Marr RFC

Marr play their home games at Fullarton estate and has done since early 1970s. Until then it had used the school grounds since the club's formation in the 1940s. It was originally for the former pupils of Marr College, a secondary school in Troon, and there is still a close affiliation between the club and local high school. They play in the distinct colours of purple, gold and green. Over the last few years Marr has had a revival mainly due to the introduction of former Scotland 'A' cap Craig Redpath as head coach and latterly Former Ayr players Paul Burke and Stephen Adair as additional coaches.

Starting with the 2010–11 season, Marr began a run of four successive league title wins which promoted the club from the sixth to the second tier of Scottish club rugby for the 2014–15 season. They were promoted in the 2016–17 season and for the 2017–18 season they will play in the Scottish Premiership.

The side topped the Scottish Premiership in season 2019–20, but the SRU declared the season null and void as it ended prematurely when the coronavirus pandemic broke out.
