You can find out a great deal about Sports Psychology courses on the UCAS website. I think that some of the search results I've just looked at might 'time out' so, rather than posting direct links, I'll tell you how to find the information:
Go here:
http://www.ucas.ac.uk/search/index07.html
Click 'Subject Search'
Click letter 'S'
Click 'Sport Science'
Click 'All Sport Science Courses'
Now look through the list for those that include psychology. (Many courses have titles such as 'Sport, Health and Physical Education with Psychology' rather than just 'Sports Psychology). You might find using 'Edit > Find' will help here.
Choose a course title which looks as if it might interest you. (Check that it's got 'EP' alongside it. That means that there's a complete 'entry profile'). Click on it (preferably holding down Shift, so it opens in a new window), then check out the links such as "Is this course right for me?"
The information provided by each institution varies but, by looking through a few different courses , you'll find out a great deal about the course details, entry requirements and possible career opportunities.
Hoping this helps,
Chris
