Olympic team pursuit champion Geraint Thomas has said that the 2012 London Olympics could be his final appearance on a track.
The Welshman will instead focus on road races, an area in which he has had much recent success.
Thomas, 25, wore the white jersey for best young rider in the opening seven stages at this year's Tour de France before finishing 31st - the highest-placed British rider.
He was also part of the GB team that helped Mark Cavendish win the world road race title at the end of the last month.
Speaking of the London games, the Team Sky rider said: "That could then be the end of my time on the track.
"Four years is a long time in sport, anyway, and for a year or so after the London Olympics I will be totally on the road."
The 2012 Games begin on July 27.
