Bradley Wiggins hinted that he may not ride the Tour de France again after injury and illness left him unable to defend last year's title.

"For me it was always about winning the Tour," the Briton told the Guardian website (

"I've done that.

"If I'm honest I don't think I'm prepared to make those sacrifices again that I made last year, with my family and so on. I've achieved what I've achieved. I'm incredibly happy with that."

Wiggins accepted that Sky team mate Chris Froome, a favourite to win in his absence this year, could be the team's Tour leader for some time to come.

"Chris has really stepped up, he's delivered now and he looks like he's really going to be there for a few years to win a few Tours maybe," said the four times Olympic champion.

"There has been a natural selection this year through Chris's performances and my performances that he warrants being the team leader; and if he wins the Tour, that continues through to next year. I can live with that."
