Day number five dawned on the Angen Tour of California and the only thing anyone was talking about was the overnight revelations by Floyd Landis that he had used performance enhancing drugs(PED's) and had witnessed a number of racers, including Lance Armstrong, doing the same. Landis supplied names, dates and details of the drug use; the particulars were specific enough to make some believe that what he claimed was true.

At the heart of the whole affair is the credibility of Floyd Landis. For four years he has maintained that he was innocent of the doping offense which stripped him of his 2006 Tour de France title. He even wrote a book proclaiming his innocense. Now, he has done a 180-degree turn and is admitting that he used a wide spectrum of PED's. Are we to believe the 2006-2009 Floyd Landis or the 2010 Floyd Landis?

Added to all the confusion is the claim that Floyd was trying to use this information to blackmail the organizers of the Amgen Tour of California into letting his team pariticipate in this year's race.

If you believe Floyd, from 2002-2006 there was widespread doping in the pro peloton and a number of high-profile American riders besides Lance were involved. If you believe Lance and the other riders, Floyd is down to his last gasp and is just trying to take a number of people down with him as he sinks further into the abyss.

What is really missing here is proof of Floyd's claims. At this point what we have is a "he said, he said" scenario which then brings everyone's credibility into question.  Floyd's credibility is not that great. Lance's credibility seems to be pretty high. It really comes down to who do you believe.
