The U.S. Anti-Doping Agency is set to file doping charges against Seven-time Tour de France winner Lance Armstrong over claims he used performance-enhancing drugs during his record-breaking career.

If the charges are up held Armstrong will be banned from competing in his current incarnation as a triathlete while the process takes place - and stripped of his record seven Tour titles if found guilty.

Throughout his career Armstrong has been dogged by accusations of cheating and foul play. Although he has never failed a drug test and has repeatedly denied ever cheating.

Lance Armstrong strongly denied these allegations and in a statement said "I have never doped, and, unlike many of my accusers, I have competed as an endurance athlete for 25 years with no spike in performance, passed more than 500 drug tests and never failed one. That USADA ignores this fundamental distinction and charges me instead of the admitted dopers. That says far more about USADA, its lack of fairness and this vendetta than it does about my guilt or innocence.
