Armstrong warns son not to repeat 'doping mistakes' or risk getting f***ed

Former cyclist Lance Armstrong has said that the best advice he would give to his son is to avoid repeating his doping mistakes at all costs, otherwise he's 'f***ed'.

According to the Courier Mail, Armstrong said he's still working hard to mend a thousand broken fences and said while some people have accepted his apologies, maybe he need to say sorry a thousand more times.

He also said he'd make sure his son never repeated his mistakes, according to the report.

Armstrong's biggest fear after the Oprah interview was that his children would be exposed to ridicule, the report said.

The disgraced former cycling star and cancer campaigner revealed a career tainted by doping when he sat down with Oprah Winfrey in an explosive interview in January, the report added.
