At the height of his career, Lance Armstrong was one of the greatest athletes in the world—and one of its greatest heroes. He defeated testicular cancer after being given less than 50 percent odds of beating it, only to emerge as a cycling powerhouse, winning a record seven Tour de France titles. But doping allegations that dogged his superman run finally reached a crushing breaking point on Aug. 24, when the U.S. Anti-Doping Agency stripped him of his medals and banned him from the sport for life, claiming to have definitive proof that he doped throughout his career. Here, a timeline of Armstrong’s many ups and downs.

"For the level of condition that I have now, that was without a doubt the hardest physical thing I have ever done," he said afterward. Two years later, Armstrong completed the Boston Marathon in 2:50:58.

Armstrong is named the second-best Athlete of the Decade in a poll by members of the Associated Press, announced on Dec. 17, 2009. With 33 of the 142 votes cast, he finishes behind golfer Tiger Woods, who secures 56 votes. Tennis star Roger Federer finishes third and Olympic swimmer Michael Phelps fourth.

After a disastrous showing in the eighth stage of the 2010 Tour de France on July 12, 2010, Armstrong faces the hard truth: he doesn’t have a shot at winning an eighth title. He finishes in 61st place at the end of the stage, citing problems with his left hip. “Obviously, the Tour’s finished for me,” he says.

After years of denying allegations, 2006 Tour de France winner Floyd Landis admits to doping in 2010 and was stripped of his medal. On May 20, 2010, he tries to bring Armstrong down with him when an email he wrote to cycling officials leaks to the media. In the email, he says Armstrong’s longtime coach Johan Bruyneel introduced him to performance-enhancing drugs and that Armstrong helped him to understand how they worked. “Even a superficial review reveals a troubling, angry and misplaced effort at retribution by Landis for his perceived slights,” Armstrong responds through a statement on his website.

Federal prosecutors investigating doping charges against Armstrong subpoena documents on July 27, 2010, from an arbitration case that sought to prove Armstrong used performance-enhancing drugs throughout his career. Those documents contain the depositions from several of Armstrong’s former teammates, given when a promotions company was trying to prove that he was doping. While doping is not illegal, federal prosecutors are making the case that, if he was using performance-enhancing drugs, Armstrong defrauded investors by accepting sponsorship dollars under the understanding that he wasn’t doping.

After seven Tour de France victories, a bronze medal in the Olympics, multiple doping controversies, and a brief retirement, Armstrong confirms on Feb. 16, 2011, that he is retiring from cycling for good. He previously left the sport in 2005, but returned in 2009 for another go at the Tour de France. In his final career race in Australia in January 2011, he finishes in 67th place.

After retiring from cycling, Armstrong turns his attention to triathlons, competing in his first Ironman competition on Feb. 13, 2012. He turns in an impressive performance, finishing second behind New Zealand’s Bevan Docherty, who passes Armstrong at the end of the 21-km run to clinch his victory. Docherty bests Armstrong by just 42 seconds.

In an interview with 60 Minutes on May 22, 2011, another of Armstrong’s former teammates, Tyler Hamilton, accuses the cyclist of doping. Hamilton claims that Armstrong, as well as other U.S. Postal team leaders, encouraged, promoted, and took part in a doping program. In response, Armstrong’s lawyer demands an apology from the news program for insinuating that he doped: “In the cold light of morning, your story was either extraordinarily shoddy, to the point of being reckless and unprofessional, or a vicious hit-and-run job. In either case, a categorical on-air apology is required.”

Federal prosecutors announce they are dropping their investigation into whether Armstrong committed any crimes—including defrauding the government, money laundering, or drug trafficking—by doping. Prosecutors do not say why they are dropping they investigation, just that the matter was closed.

New doping charges brought against Armstrong by the U.S. Anti-Doping Agency could cost him his seven Tour de France titles. The new allegations, revealed in a letter to Armstrong on June 13, 2012, stem from blood samples collected from Armstrong in 2009-11 that were “fully consistent with blood manipulation including EPO use and/or blood transfusions.” As a result of the formal charges, Armstrong is immediately barred from competing in the Ironman triathlons.

In response to new doping allegations from USADA, Armstrong files a suit to have the organization drop the charges and the end its investigation. A judge dismisses the suit on July 9, 2012. The USADA claims to have more than 10 former teammates prepared to testify that Armstrong used performance-enhancing drugs throughout his career.

The U.S. Anti-Doping Agency strips Armstrong of his seven Tour de France medals and issues a lifetime ban from the sport of cycling on Aug. 24, 2012, effectively erasing what was widely considered one of the greatest achievements ever in professional sports. Armstrong pledges not to address the USADA and the case against him any longer. “I know who won those seven tours, and everyone I competed against knows who won those seven tours,” he says. “Nobody can ever change that.”
