Lance Armstrong stated , In Oprah interview, that he rode clean in 2009
and 2010 tour. He finished third in 2009 behind Astana teammate Contador.
I believe Contador tested positive for clenbuterol and later plastic residue was
detected in his blood sample indicating blood doping . Considering Armstrong and Contador were teammates that year ( they raced and trained together )surely
this is a topic that should have been addressed in interview. There was quite a bit of tension that season between Armstrong and Contador. Contador performed like a rider on PED's (ie EPO). I tend to think that Lance probably raced clean in 2009 and knew that his teammate Contador was dirty. After all his admissions Lance has nothing to gain by lying about 2009. So perhaps the 2009 tour was a race where a clean Armstrong got beat by a dirty rider.
