2003 Tour de France

It has no overall winner—although American cyclist Lance Armstrong originally won the event, the United States Anti-Doping Agency announced in August 2012 that they had disqualified Armstrong from all his results since 1998, including his seven Tour de France wins from 1999 to 2005; the Union Cycliste Internationale has confirmed this verdict.

Due to the centennial celebration, this edition of the tour was raced entirely in France and did not enter neighboring countries.

There was a special Centenaire Classement prize for the best-placed in each of the six stage finishes which match the 1903 tour – Lyon, Marseille, Toulouse, Bordeaux, Nantes and Paris.

Before the race, it was believed that his main rivals would include Iban Mayo, Aitor González, Tyler Hamilton, Ivan Basso, Gilberto Simoni, Jan Ullrich, and Joseba Beloki but Armstrong was the odds-on favourite.

The highest point of elevation in the race was 2,642 m (8,668 ft) at the summit of the Col du Galibier mountain pass on stage 8.

Leipheimer dropped out, Hamilton continued and got fourth place in the end while riding with a broken collarbone.

In the Alps, Gilberto Simoni and Stefano Garzelli, first and second in the Giro d'Italia earlier the same year, could not keep up with Lance Armstrong and the other favourites.

[15] The crash was a result of a locked brake, caused by a lack of traction from melting tar on the road, which led to the tyre coming off the rim.

[19][20] Later that day it was confirmed in a USADA statement that Armstrong was banned for life and would be disqualified from any and all competitive results obtained on and subsequent to 1 August 1998, including forfeiture of any medals, titles, winnings, finishes, points and prizes.

[1] On 22 October 2012, the Union Cycliste Internationale endorsed the USADA sanctions, and decided not to award victories to any other rider or upgrade other placings in any of the affected events.

[25] There was special classification, the Centenaire, which combined times of riders across the six stages involving cities visited during 1903 Tour.

[27] There were also two special awards each with a prize of €5000, the Souvenir Henri Desgrange, given in honour of Tour founder and first race director Henri Desgrange to the first rider to pass the summit of the Col du Galibier on stage 8, and the Souvenir Jacques Goddet, given in honour of the second director Jacques Goddet to the first rider to pass the summit of the Col du Tourmalet on stage 15.
