The most prominent sports are those classified as the "
Royal-Thomian". These sports take precedence because of the importance given to the clash between S. Thomas'
oldest rival, the
Royal College, Colombo. A cricket match between these colleges takes place in the first term of Lent every year. As the rains begin in Michaelmas Term, the rugby season has kicked off and the main encounter is the Royal-Thomian Rugby match. As the year ends with the term of Yuletide, the highlights are the
Royal Thomian Regatta and the Boat Race for the oarsmen of the two Colleges and simultaneously the two leg Water Polo matches for the
R.L. Hayman trophy.
Royal-Thomian Cricket Match The Royal-Thomian is the annual cricket match between
Royal College, Colombo, and S. Thomas' College, Mt Lavinia. It is the second longest uninterrupted cricket match series in the world and the first and oldest in Sri Lanka, even older than the Ashes cricket series, having been played for more than 140 years continuously. The original match was played between the
Colombo Academy and
S. Thomas' College, Mutwal, in 1879, with schoolmasters participating as well as schoolboys. From 1880 onwards, only schoolboys were allowed to play in the match. The match is played for the
D.S. Senanayake Memorial Shield, which was first presented in 1928. From 1979 matches were played for 3 days except in 1985 which was a 2-day match. A limited overs match (50 overs) was introduced in 1975 and is played for the Mustangs Trophy.
Royal-Thomian Rowing Regatta The Royal-Thomian Regatta (or Boat Race) is the annual rowing encounter between the Royal College and S. Thomas' College rowing crews. Having begun in 1962 'the Regatta' is the third oldest
sporting encounter between Royal College and S. Thomas' College, after the
Battle of the Blues Cricket Match and the Royal-Thomian Rugby Match. As of now, the event consists of eight school-boy races which carry points and three exhibition races that carry no points. The most important event which is 'The Boat Race' carries twelve points. The races are rowed over a distance of and take place on the
Beira Lake in Colombo. The regatta takes place in the Michaelmus term of S. Thomas' College, usually in the month of October and is traditionally held on the last Saturday of the month at the Colombo Rowing Club. The Royal Thomian Regatta is the oldest inter-mural rowing regatta in Sri Lanka.
Royal-Thomian Tennis Match The Royal Thomian Tennis is the annual tennis tournament between Royal College and S. Thomas' College, Mount Lavinia. The victor is awarded the E. F. C. Pereira memorial trophy.
Royal-Thomian Water Polo Matches The Dr.
R.L. Hayman Trophy is awarded to the winner of the annual two leg Water Polo fixture between Royal College, Colombo, and S. Thomas' College, Mt Lavinia. While Water Polo matches between the two schools have been held on and off through the annals of the two schools shared histories, the matches were made a permanent fixture as part of the two schools sporting calendars in 1992 as the Dr.
R. L. Hayman Trophy Royal-Thomian Water Polo Matches. The event was initially played in home and away swimming pools. However, while it is still a two leg event, for the past several years it has been held at the
Sugathadasa Stadium Swimming Pool allowing for much larger participation and making it the best patronised Water Polo matches in Sri Lanka and Asia. As of 2019 the tally stands at S.Thomas' winning 16, Royal winning 8 and 3 matches drawn. ==Wardens==
