MOVES TUES DEC 21

Seven-time Tour de France winner Lance Armstrong awaits the start of the 2010 Cape Argus Cycle Tour in Cape Town March 14, 2010. Cycling has been struck by a crisis that threatens to wipe out most of its efforts to fight doping in a year that saw the two big names involved in scandals. Seven-times Tour de France champion Lance Armstrong is involved in a U.S. federal investigation triggered by former team mate and disgraced 2006 champion Floyd Landis's allegations, while three-times winner Alberto Contador failed a test for the banned anabolic agent Clenbuterol.
