Wales fly-half Sam Costelow has joined the coaching staff of his boyhood club Pencoed RFC ahead of next season.
The 25-year-old, who won the latest of his 20 international caps during this year’s Six Nations, hails from the town and began his career there as a young boy before going all the way to Test rugby via the Ospreys academy, Leicester Tigers and the Scarlets. Now, he is taking on a new role with the club’s senior side, who play in the WRU National League Divison 2 West.
Costelow has joined Pencoed’s set-up as attack and skills coach and will assist head coach Sean Donovan in the role during the 2026/27 season.

Confirming the appointment in a statement, the club said the fly-half had been brought in to “ignite our attacking play with top‑level insight and creativity,” adding that the new coaching and management team offers “a blend of experience and fresh energy”.
As well as Donovan and Costelow, Pencoed’s coaching team includes backs coach Marc Davies, contact area coach Tom Geere and assistant forwards coach and former club captain Kieron Moore. Win free tickets to watch Fiji v Wales in Cardiff this summer.

In his new role, Costelow may well find himself in the position where he is coaching former Wales and British & Irish Lions star Gavin Henson, who is nearly 20 years his senior.
The two-time Grand Slam winner is another who has returned to his boyhood club, pulling his boots back on and representing the team over the past two seasons, five years on from his retirement from professional rugby.
After making a surprise return to the grassroots game, Henson has managed to roll back the years, with a trademark monster tackle leaving one of his amateur opponents flattened earlier this year.
It remains to be seen whether he will continue playing for another season, but if he does, the 44-year-old is set to work closely with Costelow, having been playing at fly-half for Pencoed over the course of the campaign.
Speaking to BBC Scrum V last year, the former centre admitted that he was “loving” being back playing with Pencoed, with his competitive streak not diminishing even away from the professional game.
“I’m 43 now, so a bit old, as my wife tells me,” he said. “But I’ve missed it, I’ve missed the physicality of it, and being in a team environment again and trying to win.
“I’m very competitive, I like trying to win, that’s the main thing. We have a good group of boys. We’re aiming for promotion, so hopefully it will be a good season and great for the club.”
“I’m playing 10,” he added. “I would like to play 12 but I am just not quite big enough yet. So I’ll still try to aim to get there but 10 at the moment.”
