at you. If you have the courage to take part in the sports meeting and challenge yourself, you have already won. The ultimate goal of participating in the sports meeting is not to get a ranking, nor does it stipulate that everyone should get a ranking, so ranking is meaningless. In short, ignore them, be yourself and be the coolest girl.
