Team GB will play New Zealand in the semi-final of the women's rugby 7s at the Deodoro stadium after a comprehensive 26-7 win over Fiji.
Two tries from Abbie Brown - the first almost immediately from the opening kick-off - gave the British team the momentum to progress, with further tries from Alice Richardson and Joanne Watmore.
Following a 22-0 victory over Canada in the final pool game, Great Britain conceded their first try of the tournament against Fiji, but recovered to ease to victory.
“I’m really proud of the team. They showed great composure under the utmost pressure, and great execution to realise their potential on the biggest stage," said head coach Simon Middleton.
“I was equally impressed with the girls with how they came back [from conceding the try]. We hadn’t conceded a try in the competition. I said to Emily Scarratt before we went out that we might concede in this, but we’re going to score 30 points, so don’t panic."
Panic they did not, with Richardson collecting a kick-and-chase before handing off a pair of defenders to restore GB's lead. Watmore added a third first half score before Brown sealed the game with the only score of the second half.
New Zealand beat the USA 5-0 to secure their place against GB in Monday's semi-final and two-try hero Brown hopes to keep building the team's momentum.
“We keep building every game, focussing on ourselves and taking each game as it comes. That’s what you’ve got to do in sevens. After Canada we only thought about Fiji. We didn’t even think about tomorrow because there’s no point.
“[The final four] is where we’ve aimed to be and we’re aiming for that final, but we’ve got to take one game at a time."
