DOMINANT RGC 1404 made an emphatic start to life in the SWALEC League One East after proving too strong for Gilfach.
Five tries saw RGC off to a 42-19 win away to their Caerphilly hosts, and head coach Chris Horsman said the club’s debut win was “a fantastic day for North Wales.”
He told the Welsh Rugby Union: "It's a fantastic day for North Wales and I feel very humbled to be the head coach.
"It's not just me though, so many people are involved in it and I feel humbled really to be lucky enough to head it up."
"This is a step up of about four or five leagues for our boys who have been playing in Division One North and Division Two North and to come into Division One of the national leagues is a huge step.
"There were a few nerves but with a young side and coming to a difficult place we'd have taken 42 points this morning.
Llandudno fly-half Rhodri Carlton-Jones added the extras as Mike Jones and Harri Evans put RGC 14-0 ahead.
A couple of Filfach penalties pegged back the North Walians, who restored their superiority when winger Richard Hopkins went over, opening up an eight point gap at the break following a try for the hosts.
Flanker Tom Parry scored the first of two for the afternoon early in the second, and though RGC had two men yellow carded, controlled proceedings for what became a comfortable win.
Parry added his second late on, with Carlton-Jones kicking the conversion as well as two late penalties to round off a superb debut.
The win was follows up by a tough draw for 1404 in the Welsh Cup, having drawn tough South Wales squad Swansea in their first knock-out match.
