Bradley Wiggins is hinting he may not attempt to win the Tour de France for a second time.
The defending champion withdrew from the race last month because of a knee injury.
Wiggins tells Sky TV on Friday that he doesn't know if he's willing to train for another Tour. He says he's got "other things I'm concerned with in my life, which I give more time to and there are other things within cycling I want to do."
Wiggins is in the second week of a six-week training schedule and expects to return to racing at the Tour of Poland on July 27.
