Past Tour de France winners and their involvement with drugs.
From wikipedia
http://en.wikipedia.org/wiki/Doping_at_the_Tour_de_France
Many caught on more than one occasion, others declared once they retired.
The information they provide about Luis Ocana is wrong. I know he tested positive the year before he retired. Hinault was never caught, but he refused to pass antidoping controls in some races.
I wonder if there has ever been a Tour de France winner completely clean. Many say Lemond, but it just doesn';t make sense to me that a rider is able to win it when there are so many cases before and after that were at it, some of them the biggest names the race has ever produced.
If you look back until the epo era started cyclist's relied on steroid's and amphetamines to get stronger and go faster.The best rider's still won because they were the best rider's.
With epo that's not the case.Armstrong was never a gc contender until he worked with Ferrari.Riis was never going to win a tour,yet the year he did he was super strong with only Ullrich coming close to matching him.
As to Lemond ,Fignon and Hinault they were gifted cyclist's from an early age,clean or not they would have won gt's.I Don't think you can say that of other's since,possibly Ullrich.
On that list,Delgado tested positive for probenecid a masking agent for steroids which while banned by the IOC but wasn't banned by the UCI.
Roche was accused of doping by in 200 La Republica and in March that year Italian judge Oliva published a report into the Carrera team and sporting doctor's in cycling.And later in 2004 judge Oliva stated that Roche had used epo in 1993.
As to Mig,He's one of my favourite's but I don't think he won all he did while clean.
