Seven-times champion Lance Armstrong will come out of retirement and compete in next year's Tour de France, the cycling magazine VeloNews reported on Monday.
Velonews cited sources on its website as saying that Armstrong, 36, would compete in the Amgen Tour of California, Paris-Nice, the Tour de Georgia, the Dauphine-Libere and the Tour de France.
It quoted the sources as saying an exclusive article revealing the American's intentions would be published in the magazine Vanity Fair this month.
Armstrong would race for the Astana team and receive no salary or bonuses, the sources said.
Telephone calls to Armstrong's manager Mark Higgins were not immediately returned.
Armstrong won the Tour de France, cycling's most prestigious race for a record-breaking seven consecutive years from 1999 to 2005.
