The Varsity Polo Match is an annual polo match between the Oxford University Polo Club and the Cambridge University Polo Club, played between teams of four players. Historically it was known as the inter-University Challenge Cup or inter-Varsity polo match. It is also known as the University Polo Match or by a title that includes the name of its current sponsor. Members of both teams are traditionally known as Blues, with Oxford in dark blue and Cambridge in light blue.
