Hoy calls time on kilo attempt

After coming agonisingly close to setting a new world record for the kilometre time trial, Chris Hoy has said that he will not make a third attempt to better Arnaud Tournant's world best of 58.875 seconds, set seven years ago on the same high altitude track in Bolivia.

"I don't plan to go for the kilo again. I gave it everything and it was so frustrating to miss it by that little margin, but that's sport and you have to accept it," Hoy told the BBC.
