Rugby’s Celtic Challenge debuted last season, with the aim of providing a platform for players to develop in a high performance environment, but what’s changed about it this year, and what does that mean for the competition and its players?
What’s the new format of the Celtic Challenge?
The competition retains its core format of a cross border face off between the IRFU (Ireland), Scottish Rugby and the WRU (Wales), although this time it will take palace over an 11 week period. 
There’s also a new look in terms of the amount of teams and the structure of the tournament.
This time, six teams, two from each nation, will battle it out across five rounds.
Subsequently, and as a result of the standings, the playoffs will consist of three rounds, and will ultimately see one team crowned the overall winner.

Last time out the Irish players competed on behalf of the Combined Provinces XV, but this time around there’s been a slight shake up, given the addition of more team slots.
Irish players will play under two banners, Connacht and Munster as the Clovers, and Leinster and Ulster as the Wolfhounds.
Scotland’s teams are listed as Edinburgh Rugby and Glasgow Warriors, while Wales opted for Brython Thunder and Gwalia Lightning.
Interestingly, it has been stated by the IRFU that “in order to provide quality game time and positional cover, there will also be some crossover with the provincial players.”
Show a real lack of planning, communication, & consideration to the many many volunteers that put time & effort into their teams
It feels like the IRFU are stumbling their way to professional provinces and a league for them to play in but not thinking about what it's built on

Gillian McDarby, IRFU Head of Women’s Performance and Pathways, commented on the fresh format for the competition, mentioning that its “an integral tournament for the development of women’s rugby players in Ireland.”
“It will play a significant role in the player pathway moving forward,” she says.
On the decision to move beyond one team per organisation was due to a “collective goal of the three unions to elevate the Celtic Challenge to the highest level of competition possible, ensuring that players are in the best position to compete in the Women’s 6N.”
