Blundell's must be one of the oldest fives playing schools in the country, with records going back to 1625. Fives is still played throughout the year, although the majority of school fixtures take place during the Easter term. The school has six Rugby Fives courts which, unlike Eton and Winchester Fives courts, have no buttressing.
Sherborne, King’s Bruton and Clifton College provide the bulk of local opposition although the school team has been known to travel as far afield as Radley, Bloxham and Rossall for tournaments. 2003 saw the first Blundell's Fives Tour to Scotland. School teams enter the National and West of England Tournaments each year. The school also hosts touring Club teams such as Deep West and The Jesters and a number of Old Boys regularly return to use the courts.
All Blundellians, regardless of experience, have access to the Fives courts, which underwent extensive renovations a few years ago. Both gloves and balls are provided by the master in charge and stocked in the school shop.
