LANCE Armstrong's bid to block an investigation into whether he took performance-enhancing drugs has been dismissed in a US federal court.
The seven-time Tour de France winner was charged by the US Anti-Doping Agency in June with using performance-enhancing drugs going back 16 years.
Armstrong, 40, subsequently took legal action against the USADA, accusing it of offering "corrupt inducements" to other riders to testify against him.
The Texas court ruling means Armstrong will now have to face the doping charges. He could lose his record-breaking seven Tour de France titles if found guilty, and banned from cycling.
