The competition is generally considered the most prestigious in Ireland, due in part to the additional media attention provided by its sponsor, but also the status of some of the former winners, and the US tour which forms part of the prize. Running between November and February, it operates on a knockout basis, with the initial entrants (usually between 150 and 170 teams) being whittled down over successive rounds, culminating in a Grand Final with four teams and four individuals competing for team honours (The Demosthenes Trophy) and an individual prize (The Christina Murphy Memorial Trophy).
