TOUR DE FRANCE

* Earns a second Tour victory and wins a bronze medal for the individual time trial at the 2000 Sydney Olympics.
* In 2001 he becomes only the fifth man in 88 editions of the Tour to win three or more times in succession following Louison Bobet (1953-55), Jacques Anquetil (1961-64), Eddy Merckx (1969-72) and Miguel Indurain (1991-95).
* Takes his fourth Tour title in 2002 - one short of the record held by Anquetil (France), Merckx (Belgium), Bernard Hinault (France) and Indurain (Spain). Wins four stages and wears the yellow jersey continuously after taking it on stage 11.

* In 2004 he wins a record sixth Tour de France after taking control of the yellow jersey with victory on the 15th stage.
* Retires in 2005 after winning the Tour for an unprecedented seventh consecutive time.
* May 31 2006 - Armstrong is cleared of doping by an independent investigation launched by the International Cycling Union (UCI) after French newspaper L'Equipe published allegations that six of his urine samples from the 1999 Tour showed traces of the blood-boosting drug erythropoietin (EPO).
BACK ON THE BIKE
* Sept 9 2008 - Armstrong announces he will come out of retirement to compete in the 2009 Tour de France to raise awareness of the global cancer burden.
* Finishes third in the 2009 Tour de France behind Spain's Alberto Contador and Luxembourg's Andy Schleck. Returns a year later to finish 23rd after a crash in the first mountain stage brought an end to any hopes of a title challenge.
* In his last race, Armstrong finishes 65th overall and almost six minutes adrift of race winner Cameron Meyer of Australia in the 2011 Tour Down Under as continued allegations over illegal doping overshadowed his swansong.
* Announces second retirement from competitive cycling on Feb 16, 2011.
DOPING ALLEGATIONS RETURN
* June 2012 - USADA officially charges Armstrong with doping, based on blood samples from 2009 and 2010, and testimonies from other cyclists. Armstrong was charged in a letter from USADA, along with five others, including former team manager Johan Bruyneel.
* On July 9, Armstrong files lawsuit against the USADA, which a federal court judge threw out later the same day. The following day he files a revised lawsuit, once again asking to stop the agency from stripping his seven Tour de France titles and banning him from the sport for life if he failed to submit to arbitration over alleged doping violations.
* Armstrong's lawsuit claimed that the USADA did not have jurisdiction and that his right to due process was being violated but it was thrown out by U.S. District Judge Sam Sparks on Aug 20, who upheld the USADA's jurisdiction in the case.
* Aug 23 - Armstrong says he is ending his fight against the USADA, but maintains they lack jurisdiction to strip him of his Tour de France titles.
