Bernhard Kohl hit by extended ban until 2014

Kohl won the King of the Mountains jersey and finished third overall

Retired Austrian cyclist Bernhard Kohl has had his ban for taking a blood booster extended, ruling out an unlikely return until 2014.

His ban for taking Cera was due to expire on 3 July but Austria's anti-doping body has increased the penalty.

Kohl, 28, won the King of the Mountains jersey on the 2008 Tour De France and was third overall, but later admitted he had taken an illegal substance.

The climbing specialist retired from the sport in May 2009.

At the time of his original two-year ban, Kohl said he had "succumbed to temptation" in taking Cera, a version of blood booster EPO.

"I have only myself to blame for this mess," he said in 2008.

"I had a bad feeling to have cheated so many fans and all of Austria, so many young people who became enthusiastic about the sport because of me.

"It was not a good feeling and that's why I'm relieved the truth is out.

"I thought this medication could not be traced but it could be traced. I hope every medication can be traceable in future. I would like to play my part so the sport becomes cleaner."
