The
Celtic Challenge is a cross-border women's rugby union competition that will be held annually, launched in 2023. Designed to develop players for the Celtic nations of Ireland, Scotland and Wales, the inaugural pilot edition featured a double round robin between three teams, one from each participating union. From 2024 the competition will involve six teams, two from each participating union. Beginning with the 2024â25 season, the competition will maintain its six-team setup, transitioning into a full home-and-away round-robin format. The winners will be determined by standings at the end of the season.
