Floyd Landis

American Floyd Landis became the first Tour winner to fail a drugs test after testing positive for the male sex hormone testosterone during the 2006 Tour.

Landis denies using performance-enhancing drugs and is hoping to overturn the US Anti-Doping Agency's 34-0 winning record on arbitration hearings and prove he did not take testosterone on his way to victory.

Landis says the French lab which tested his samples made key errors.

His 2006 victory is not recognised by Tour de France organisers.

Jan Ullrich

Ullirch was forced out on the eve of last year's race after being linked to "Operation Puerto" – a massive Spanish investigation into a blood-doping scandal at a Madrid clinic that implicated more than 50 riders.

After he was fired by the T-Mobile team, Ullrich's DNA sample was matched to one of the blood bags in the scandal.

The 1997 Tour winner has retired and denies any wrongdoing.

Ivan Basso

The Italian rider was also kicked out of last year's Tour. He received a two-year doping penalty from his cycling federation in June and accepted the punishment. The 2005 Tour runner-up has confessed to "attempted doping," but says he never actually went through with it.

Richard Virenque

The flamboyant French rider is a seven-time winner of the King of the Mountains jersey as best climber.

Virenque was part of the Festina squad kicked off the Tour in 1998 after police found large quantities of doping material in a team car.

Members of the team were arrested at the French border before the start of the event.

Virenque was banned for nine months, team director Bruno Roussel and medical team member Willy Voet were fined and given suspended jail sentences.

Virenque, now a minor television celebrity, later made a tearful confession to a French court that he had used banned substances.

Bjarne Riis

The Dane recently confessed to using EPO during his 1996 Tour win.

Now head of Team CSC, he decided not to join the team for the start of the race in London on July 7.
