There are all sorts of options when looking at a career in sport - coaching, sports psychology, sports science, biomechanics, data analytics, teaching are just some examples of the many different routes you can take.
In my opinion, the best way would be to research a few, select areas that interest you most, then contact a few companies/people asking if you could do some work experience with them. Experience is key to ensure that you will enjoy the roles that you like the sound of before actively pursuing them.
Another option is to focus on sports science at first, which covers various different aspects of sporting performance, then either continue into a sport science role, or choose to further your studies and specialise in one of the subjects covered as part of sports science.
Hope this of some help!
