Lance Armstrong admitted doping during an interview with Oprah

Lance Armstrong and Oprah Winfrey

On Tuesday, during an interview with one of the most influential people in the world, Oprah Winfrey, former cyclist Lance Armstrong admitted  using drugs to enhance sport performance.

The New York Times and USA Today said on Monday, day where Armstrong recorded the interview of two hours and a half, that he had admitted to Winfrey to have used banned substances during his career.

Winfrey said that as part of the terms for the interview, agreed with Armstrong, the seven-time winner of Tour de France, that none would talk about what was said in the interview to “let people draw their own conclusions.”

Since the International Cycling Union (UCI) deleted its records from the  books, the Sunday Times of Britain sued Armstrong for more than £ 1 million ($ 1.6 million) after having paid 300,000 pounds for defamation, in 2006, for publishing a story that suggested his doping. A Texas insurance company has also threatened to take legal action to recover millions of dollars in bonuses paid by multiple victories.

According to some scholars, athletes could be exposed to criminal cases, in addition to the money from their first victories that would have to be repaid. After being punished, Armstrong lost most of his sponsors and had cut ties with his foundation to fight cancer, Livestrong.

This is the first time Armstrong, 41, talks about The subject, with the press since October when he was stripped of his seven Tour de France titles (1999-2005), after the U.S. Anti-Doping Agency (USADA) affirmed he  helped organize the most sophisticated doping program in the history of sport.
