Lance Armstrong plans to admit to doping throughout his career in an interview with Oprah Winfrey next week, the American cyclist's first interview since being stripped of his seven Tour de France titles, USA Today reported on Saturday.
But Armstrong, 41, likely will not offer great detail about specific cases and events, the paper said, citing an unidentified source with knowledge of the situation.
The interview is scheduled to tape on Monday at Armstrong's home in Austin, Texas, and set to air on Thursday on the Oprah Winfrey Network.
Such an admission would mark a major reversal for the famed cyclist. Armstrong has always vehemently denied using performance-enhancing drugs and has never been proven to have tested positive.
But an October report from the U.S. anti-doping body USADA cited Armstrong's involvement in what it characterized as the "most sophisticated, professionalized and successful doping program that sport has ever seen," involving anabolic steroids, human growth hormone, blood transfusions and other doping.
