The best way to write about your sports achievements on your CV is to focus on information related to the job you want.
For example, if the job advert you’re responding to notes that the employer is seeking someone who values teamwork, write about how you worked with your teammates to achieve a common goal, rather than emphasising your personal statistics.
Here are some good examples of how to write about sports achievements on your CV:
