Cyclist Lance Armstrong was accused of doping throughout his career and was stripped of his medals and banned from the sport in 2012. In a new interview with Oprah Winfrey, set to air Thursday and Friday, the once acclaimed athlete will reportedly admit to doping for the first time ever.

The special, "Oprah and Lance Armstrong: The Worldwide Exclusive," will simultaneously stream live on the OWN website and Oprah.com at 9 p.m. ET. Click here to watch the interview. The interviews will air in two parts on Thursday and Friday and will be until 10:30 p.m. ET both nights.

In 1997, Armstrong created the cancer-fighting charity Livestrong Foundation, known for its yellow bracelets. Following the doping charges, and Armstrong's refusal to take the case to arbitration, he was forced to step down from the Austin, Texas-based organization.

Livestrong released a statement on Wednesday saying that it hopes Armstrong will be honest in his interview with Winfrey regarding the charges against him that ultimately ended his career - the evidence released by the U.S. Anti-Doping Agency in October of 2012 resulted in Armstrong being banned from cycling and stripped of his seven Tour de France wins.

"We expect Lance to be completely truthful and forthcoming in his interview and with all of us in the cancer community," Livestrong said Wednesday, according to Metro New York. "Inspired by the people with cancer whom we serve, we fell confident and optimistic about the Foundation's future and welcome an end to speculation."

The 2014 Tour de France will being in Yorkshire, England, on July 5. Bradley Wiggins became the first British man to win the Tour last year and the Tour returns to England seven years after London hosted the race.

"We hope and trust that the 2014 Grand Départ will be just as spectacular: this is my wish," said Tour de France Director Christian Prudhomme. "And I don't think I need to worry, as it seems very likely to come true given how impressed we were with the passion and desire of our friends from Yorkshire ever since we first met."

A part of tradition, all riders who managed to finish a Tour race are invited for the final day, with a total number of invitations expected to number close to 4,000, according to The Washington Post. When asked on Thursday if Armstrong would receive an invitation, Prudhomme said, "That seems to me to be out of place now."
