Britain's Kenny completes his golden hat-trick

Jason Kenny was "untouchable" at the Rio Olympics, according to the man whose record the sprint sensation equaled on Tuesday.

Kenny, 28, won his sixth Games gold medal in claiming the keirin championship at the Rio velodrome, drawing level with fellow track cycling great Chris Hoy as Britain's most successful Olympian of all time.

He also matched Hoy's remarkable achievement from Beijing eight years ago of taking three gold medals at one Games - in the sprint, team sprint and keirin.

It brought with it gushing praise from the man he might yet surpass in Tokyo four years from now.

"Jason has been untouchable this week, he has been on a different level," said Hoy. "He has dealt with extreme pressure - he is a true champion."

The sprint stars' records are identical: six gold and one silver medal.

Hoy, who was commentating for British television in Rio, handed Kenny his one defeat in an Olympics, beating his then 20-year-old teammate in the sprint in 2008.

But four years ago in London, Kenny took Hoy's place as the team's top sprinter.

"When he first came on board at Beijing we knew we had a talent, but we didn't know what a special talent he was," Hoy told the BBC.

"His character is just fantastic. This is a really special moment - a phenomenal performance tonight and all week."

It was a golden double on Tuesday for Kenny and fiancee Laura Trott, who won the women's omnium.

Trott also won the team pursuit in Rio, accomplishing the same double she managed as a 20-year-old in London four years ago. She is the most successful British female Olympian.

The couple now has 10 Olympic titles between them.

"It's amazing, I'm really happy for Laura, I know how hard she works and how much she wants to win," said Kenny.

"I'm really proud of her ... but I'd be proud of her even if she didn't win."

An emotional Trott burst into tears as Kenny won his sixth gold.

"I can't believe I've done that," she said of her fourth gold medal.

Things will be getting even better for the star couple later this year, although Kenny is not sure whether he will carry on to another Olympics.

"I've got a bit to do in the next few months ... get married and then reflect on it," he said.

While Trott was totally dominant in the omnium, Kenny's keirin victory was controversial, as he and bronze medalist Azizulhasni Awang of Malaysia appeared to jump the gun in the final.

A false start was called but neither was disqualified as officials couldn't decide which one had infringed first.

On the restart, German world champion Joachim Eilers also false started, but having let off the other two, officials did likewise with him.

"Ultimately it was the right decision, it was ridiculously tight and it's a bit vague, that kind of rule," said Kenny. "Someone was a bit trigger happy today."

British head coach Iain Dyer even produced video material taken by his backroom staff to show officials the call wasn't obvious.

His video evidence also spared Eilers on the second false start.

"I was well placed and I thought it was a massive call to make for a guy to make with the naked eye," said Dyer.

"I think they dealt with the doubt well. There was clearly doubt, everybody wanted the best and fairest possible outcome and I think they did achieve that."
