Dame Laura Kenny, Britain's most successful female Olympic athlete, has announced her track cycling retirement just four months out from the Paris Olympics.

The 31-year-old has won five Olympic gold medals in her decorated career and had been expected to compete at the Paris Games, but she told the BBC it was time to stop.

Speaking to BBC Breakfast, Kenny said: "I always knew deep down I would know when was the right time. I have had an absolute blast but now is the time for me to hang that bike up."

Kenny and her husband, Sir Jason Kenny - Britain's most decorated Olympian - last year welcomed a second son to their family and she said spending time at home was proving more and more alluring to her.

"It's been in my head a little while, the sacrifices of leaving the children and your family at home is really quite big and it really is a big decision to make," she added.

"More and more, I was struggling to do that. More people asking me what races was I doing, what training camps was I going on - I didn't want to go ultimately and that's what it came down to.

"I knew the minute I was getting those feelings. Once I said to Jase, 'I don't think I want to ride a bike anymore', I started to feel relief."

Kenny won team pursuit and omnium gold at both the 2012 and 2016 Olympic Games and madison gold at the 2020 Olympics, where she also won a silver medal in the team pursuit.

She is a seven-time world champion and 14-time European champion, won two Commonwealth Games titles and was British National Road Race champion in 2014.

"Going on to win another gold medal, as much as I would love to do that, it wasn't giving me the energy I wanted anymore, it just wasn't," she added.
