The Old Spierians club had been founded in the early years of the 20th century and joined the Scottish Rugby Union in 1911.

National league competitions were introduced in Scotland in season 1973–74 and Garnock had some initial success, being promoted to Division 3.

After only eight years, the clubhouse was condemned by the local council as being fundamentally unsound and the club had to resort to using Portakabins for changing facilities.

Success continued into the next decade, with the team gaining promotion to Premiership Division 3, being runners-up in the Shield in 2007[3] and winning the same competition in 2008.
