Lance Armstrong admits to doping in interview with Oprah Winfrey

Lance Armstrong has admitted to Oprah Winfrey that he used performance enhancing drugs to win the Tour de France.

A source confirmed to The Associated Press following much speculation surrounding the athlete's numerous wins.

Armstrong was stripped of his titles in October after the US Anti-Doping Agency and International Cycling Union agreed that enough evidence was brought to surface to strip his titles from the years 1999-2005.

Shortly thereafter, Armstrong stepped down from his position at the Livestrong Foundation.

According to the report, on his way to the interview he stopped at the Foundation where he apologized to staff but did not directly admit to them that he had been doping. The staff is said to have broken down in tears with Armstrong appearing choked up as well.

The AP notes that USADA chief executive Travis Tygart labeled Armstrong’s doping regimen, “The most sophisticated, professionalized and successful doping program that sport has ever seen."

The talk show mogul took to twitter to gush about her interview with Armstrong, but left no insight as to what fans could expect. “Just wrapped with @lancearmstrong More than 2 1/2 hours . He came READY!” she wrote after the interview wrapped.

Armstrong’s interview with Oprah is set to air Thursday, Jan. 17.
