In this July 24, 2005 file photo, Lance Armstrong, of Austin, Texas, center, waves from the podium as his son Luke, rear right of Armstrong, his twin daughters Grace, center right, and Isabelle, center left, look on, after winning his seventh straight Tour de France cycling race, during ceremonies on the Champs-Elysees avenue in Paris, after the 21st and final stage of the race between Corbeil-Essonnes, south of Paris, and the French capital. For Armstrong, who famously insisted he was the world's most-tested athlete during his glory years but who has never tested positive for cheating, the welcome back to a still largely-suspicous France may not be warm.
