Lance Armstrong is getting back on his bike, determined to win an eighth Tour de France. Armstrong's return from cancer to win the Tour a record seven consecutive times made him a hero to cancer patients worldwide and elevated cycling to an unprecedented level in America. The 36-year-old Armstrong told Vanity Fair in an exclusive interview posted on its Web site on Tuesday that he was inspired to return after finishing second last month in the Leadville 100, a lung-searing 100-mile mountain bike race through the Colorado Rockies. “This kind of obscure bike race, totally kick-started my engine,” he told the magazine. “I'm going to try and win an eighth Tour de France.” Cycling and particularly the Tour have missed his star power, even though he has been a controversial figure at times. The 2009 Tour “is the intention,” Armstrong's spokesman Mark Higgins told The Associated Press, “but we've got some homework to do over there.” Tour director Christian Prudhomme did not return messages seeking comment on Armstrong's decision. His staff said he would not comment before Wednesday, if at all. Armstrong's close friend and longtime team director, Johan Bruyneel, now with team Astana, sent a text message to an AP reporter in Paris saying he did not want to comment now. In a video statement on his foundation's Web site, Armstrong said details – such as a team and schedule – will be announced on Sept. 24 at the Clinton Global Initiative in New York City. “I am happy to announce that after talking with my children, my family and my closest friends, I have decided to return to professional cycling in order to raise awareness of the global cancer burden,” Armstrong said in a statement released to The Associated Press. “This year alone, nearly eight million people will die of cancer worldwide. ... It's now time to address cancer on a global level.” In the Vanity Fair interview, Armstrong told the magazine he's 100 percent sure he's going to compete in the Tour next summer. “We're not going to try to win second place,” Bill Stapleton, Armstrong's lawyer and longtime confidant, told the AP. Armstrong noted in the magazine interview that other athletes in his age range are competing at a high level, specifically 41-year-old Olympic medalist swimmer Dara Torres of the US and 38-year-old Olympic women's marathon champion Constantina Tomescu
