 Teams from the US and Canada take part, and British teams used to compete before the British GAA formed their own competition.The CYC was developed by the GAA's Overseas Development Committee under Gene Duffy, and is managed directly from Croke Park by the CYC Steering Committee that consists of officials at Croke Park as well as members of the GAA in North America.At local level, the event is planned by the CYC Hosting Committee whose membership changes from year to year as the tournament moves from city to city.
