New York ? Lance Armstrong is considering retiring after he tries for a record seventh straight Tour de France victory this July.

“It’s a possibility,” Armstrong said Thursday at a Central Park appearance to support New York’s 2012 Olympic bid. “I am still thinking about that.”

Comments Armstrong, 33, made to Italian media last week that he missed his kids and the pressure was taking a toll on him fueled speculation that this year’s Tour de France would be his last.

“Four more months and it’s over …,” he was quoted as saying in Gazzetta dello Sport.

His new two-year contract to race for the Discovery Channel team requires he race just one more Tour de France.

On Thursday, Armstrong said he would have plenty of responsibilities to occupy his time if he was to retire.

“I’d have a lot to do with the fight against cancer,” said Armstrong, who overcame testicular cancer to become one of cycling’s all-time greats. “That is enough to keep me busy for the next 50 years. I have three young kids that I want to be a full-time father to.”
