Lance Armstrong relaxes on Monday before restarting his campaign for Thomas Voeckler's yellow jersey on stage 15

Australia's Robbie McEwen smiles as he rides to the start of the 180.5 km stage from Valr�as to Villard-de-Lans

Thomas Voeckler, holder of the yellow jersey with a slim overall lead over Armstrong, starts beside Sandy Casar

Richard Virenque makes an early break but is hotly pursued by the US Postal team who are leading the charge in the peleton

The pressure seems to be telling on Voeckler as he slides down the field some six or seven minutes behind the leaders

Virenque's early breakaway is repeated at the Col de l'Echarasson climb, where Jan Ullrich pulls a minute clear

Armstrong stays in contention, reels in Ullrich and then overtakes Ivan Basso 200m from the line to take the stage

Armstrong celebrates another yellow jersey and shifts his sights onto the road to Paris and a possible sixth Tour title
