Laura Kenny became the first British woman to win gold at three Olympic Games since she and Katie Archibald Madison were selected champions in Tokyo.
Kenny, 29, became GB’s most decorated female athlete with her fifth gold and sixth Olympic medal overall.
“I have never wanted to win a medal so far in my life,” said Kenny, the most successful female Olympic cyclist.
Jack Carlin won Team Sprint bronze for his second medal at the Games and Team GB’s fifth medal on the track.
He won Team Sprint Silver with Jason Kenny and Ryan Owens earlier this week, while Laura Kenny and Archibald won Team Pursuit Silver.
Their Madison gold on Friday after Matt Walls ’victory in the men’s omnium the previous day.
Women’s Madison was added to the Olympic program for the first time in Tokyo 2020.
“I texted [husband] Jason and felt that today was the end of my Olympics,” Kenny said.
Archibald added: “I dream about this conversation – I never wanted anything like this, I was never scared but we were very clinical with our approach.
“We changed the coach last year for this event. We are trying to promote between events and it has been very satisfying to come.”
Kenny and Archibald deliver a masterclass
Archibald won gold at the 2018 World Championships in Madison, and she and Kenny teamed up for European Silver at next year’s event.
Their performance in Tokyo won them a master class in Madison Racing, 120 laps, and three opening sprints in the 30 km race.
In total, they won 10 of the 12 sprints on offer, and Denmark and the Russian Olympic Committee scored 20 points respectively, winning silver and bronze.
But Kenny and Archibald dominated as they ended up with twice as many dance points, while Amalie Didierixen and Julie Leth finished their race with 35 points, while ROC had just 26 points.
Dutch world champions Amy Peters and Kirsten had to settle for fourth after being caught in a wild crash.
Kenny and Archibald coach Monica Greenwood – who took over as coach for the endurance team in December – revealed that for their win, they are training against GB’s men’s under-23 squad to perfect the Madison plan.
Kenny Gold, who welcomed son Albie in August 2017, is the first person to become her mother.
“I’ve been saying all week, please don’t ask me about Albie – I did not miss him so much,” she told BBC Sport.
“But I can not do without these girls. With Katie it feels like I’m racing with a sister – I’m so thankful she’s here and supporting her. I can not do without her.”
She later said: “When I got pregnant, I woke up two months after I got pregnant and said to Jason, ‘I can not do this, I can not continue cycling, there is no way.’ And here we are. “
