FILE - In this Aug. 22, 2010, file photo cyclist Lance Armstrong greets fellow riders prior to the start of his Livestrong Challenge 10K ride for cancer in Blue Bell, Pa. The nine months since a former teammate's allegations, that Armstrong cheated to win, have served only to illustrate the difficulty of translating them into legal charges. Armstrong has been tested hundreds of times over the years for banned substances, and has never been found in violation. If he were to be charged, there is a dispute over whether any forensic evidence exists that could be used against him. (AP Photo/Bradley C. Bower, File)
