Signage for the Livestrong Foundation appears at the charity's headquarters, Sunday, Jan. 13, 2013, in Austin, Texas. In what's been billed as a "no-holds barred" session, Lance Armstrong is expected to reverse course after a decade of denials and apologize for doping, as well as offer a limited confession about his role at the head of a long-running scheme to dominate the Tour de France with the aid of performance-enhancing drugs, in an interview Monday with Oprah Winfrey.
