The game is very similar to the male form of Gaelic football, where two teams of 15 players kick or hand-pass a round ball towards goals at either end of a grass pitch. There are two main competitions in this sport; the National League which is staged during the winter-spring months and is used as a warm-up to the All-Ireland Championship which is played during the summer. The All-Ireland Final is played on the last Sunday in September or the first Sunday in October in Croke Park, Dublin, where the winners receive the Brendan Martin Cup. The National League and Championship are organised by the Ladies' Gaelic Football Association.
