Britain's most successful Olympian announces retirement

Track cycling great Jason Kenny has announced his retirement, with Britain's most successful Olympic competitor moving into coaching.

The 33-year-old revealed on Thursday that he has started work as British Cycling's men's podium sprint coach and is in charge of several riders who were his team-mates until recently.

Kenny's seventh Olympic gold medal came in the keirin at the Tokyo Games last August, 13 years after his first in Beijing.

He had intended to compete at the 2024 Paris Olympics but Kenny said the chance to coach the British squad was too good an opportunity to turn down.

"It wasn't an easy decision," said Kenny, who is now officially 'Sir Jason' after being knighted in Britain's New Year Honours list.

"I genuinely wanted to carry on to Paris, but I creak quite a lot these days and I always knew I wanted to go into coaching off the back of it, and this opportunity came along.

"I am a little bit sad to be honest because all I've known is riding and competing, but I'm quite excited to get stuck into the job."

He added: "This opportunity might not come here again. If they got a good coach they could be in the role for potentially 10 years, so I thought I'd go for it now... I think if I hadn't got the job I would have carried on (racing) in all likelihood."

Kenny previously quit after winning team sprint, individual sprint and keirin golds at the 2016 Rio Olympics, but reversed his decision a year later.

'It was really special'

He insisted he was getting off the bike for good this time.

"Since I came back into it I've really enjoyed it again. So this time I'm absolutely loving it, so now I'm going to quit!"

Kenny is one half of one of sport's most successful couples, with wife Laura also an outstanding cyclist.
