** FILE ** In this May 15, 2007 file photo, cyclist Floyd Landis listens to testimony during his arbitration hearing on the doping allegations against the 2006 Tour de France champion at Pepperdine University in Malibu, Calif. Landis has retired from professional racing, saying the battle to fix the sport's drug-tainted image is "not my fight." Landis told ESPN.com late Monday, Jan. 17, 2011, that he "spent five years trying to get back to a place that I can never really go back to, and it's causing more stress than is worth it." less
