Great Britain's eventing team secured Olympic gold after an excellent performance in the showjumping at Tokyo 2020 on Monday.
Team GB were in gold-medal position going into the final stages of the competition following the dressage and cross country on Sunday.
Tom McEwen got off to a flying start with a clear round, with Laura Collett maintaining the strong position after finishing with four penalties.
Oliver Townend went out last and finished with just one fault to clinch the gold medal for Great Britain.
"I didn't know how much we had in hand so I put myself under a bit of pressure," said Townend.
"These two guys have made it very easy for me jumping such amazing rounds. Tom went in and nailed a clear round, Laura's horse had a spook but she gave him a brilliant ride as always.
"We're surrounded by classy horses and very classy people.
"It's unreal, it hasn't sunk in. We've got another round to jump so we'll focus on that but there'll be a big celebration -- and I don't think it'll be with a cup of tea and a biscuit."
McEwen also won silver in the individual competition after a second clean run in the final round of jumping. Townend and Collett finished fifth and ninth respectively.
Elsewhere, Emily Campbell became the first-ever British female to win an Olympic weightlifting medal after winning silver in the +87kg category.
The 27-year-old won European gold earlier this year and lifted 283kg to take second behind China's Li Wenwen, who recorded an Olympic record in her combined total.
"I'm actually speechless, for the first time ever," Campbell said.
"I just want to thank everyone who believed in me. You can achieve anything you want to, I picked up a barbell for the first time five years ago for the first time and now I'm an Olympic silver medallist."
Transgender athlete Laurel Hubbard did not finish the competition after failing to make her snatch weight.
Meanwhile, Great Britain's women's hockey team progressed to the semifinals after a dramatic penalty shootout win against Spain.
Team GB led 2-1 going into the final quarter of the match but a goal from Spain nine minutes before full time levelled the two sides.
In the shootout, GB goalkeeper Maddie Hinch stepped up to the plate and saved Spain's first three attempts. Goals for Britain from Hannah Martin and Sarah Jones meant Spain had to score to stay in the running.
But it proved too much for Spain, despite being awarded a retake in their fourth penalty, with Hinch making another save to secure GB's spot in the semifinal.
Team GB will face the Netherlands on Wednesday, in a repeat of the Rio 2016 final where Britain took gold.

In the first day of track cycling, Britain progressed to the next round of both the men's and women's team pursuit.
The women qualified in second behind Germany, who smashed the world record to take the top spot.
The British team, which includes four-time gold medallist Laura Kenny, were quicker than the world record they previously held but still a second behind Germany's new record time.
The men qualified fourth fastest, meaning they will face world champions Denmark on Tuesday.
At the Tokyo Aquatic Centre, Team GB's Rio 2016 silver medallist Jack Laugher qualified in sixth for the 3m springboard semifinal, with his teammate, James Heatly, qualifying ahead of him in fourth.
Elsewhere, 16-year-old twins Jennifer and Jessica Gadirova couldn't follow up their bronze medals in the team event, finishing sixth and seventh respectively in the gymnastics floor final.
