Former champion cyclist Lance Armstrong has apologised to the staff of the cancer foundation he started, the same day Oprah Winfrey was scheduled to interview him in what is widely expected to be his first admission of doping.
"He had a private conversation with the staff, who have done the important work of the foundation for many years," Livestrong Foundation spokeswoman Katherine McLane said on Monday.
"It was a very sincere and heartfelt expression of regret over any stress that they've suffered over the course of the last few years as a result of the media attention," she said.
The apology came as Armstrong was scheduled to tape an interview with Winfrey to air on Thursday, his first interview
since being stripped of his seven Tour de France titles.
USA Today reported on Saturday anonymous sources as saying the disgraced cyclist plans to admit in the interview to doping throughout his career.
McLane declined to comment on whether Armstrong will admit to doping during the interview.
"Armstrong will address the alleged doping scandal, years of accusations of cheating, and charges of lying about the use of performance-enhancing drugs throughout his storied cycling career," according to a press release from Winfrey that called the event a "no-holds-barred interview."
Armstrong has always vehemently denied using performance-enhancing drugs and has never been proven to have tested positive.
But an October report from the US anti-doping body USADA cited Armstrong's involvement in what it characterised as the "most sophisticated, professionalised and successful doping program that sport has ever seen," involving anabolic steroids, human growth hormone, blood transfusions and other doping.
Less than two weeks later, Armstrong's seven Tour de France victories were nullified and he was banned from cycling for life after the International Cycling Union ratified the USADA's sanctions against him.
Armstrong, a survivor of testicular cancer, stepped down as a Livestrong board member in November. The foundation,
originally called the Lance Armstrong Foundation but known informally for years as Livestrong, formally dropped Armstrong's name from its title in October.
The foundation advocates for cancer survivors and their families and provides free services to help people affected by cancer cope with financial, emotional and practical challenges.
Armstrong founded the organisation in 1997.
The foundation says it has issued 87 million of its well-known yellow bracelets to raise funds, and as a symbol of the fight against cancer.
Livestrong on Monday said that the goal of its activities has never been to protect its founder. Those comments came in a statement responding to a New York Times article that said the foundation "engaged in some deals that appeared to have benefited him and his associates."
