Sport is played between college teams, in tournaments known as cuppers (the term is also used for some non-sporting competitions). In addition to these there are higher standard university wide groups. Significant focus is given to annual varsity matches played against Cambridge, the most famous of which is The Boat Race, watched by a TV audience of between five and ten million viewers. This outside interest reflects the importance of rowing to many of those within the university. Much attention is given to the termly intercollegiate rowing regattas: Christ Church Regatta, Torpids, and Summer Eights. A blue is an award given to those who compete at the university team level in certain sports. As well as traditional sports, there are teams for activities such as Octopush and quidditch.
