Centurions
GHA have a long tradition of recognising when players reach the milestone of achieving 100 caps for the 1st XV and it is considered the ultimate personal honour for any GHA player. At the annual Club Dinner & Awards Night all new centurions receive an engraved silver tankard in recognition of this great achievement and as a thank you for their long and dedicated service to the club.
