The 2007 Tour de France will begin in London on Friday. A presentation of the riders and the time trial prologue stage will be held the day after. But, due to doping allegations against American Floyd Landis, there will be no defending champion this year.

Determined to stamp out doping, the Union of Cycling International has drawn up a charter. It demands cyclists participating in the race submit to regular testing so that changes in their performance and body chemistry can be spotted.
