Geraint Thomas admits he has thought about when he might retire from professional cycling, but thinks he could compete for another decade.

The 29-year-old Welshman is a double Olympic track champion, taking team pursuit gold in 2008 and 2012.

He is also the reigning Commonwealth Games road race champion and finished 15th in this year's Tour de France.

"I could keep riding until I'm 40 - it's a lot more mental than it is physical," the Team Sky rider said.

"I've been a pro for nine years... I'm starting to think now the end isn't... well it is far away but it's kind of not either.

"You look at Chris Hoy who was 36 when he won a gold medal in London and everyone says you get slower as you get older. He didn't.

"It is weird now, especially when I hit 30 next year I'll probably be like 'oh no!'."

Thomas has won widespread praise in his domestique role helping Chris Froome win the 2015 Tour de France.

But Team Sky principal Sir Dave Brailsford has tipped Thomas as a future leader at a Grand Tour, either at the Giro d'Italia, Vuelta a Espana or Tour de France.

*Thomas was speaking on a special 91Èȱ¬ Radio Wales Sport programme 'At 91Èȱ¬ with Geraint Thomas', which is available to listen again via iPlayer and as a podcast.
