Alejandro Valverde is a former Spanish Champion and has never tested positive. Blood bags with the name of his dog written on them were found in the freezer of the famous doping expert Dr. Fuentes in Spain. The Italians obtained a sample of the frozen blood and compared it to a sample taken in an Italian race and found Valverde guilty and then banned him from racing in Italy and threatened to charge him with criminal charges if he stepped foot on their soil thereby keeping him from both the Giro and le tour (there was one stage that ended in italy that year). The Spanish federation investigated the whole affair as Operacion Puerto but did not suspend him as there was no proof that he was doping. Only that his blood was in a doping doctor's freezer. The Italians took that decision to CAS who suspended him for two years. One of the other names on the blood bags was Jan Ulrich's dog's name. Another bag was labelled "cowboy". I wonder who that would refer to? While all of this crap was going on Valverde raced and won the Vuelta and a couple of major races. He has not lost those titles as he did not test positive during the races that he won. AC will likely have the tour victory last year struck if he loses at CAS. Maybe that's why his lawyers are playing games so that he can win the tour and the giro this year and maybe go for the vuelta before his case is heard.
One point that may not be clear judging by the comments above is that the Swiss lab did not cover up the test. The UCI is the body that asked that no further steps be taken on the 'suspicious' tests and the lab did what they were told by the sport's governing body.
Let's face it, they all dope or at least the ones who are in the upper 25% of the peleton are on some form of PEDs be it EPO, Insulin, HGH, or roids. The dopers are head and shoulders above the level of testing capable of detecting PEDs.
The sport I've followed and loved for 40 years is now officially a joke.
