British Cycling technical director Shane Sutton has admitted that he is unsure whether Sir Bradley Wiggins will compete at the 2016 Olympics in Rio.

Wiggins added to his long list of achievements by breaking the hour record at the weekend, but Sutton believes that the 35-year-old could abandon his bid for success next year.

Sutton told Sky Sports News: "He's got a great coach in Heiko Salzwedel with him, and Tim Kerrison and the whole team have done a great job getting him to here, but can we get him to Rio now?

"I'm not sure whether he will be able to sit down and think, 'Is it what I really want or I just want to put myself through it because I have said I am going to do it?'

"We've got to find out where his desire is for Rio right now. For us, as a team, and a nation we all want him there so hopefully we can convince him to carry on."

Wiggins has won four golds, one silver and three bronze medals at the Olympics.
