The Welsh state school won through against the likes of perennial powers Millfield, Bryanston and Wellington College, who they beat in the semis.

Whitchurch trailed 14-0 at half-time in the final against QEGS Wakefield, but produced a fine comeback to win 19-14.

Elliot Jones winged in for two tries before Tom Rowlands, who had converted both, added a last-minute winning try.

Whitchurch Physical Education teacher Tim Henson, who along with colleague Ian McIntyre coaches the under-16 side, praised the character of his players.

"There is a lot of talent in the school and we've all put a lot of work in, but its mainly down to the kids' willingness and desire to play," Henson said.

"We went into half-time against Wakefield 14-0 down, but we told the boys to get up in their faces, get the ball and keep the ball.

"That second half was the best seven minutes of Sevens I've seen, we just didn't give them the ball.

"To beat some of the most prestigious public schools in Britain and win that final was absolutely fantastic.

"It is a huge achievement, especially as this time of the year our main priority is 15-a-side rugby.

"We're training for a Welsh Cup semi-final game on Monday, so for the boys to adapt to the Sevens game is fantastic."

While Whitchurch's rugby sides - in both codes, union and league - regularly feature in Welsh and British finals, the school has a record of sporting excellence beyond the oval ball.
