Berzin said:The tests aren't always administered the way we think.
Case in point-when Roberto Heras got busted at the Vuelta, he made a big deal about testing positive so near the end of the race, when he had the victory already in the bag.
Part of his defense was how he had been tested as race leader a few times before and nothing ever came up. So why would he dope so close to the end of the race when he was assured of the overall victory?
We later find out that (and please remember the Vuelta is one of the three grand tours on the racing calendar) that none of the previous samples were ever tested. They were just collected. When those previous samples were tested after the first positive, they also came up for EPO. He had been riding dirty the whole time.
The excuse why the previous samples were never tested boiled down to the costs of each individual test. Meanwhile, Heras was riding those days thinking he had passed those tests and was basically home free.
The moral of this story? There is a big difference between what we are told and what actually occurs.
My informations tells me the labs got so tired of A samples being washed away with a TUE or a borderline result by the UCI the labs started leaking the A sample. Hence Floyds positive A sample was leaked. They had to. There's no way the UCI would have allowed the TDF champion to test positive. Not after Puerto.
