Cycling legend Lance Armstrong says recent allegations for his doping won't distract him from his goal to win a record eighth Tour de France before ending his professional career.

The 38-year-old Armstrong said Thursday that he was in a better shape than last year and he won't let any accusation from former teammate Floyd Landis deter him, according to the Associated Press.

The Tour starts on Saturday in the Dutch port of Rotterdam with an 8.9-kilometer prologue. The seven-time Tour de France champion Armstrong confirmed it will be his last Tour.

Landis, who was stripped of the 2006 Tour de France title for doping, recently claimed in e-mails to cycling officials and sponsors that Armstrong tested positive for EPO at the Tour de Suisse in 2002 and paid off former International Cycling Union boss Hein Verbruggen to keep it quiet. Armstrong won the 2001 Swiss race, but did not compete there in 2002.
