An extraordinary six days in the velodrome ended with Laura Trott becoming Britain's most success female Olympian of all time, by winning her fourth gold medal in the omnium. Just a few hours later, she watched as her future husband Jason Kenny equalled Sir Chris Hoy's record with the sixth gold of his career – and his third of the Games – in the keirin final.
Laura, 24, was in tears as Jason, 28, pedalled his victory lap, his arms raised up in the air, before the couple embraced and kissed as the crowd cheered.
"The best thing about it is that we get to come away together and race together," said Jason after his race. "Not many couples in the Olympic village can enjoy their success together. So that's really special and I feel really lucky about that."
Appearing in his first Games, 20-year-old Nile Wilson made a name for himself as he became the first Briton to secure an Olympic medal in the horizontal bar.
The gymnast from Leeds won bronze - Team GB's seventh gymnastics medal received in Brazil.

Nile's success came less than an hour after his teammate Amy Tinkler won bronze in the women's floor.
Sixteen-year-old Amy - Team GB's youngest athlete - broke down in tears and hugged her coach as she was ranked third in the gymnastics event.

British diver Jack Laugher is coming home with two medals.
Just six days after winning gold with his synchronised diving partner Chris Mears, 21-year-old Jack was presented with a silver in the 3m springboard final.
"Second place at the Olympic Games!! Can't believe it!!! Baby we did it!" Jack wrote, proudly showing off his newest medal in a Twitter photo.
The 29-year-old Scot managed to overcome Argentina's Martin del Potro in four thrilling sets to defend his London 2012 title and secure his place in the history books.
"To defend the singles title… I think Venus and Serena (Williams) have won about four each but haven't defended a singles title before," Andy told the BBC after the match. "It's obviously not an easy thing to do. I had to fight unbelievably hard tonight to get it."
History was also made by Max Whitlock, who became the first ever Team GB gymnast to win Olympic gold medals after stunning victories in both the men's floor and the pommel horse.
He was joined on the podium by team mate Louis Smith, who took silver in the pommel for his third consecutive Olympic medal in the event.
A dramatic fall in the middle of the race drew an audible gasp from the crowd, and there was added drama when Paul Kipngetich Tanui made a dash for the finish line in the final lap. But he couldn't hold off Mo's famous kick sprint and it was the British star who took the gold in Rio.
Gold medal winner Ryan Lochte was among a small group of athletes held up at gunpoint after a party in Rio.
The 32-year-old, who won gold in the 4x200m freestyle relay, and three other American swimmers were out celebrating when they were robbed at gunpoint early on Sunday by thieves posing as police officers, who stopped their taxi and took money and personal belongings.
Ryan confirmed the incident, telling NBC that one of the robbers had put a gun to his forehead before taking his wallet. Thankfully no one was injured in the incident.

Usain's victory means he remains on target to leave Brazil with a third successive Olympic treble, having won the 100m, 200m and 4x100m relay titles in 2008 and 2012.
Tom Daley and Dan Goodfellow helped boost Team GB's medal tally on day three of Rio 2016 by claiming bronze in the men's 10-metre synchro event.

Even before she stepped up to the vault in Rio, Oksana Chusovitina had made history. The 41-year-old is currently competing in her seventh Olympic Games, and is the oldest woman to have ever done so.
Oksana, who is representing Uzbekistan, is mother to a 17-year-old son Alisher; to put it into perspective, one of the gymnasts competing in her rotation was born just two months before Alisher.
But Oksana isn't just there to take part – she's there to win. She earned a score of 14.999 on the vault at the weekend, successfully qualifying for the vault finals.

"It's surreal to get Team GB's first gold," said Adam, who finished more than 1.5 seconds clear of his nearest rival. "I came out tonight and took the first 50 easy and came back with everything I have got.
"I did it for my country and that means so much to me."
British Commonwealth judo champion Ashley McKenzie couldn't hide his emotion after making an early Olympic exit in Rio.

Shane Tusup, the husband and coach of Hungarian swimmer Katinka Hosszu, made headlines around the world thanks to his euphoric celebration of his wife’s 400m individual medley win.
Katinka 27, who calls herself the Iron Lady, won gold in the final and broke the previous world record set by China's Ye Shiwen at London 2012 – and images and footage of her ecstatic husband cheering and fist pumping pool side soon went viral.
That moment, along with a recent New York Times profile on the couple, has put their relationship in the spotlight however, and questions have been raised about Shane's behaviour.
An NBC announcer alluded to the rumours during Sunday’s broadcast, saying: "The influence he's had on her… it can be very, very harsh. In fact, it's been a little disturbing to other swimmers who've observed it. And Hosszu admits that."
Jessica Hardy, an Olympic medallist who used to train with Katinka, was one such swimmer. "I've seen a lot of inappropriate and not-OK behaviour in Shane," she has said. "I've seen coaches exhibit that kind of behaviour in training, but this is another level, it's scary."

It's not the first time an injury has shattered Samir's Olympic dreams. He was forced to pull out of the 2012 Games after fracturing his leg in three places during the European Championships.

The Royal Dutch Cycling Federation (KNWU) later confirmed that Annemiek, who lay motionless on the course after the crash, had suffered concussion and three fractures to her spine.
