Graphic: from Monaco to Paris, the 2009 route

Lance Armstrong has given the broadest indication yet that he will try to win an eighth Tour de France next summer, but he has also expressed his fear that he could be the victim of physical assaults by spectators if he does.

The American, 37, whose Astana team are seeking talks with Tour officials before confirming his return to the sport’s blue riband event, said: “There are some aggressive, angry emotions. If you believe what you read, my personal safety could be in jeopardy.

“Cycling is a sport of the open road and spectators are lining that road. I try to believe that people, even if they don’t like me, will let the race unfold.”

Asked if he feared being attacked, Armstrong said: “Yeah. There are directors of French teams that have encouraged people to take to the streets . . . elbow to elbow. It’s very emotional and tense.”

Armstrong retired from the saddle in 2005 after claiming his seventh Tour victory and although Astana were banned from this year’s event because of doping issues, they have been told they will be readmitted when the 2009 race starts on July 4.

Armstrong is expected to begin his comeback at the Tour Down Under in Australia in January and then compete in the Tour of California.

The man who beat testicular cancer to become the most celebrated cyclist in his sport is also one who has raced under a cloud of suspicion and allegations, but he has again denied any wrongdoing. “The level of scrutiny I’ve had throughout my career from the press and anti-doping authorities is unmatched,” he said.

“I’m not afraid of anything. I’ve got nothing to hide. There are no secrets. To the critics, I would say, believe it or not, there are exceptional athletes out there: Michael Phelps, Paula Radcliffe . . .”

Armstrong has said that when he returns he will subject himself to daily tests by an independent analyst who will post the results online.
