Cyclist Lance Armstrong has decided to stop fighting charges that say he took drugs to make him perform better.
The accusations that he took drugs started in 2006 when his team mate tested positive and said the whole team, including Lance Armstrong were taking them.
He's always denied it and has never failed a drugs test. He says he's innocent but won't fight the charges anymore.
The US anti-doping agency have brought charges against him that go back to 1996, they say his former team mates have given evidence against him.
The agency will ban Armstrong from cycling for life and want to strip him of his seven Tour de France titles.
