Cardiff Blues and Wales centre Cory Allen and record try scorer Luke Morgan joined Treharne in beating fellow Olympians France 33-17 in the final, while James Davies and Sam Cross were in the GB Lions squad that beat Germany 31-19 to lift the Plate.
The two groups will now have one final chance to impress in the final round of the Rugby Europe Sevens Series this weekend in Poland. The coaches will then decide which 12 players will travel to Rio to compete in the Olympics for Team GB, with the squad announcement scheduled for Tuesday, 19 July.
“It has been a really tough six weeks in camp and all 27 of the boys have really been pushing each other,” said Treharne, who was named as the Mitsubishi Motors Player of the Tournament.
“Much of the play this weekend shows that the hard work in training has been paying off and the Lions winning the plate is also an excellent effort. Hopefully, we have all given the coaches plenty to think about.”
The GB Royals came from 12-0 down to beat fellow Olympians France 33-17 in the cup final while the GB Lions lifted the plate with a 31-19 victory over Germany. It was a double boost that has given Team GB head coach Simon Amor and his assistant Gareth Williams plenty to ponder ahead of their Olympic selection.
“I’m delighted with the courage the guys have shown, they came together as a group only six weeks ago and they have been absolutely outstanding. They have fought and fought and fought not just across this weekend but throughout the whole programme,” said Amor
“I am proud of them and I am proud of the staff that have come together and made it all happen. We have some absolutely unbelievable players, there is so much talent to pick from and now we need to work out which combinations work the best.
“They have given us some massive selection headaches and that is exactly the place we wanted to be in, Gareth Williams and I have some really tough decisions to make.”
Treharne’s side found themselves 12-0 down in the final, but a moment of class from Harlequisn wing Ollie Lindsay-Hague saw him chip over the defensive line and gather to touch down under the post, reducing the deficit to 12-7.
France responded through Pierre-Gilles Lakafia, who scored in the corner after a missed tackle, and France looked set to go into the break with a 17-7 advantage. But with just two seconds left of the opening period, Alex Davis brushed off two tacklers to touchdown down and make it 17-14 at the interval.
The Royals had beaten France 17-10 in their Pool match and went on to dominate the second half in front of a partisan and noisy home crowd. They scored 19 unanswered points with James Rodwell leading the charge with a galloping run through the French midfield to score the first of three tries.
Treharne converted four of the five tries in the final and it was his kick that settled a tough semi-final against Russia. He added the extras to the first of two tries from James Farndale to give the Royals a 7-5 interval lead before they went on to win 12-10.
The GB Lions dominated their Pool, beating Belgium 31-5, Italy 31-0 and Germany 41-0. Scarlets flanker James Davies scored twice in the win over the Belgians, but he wasn’t able to keep his side on course for an all-British final when the Lions met Russia in the quarter-finals.
After a tense first-half that ended scoreless, Dan Norton’s quick feet eventually put the Lions five points ahead in the second period. But German Davydov’s try and subsequent conversion handed the Russians a 7-5 win.
That meant Lions went into the Plate, where they bounced back in style in the semi-final – dispatching Georgia by a 22-7 scoreline. They then put in an equally dominant display against Germany in the final as they turned a 12-7 first-half lead into a 31-19 winning margin.
