Wiggins undecided over Rio
Bradley Wiggins says it is too soon for him to consider the prospect of mounting a challenge for gold at a fourth Olympic Games in Rio.
Wiggins, whose seven Olympic medals - including four golds - place him alongside Sir Chris Hoy as Britain's most decorated Olympians, became the first man to win Olympic gold and the Tour de France in the same year in 2012.
But he has not yet looked into the possibility of mounting a fourth charge at the Games in Brazil in 2016, when he will be 36.
"We'll see - it's a long way away," Wiggins told Sky Sports News. "We tend to work in very short blocks and get the most out of those blocks, and then as you come towards the end of that block you decide what you want to do for the next period, however long that is - one or two years.
"The foreseeable future is just to concentrate on 2013 and go from there, never looking too far ahead, taking short steps and working to the goals in front of you."
For now, Wiggins admits the Tour de France remains the pinnacle of his sport and he is keen to remain in the frame to defend his title in 2013, despite early reports that Chris Froome, second behind Wiggins in the 2012 Tour, would be installed as Sky's team leader in France while Wiggins concentrates on the Giro d'Italia.
"The last four years, all the focus has been on the Tour de France and trying to win that race," Wiggins added. "Obviously it's deciding what you want to do next - the Tour of Italy is something I would like to win. In cycling terms it's just as big as the Tour for me.
"But also, going back as defending champion next year, to try and win a second Tour de France…we're very fortunate at Team Sky that we have two people that can win the Tour de France, and having two people equally as strong to beat the likes of [Alberto] Contador and Andy Schleck is going to work to our favour.
"It could be any one of us - it may be Chris Froome on the day, it may be me. You just don't know in this sport, and we're six months away from that decision being made.
"But I think once we get on the line and whoever that happens to be we all have a professional obligation, and as we saw last year with what Chris did for me, it could be that I'm doing that for him next year."
