BOLTON’S Olympic cycling hero, Jason Kenny, will have to dig out his old stabilisers – after his wife and fellow gold medallist Laura Trott revealed she is pregnant.

Britain's most successful female Olympian posted a photograph of two adult bikes and a child's bike on Instagram on Valentine’s Day, with the news later confirmed by the couple’s agent.

And bookies have already started taking bets at 50 to one that the Farnworth Flyer's first child will win an Olympic medal.

Jason and Laura’s agent, Luke Lloyd-Davies, said in a statement to Press Association Sport: "I can confirm that Laura Kenny is indeed pregnant and that she, Jason and their respective families are absolutely thrilled and delighted with the news.

"They very much appreciate all the kind wishes and messages of support that they have received already."

Responding to Laura’s Instagram post, Jason responded on Twitter with a joke, posting a picture of the pamphlet entitled ‘So You’ve Ruined Your Life’ handed to a pregnant Marge in The Simpsons.

Jason, 28, who turned on Bolton's Christmas lights last year alongside Laura, 24, tweeted: “I wondered why this leaflet came through the post.”

The news was made public after the couple's 12-week scan and greeted with messages of congratulations online.

The pair's relationship became public at the London 2012 Olympics, where they each won two gold medals in the velodrome and were pictured kissing at the beach volleyball competition at Horse Guards Parade.

At the time it was joked that British Cycling had embarked upon a breeding programme.

The couple were asked about the prospect of becoming parents at last August's Rio Olympics, when Jason won three golds to move level with Sir Chris Hoy on six golds as Britain's most successful Olympian.

Speaking in Rio, after two more golds took her Olympic tally to four, Laura, said: "We haven't exactly thought about it.

"I guess I am still quite young. I only put it out there because everybody kept going on about it.

"So I was just like: 'It could be the best omnium rider in the world, couldn't it? Bit of sprint, bit of endurance. You never know. 20-something years down the line, you never know."

With pregnancy having arrived significantly earlier, Laura will now take an enforced break from the bike, missing April's Track World Championships in Hong Kong.

Meanwhile, bookmakers William Hill are offering odds of 50 to one that the couple’s first-born will win an Olympic medal.

Spokesman for William Hill, Joe Crilly, said: “Laura Trott famously tweeted during the Olympics that any child they had would be blessed in the gene department, and given that we have previously offered 500/1 for Kai Rooney to play for England and 100/1 for Jaden Agassi to win a Grand Slam, we think she may be right.

“Despite the fact that the announcement was only made on Valentine’s Day, we have already been inundated with requests for the long term wager.”
