Former cyclist Lance Armstrong decided to come clean about his use of performance enhancing drugs that helped him become one of the world's most renown cyclists.

In his highly anticipated sit-down with Oprah Winfrey on Thursday night, Armstrong admitted to doping throughout his illustrious career, which included his seven Tour de France titles.

"I view this situation as one big lie that I repeated a lot of times," Armstrong told Winfrey. "I know the truth. The truth isn't what was out there. The truth isn't what I said."

The 41-year-old disgraced athlete also added that his decision wasn't cheating since he saw it as merely to level the playing field. "I didn't invent the culture, but I didn't try to stop the culture," he remorsefully expressed. "It just gets going and I lost myself in all that."

Armstrong previously said he stopped using drugs in 2005, and competed in the Tours de France in 2009 and 2010 completely drug-free. He placed third in 2009 and 23rd in 2010.
