Tom Dean has won his second gold medal of the Tokyo Olympics as part of Great Britain's 4 x 200 metres freestyle relay team on Wednesday, day five.
Dean, James Guy, Matthew Richards, and Duncan Scott finished 3.23 seconds clear of the Russian Olympic Committee with a time of 6:58.58 -- just 0.03 seconds shy of the world record set by the United States in 2009. Australia came third to claim bronze.
"It was so close to the world record in the end, if anything, I'm a bit gutted," Scott said.
The victory marked the first time since 1908 that Britain had won three swimming gold medals at one Games, with Adam Peaty taking gold in the 100m breaststroke on Monday and Dean in the men's 200m freestyle on Tuesday, with Scott claiming silver.
Dean added: "I can't even put it into words, I couldn't yesterday and I don't think I can today."
"As a kid, winning an Olympic gold medal was my absolute dream and to do it after 25 years is pretty emotional," Guy said. "With these lads here, we're the best freestylers in the world -- my teammate [Tom Dean] and Duncan Scott getting first and second, it's just amazing how things progress.
"Michael Phelps and Ryan Lochte won in Rio, now we're the Olympic champions and that's a dream come true."
The U.S. team finished fourth -- the first time they have not won a medal in this event, aside from the boycotted Moscow Olympics.
In dressage, Charlotte Dujardin became the most-decorated British female Olympian after she won bronze in the individual event on Wednesday. The medal was her second of the games, winning bronze in the team event on Tuesday.
Dujardin now has six Olympic medals in total, including three golds at London 2012 and Rio 2016.
Team GB also took silver in the men's quadruple skulls, their first medal in that rowing category. Harry Leask, Angus Groom, Tom Barras and Jack Beaumont finished second behind the Netherlands and held off a late charge from Australia and Poland.
"It was wild out there. The conditions are rough, with a tailwind but it's what we're used to back at home so we've trained in this so many times, it did not shake us," Beaumont said.
"We decided that, as we were in lane one with an outside chance of a medal, we were going to take it to them and we really did it.
"I am so happy. It's the first Olympic medal for our boat class in this country and we're standing on the shoulders on loads of teammates before us. They helped us get here and it's another step on our way to getting the gold.
"British men's sculling can win medals now -- we're not in the background, we can do it."
Elsewhere, Sir Andy Murray's hopes of a fourth Olympic medal came to an end as he and his partner Joe Salisbury lost in a champions tiebreak to Marin Cilic and Ivan Dodig at the quarterfinal stage of the men's doubles.
Three-time Grand Slam winner Murray won gold in the men's singles at London 2012 and Rio 2016, and also won silver in the mixed doubles at London, but his charge for a fourth medal came to an end as they lost 4-6, 7-6 (2), [10-7].
Murray had planned to contest in the men's singles at Tokyo but withdrew before the tournament started due to a quad injury, as he prioritised the men's doubles.
"I don't know if I'll get the opportunity to play again," Murray said. "I've loved every minute of playing in the Olympics. I wished today could have gone differently.
"I had another chance with Joe to win a medal, we were so close, and that's what's disappointing. I would like to have done some stuff differently in the match to try to help out more. Very disappointed."
I feel crushed after todays loss 😞💔 sport can be brutal.— Andy Murray (@andy_murray) July 28, 2021
Thanks so much @joesalisbury92 for the opportunity to play. You were brilliant. I wish it could have gone a little better but shit happens. And if this is the end of my @olympics journey i want to say a huge thanks to
Later in the day, there was more tennis disappointment as Liam Broady was knocked out of the men's singles by Jeremy Chardy 7-6, 4-6, 6-1.
There was also not much joy for the men's coxless four as Team GB's dominance in that category came to an end on Wednesday, with the team nearly crashing at the end of the race.
Britain have won gold in the men's four in the last five Olympics but their race on Wednesday ended in somewhat embarrassing style with the boat being steered off course and nearly crashing into their Italian rivals.
The four were making their Olympics debut but Ollie Cook was left devastated and took responsibility for the error at the end. "I'm responsible for the steering. I screwed up," Cook told BBC Sport.
"I forgot the steering a little bit and that cost us a medal. To the lads, I'm sorry. I didn't steer us the best line at the end."
Team GB will still hope for further glory on the water and two-time Olympics gold medal winner Helen Glover and Polly Swann are into the final of the women's pair after finishing second in the semifinals behind Greece.
World middleweight boxing champion Lauren Price dominated her first bout at the Games, and said she was "massively" inspired by Britain's performance in taekwondo, a sport in which she has also competed.
A favourite to take the Olympic gold, the Welsh southpaw was effective with a flurry of shots to Mongolian Myagmarjargal Munkhbat, getting a solid left cross to her opponent's head in the first round.
Price looked energised and pleased after her win by unanimous vote, flashing a smile and sparring for the cameras as she left the arena.
"It's been annoying watching everyone box. I'm just glad to get out there," she said. "Obviously gold is the main focus, but I'm not going to think too far ahead of myself and just enjoy it."
Meanwhile, featherweight boxer Karriss Artingstall is guaranteed at least a bronze medal after winning her quarterfinal against Australia's Skye Nicolson.
Team GB's women's hockey won their second game on the bounce, beating India 4-1.
Following an early goal by playmaker Hannah Martin, the Indian squad pulled level with their opponents before falling behind in the 19th minute when Martin bagged her second.
The British team ran out comfortable winners in the end, scoring twice more in the second half.
"Momentum's key," Martin said. "As a squad, we are hoping to take this momentum forward into the Dutch game tomorrow."
Meanwhile, Argentina edged past Great Britain in the men's rugby sevens bronze medal match thanks to a 17-12 victory.
Great Britain were without their injured captain Tom Mitchell for the bronze match, and he saw his team take a 5-0 lead through Ben Harris, only for Argentina to strike twice before half time through Lautaro Bazan Valez and Marcos Moneta.
But Great Britain started the second half well and scored through Ollie Lindsay-Hague to draw the game level only for Ignacio Mendy to cross for a breakaway try to give Argentina the five-point lead.
Team GB tried to keep pressure on Argentina in the final minute, but Britain's ill-discipline let them down and Argentina cleared the ball into the empty stands to take bronze.
"Deflated, it hurts. There's not many words to sum it up, it really hurts," on-field captain Dan Bibby said.
"I am beyond proud of the boys of being here and giving everything to each other and to GB and all our friends and family at home.
"That is bigger than any medal -- I would trade all the medals in the world for the friendships I have here."
Elsewhere, in the men's time trial, Britain's Geraint Thomas finished 12th in a time of 57:46.61, four days after crashing in the men's road race on Saturday.
His teammate Tao Geoghegan Hart, who also crashed on Saturday, finished 29th and Anna Shackley finished 18th in the women's race.
