Former cycling champion Lance Armstrong has said he 'wouldn't change a thing' about the doping that led to him being stripped of his record seven Tour de Francetitles, according to details of an interview that will air next week on NBCSN.

The network, owned by NBC Sports Group, said on Thursday it would broadcast a 30-minute interview next Wednesday called 'Lance Armstrong: Next Stage' in which the 47-year-old American discusses his career and the decisions he made.

'We did what we had to do to win. It wasn't legal, but I wouldn't change a thing: whether it's losing a bunch of money, going from hero to zero,' said Armstrong, who overcame cancer to win the first of his seven consecutive Tour de France titles 20 years ago, said in an excerpt of the interview provided by NBC Sports.

Armstrong was stripped of his Tour de France titles and banned from the sport for life in 2012 after the International Cycling Union ratified the US Anti-Doping Agency's sanctions.
