Cardiff and Merthyr's showdown in the WRU National Cup final is the headline act of a week of community rugby events at Principality Stadium.
The Ironmen will look to defend their crown in an inter-regional final on Sunday, April 28, but must break past a strong Blue and Blacks side, who will be looking to win the trophy for the eighth time in their history.
Both sides currently occupy the top two places in the Principality Stadium, with Dale McIntosh's side edging ahead after a comprehensive victory over struggling Bargoed on Saturday.
Cardiff and Merthyr go toe-to-toe on the day after Judgement Day, and more than 100 clubs across the country set to emulate their heroes and play on the hallowed turf. There will be plenty of representation from Wales' Capital Region throughout the week.
Another club from the region to earn their place at the home of Welsh rugby on Sunday is Brecon RFC, who will take on Bonymaen in the National Plate final earlier in the day.
Brecon head coach, and former Cardiff Blues, Wales and Lions number eight, Andy Powell, said: “It is huge to be playing in that stadium, it’s a mad feeling. I’ve been there myself, but it’s not about me, it’s about these boys.
“They’ve worked hard all season and we targeted getting to the final. I’m simply over the moon, it’s the best feeling in the world and I will cherish this moment forever. This couldn’t have happened to a better bunch of lads.”
Monday will kick off with a Walking Rugby Festival, which includes representatives from Cambrian, Cardiff, Pontyclun and Pontypridd, before Cardiff Chiefs' mixed ability side and the Cardiff Lions gay rugby team take to the Principality Stadium pitch.
Christ the King Cardiff, YGGG Llantrisant, Ysgol Glantaf and Whitchurch all feature in Tuesday's WSRU finals, while nine Cardiff Blues players have been selected in the Wales Women Emerging squad to take on England U18 Talent Development Group in the evening.
Wednesday sees Aberdare Community School compete in the WSRU under-18 male cup final, with Cynon Valley Schools and Cardiff Schools playing their part in the DC Thomas and Dewar Shield finals respectively on the Thursday.
Both Cardiff Quins and Cardiff Met are in action on Saturday, May 4, as they take on Penallta and Morriston in the Youth Plate and Cup finals.
