It would be interesting to know what percentage of Tour of riders were NOT on EPO before there was a test for it. Of the top contenders I think everyone is agreed it would have been 0% who were not using it. But what of the peloton as a whole? 5%? 10%? Maybe that's too harsh and it was 50% not doing it? What do you reckon?
Who knows!!
I am not trying to spoil the question you ask - as it would be interesting to know, but it breeds speculation with some suggesting everybody. The answer is no-one knows for sure.
I would rather look at proven facts to try and gauge the use.
An example- of the 9 riders on Festina Bassons was not on the program. Does that suggest that 11% were clean?
A Swiss anti-doping expert said some years ago that 80% of the samples showed signs of PED use. This was generally reported as 80% of the peloton using PED's. But we know that the podium places amount for a large number of tests - so this would be a) often the same riders b) just the highest placed riders - so unfortunately it is not a representative analysis.
Anne Gripper said recently that the vast majority of the 800 riders on the passport had very normal values.
So the answer is ..... no-one know.
