One of the greatest professional cycling legacies has come to an unfortunate end. Seven-time consecutive Tour de France champ Lance Armstrong has decided to give up his battle with drug accusations from the U.S. Anti-Doping Agency, which resulted in a lifetime ban from the sport he helped popularize.

The USADA was quick to take Armstrong’s decline to submit to their arbitration process as an admission of guilt, which has cost him his seven Tour de France titles. Armstrong, who retired last year, insisted that his decline wasn’t an admission to using performance enhancing drugs, but because he through the process is unfair.

“There comes a point in every man’s life when he has to say, ‘Enough is enough.’ For me, that time is now,” Armstrong said in a statement, CBS LA reports. “I have been dealing with claims that I cheated and had an unfair advantage in winning my seven Tours since 1999. The toll this has taken on my family and my work for our foundation and on me leads me to where I am today – finished with this nonsense.”

“USADA cannot assert control of a professional international sport and attempt to strip my seven Tour de France titles,” he added. “I know who won those seven Tours, my teammates know who won those seven Tours, and everyone I competed against knows who won those seven Tours.”
