TOUR BOSS DEMANDS DOPING OVERHAUL !

Vinokourov won two stages within three days this week. Tour director Christian Prudhomme says professional cycling needs a complete overhaul in the wake of the latest drugs scandal to rock the sport.
Kazakh rider Alexandre Vinokourov tested positive for blood doping after winning Saturday's time-trial stage.
And Prudhomme said: "This has to change now. The re-conquering of cycling has to be done with the Tour de France.
"I started this job believing that we could change this system but it's not enough: there has to be a revolution."

Team Astana withdrew from the race following Vinokourov's positive test for a banned blood transfusion.
The 33-year-old, who won Saturday's time trial in Albi, reportedly had two different kinds of red blood cells, indicating he has taken blood from someone of a compatible group.
Wednesday's 16th stage suffered a minor delayed when members of eight teams protested.
Six French teams, plus German outfits Gerolsteiner and T-Mobile have formed a Movement for a Credible Cycling, asking for all teams to abide by their good behaviour charter of 2005.

BLOOD DOPING EXPLAINED
What is it?

Administration of red blood cells to increase the blood's oxygen-carrying capacity

How is it done?

Injection with someone else's red blood cells; removing own blood, storing it and returning it once body has replaced it

Why do it?

The better the blood's oxygen-carrying capacity, the greater one's enduranceSide effects: Blood clots, overload of circulatory system, kidney damage, transmission of infectious diseases such as HIV.

Chances of being caught:

Test can only detect it if the blood comes from a donor.

Under the charter, teams are requested to avoid fielding riders implicated in doping affairs.
Even before Tuesday's bombshell, Tour leader Michael Rasmussen was battling suspicions for missing pre-tour doping tests, although he still seems likely to claim victory in Paris on Sunday.
And it comes on top of 2006 champion Floyd Landis being prevented from defending his crown for failing a drugs test during last year's Tour while Giro d'Italia winner Danilo di Luca is also being investigated.
In addition, 2006 Giro winner Ivan Basso was recently handed a two-year ban and 1996 Tour de France winner Bjarne Riis admitted using performance-enhancing drugs, as did former Telekom team-mates Eric Zabel, Udo Boelts, Bert Dietz, Christian Henn and Rolf Aldag.
Prudhomme expressed his disappointment over the latest setback and urged riders to remain clean for the good of the sport.
"The start in London was a formidable occasion to re-conquer," he said. "But there has been an absolute failure of the system.
"The riders have to understand that they are playing a game of Russian roulette if they are doping.
Everyone has been suspicious of the Astana team - Bradley Wiggins"They have to realise that we will never give up the war against doping in which we are involved.
"Doping ruins our childhood dreams. Vinokourov has cheated and the only possible answer was - leave."
Britain's Olympic track champion Bradley Wiggins revealed he had suspicions over Vinokourov's performance in Saturday's time trial.
"I know that to put two minutes into me what power Vino would need and the effort he would have had to make and it didn't add up," he told the Guardian.

Prudhomme is demanding action after the latest drugs scandal"At the time I was frightened of what I might say. I didn't want to accuse people because they had beaten me outright.
"But when you saw him limping the week before you couldn't help thinking about it. I think everyone has been suspicious of the Astana team.
"It is a disaster for the sport. There will be no cycling in 10 years if this goes on."
Fellow Briton David Millar, who has been an outspoken campaigner against doping since serving a two-year ban for using erythropoietin, believes cycling would take "five to 10 years" to get out its drugs problem.
He said: "The bottom line is it is, it is finally good because the controls work, but I'm gutted as Vinokourov was one of my favourite riders."
Vinokourov was hotly tipped for this year's title but lost time in a bad crash on stage five and slipped further back in the stages in the Alps.
But he looked back to his best in a dominant time trial on Saturday and, although he dropped out of overall contention with a disastrous display on Sunday, he won another tough mountain stage on Monday.
