Could be anything. Clicking under hard load or when sprinting is the bane of mechanic everywhere. Finding the soutce often boils down to a process of elimination. Start with the easiest. Switch the pedals and possibly the shoes out for another set, and ride. If you're lucky and that cures it, then you know it's the pedals, shoes or cleats. if it still creaks, you've eliminated three things on what could turn out to be a long list.
I'm not going to list all the possibilities, but you can search for threads using appropriate keywords. You shouldn't have trouble finding plenty of posts on the subject.
