2012 Tour de France, Prologue to Stage 10

The 2012 Tour de France began on 30 June, and stage 10 occurred on 11 July. The 2012 edition began with a prologue – a short individual time trial stage – where each member of the starting peloton of 198 riders competed against the clock – in Liège, Belgium with two more stages held in the country before moving back into France. The race resumed in Orchies for the start of the third stage; also during the first half of the race, the peloton visited Switzerland for the finish to the eighth stage in Porrentruy, and contested another individual time trial stage – having returned to France – the following day.

Fabian Cancellara held the lead of the race throughout its opening Belgian leg; having won the race-commencing prologue, Cancellara defended it on the following two stages before the race returned to France. Cancellara maintained his overall lead for the rest of the race's first week, before eventually losing time on the first true mountain stage of the race – stage seven – as he was dropped on the closing climb to La Planche des Belles Filles. As a result, Bradley Wiggins assumed the maillot jaune, becoming the first British rider to wear the jersey since 2000. Wiggins maintained the lead for the following three stages, including his first victory at the Tour during the ninth stage individual time trial in Besançon. Wiggins held a lead of almost two minutes in the overall standings with the more mountainous second half of the Tour still to race. Two riders won multiple stages during the first half of the race; Peter Sagan, in his first Tour de France, won three stages and also held the lead of the points classification, while André Greipel took back-to-back stage victories on the fourth and fifth stages. World champion Mark Cavendish achieved one stage victory, while French riders Thibaut Pinot and Thomas Voeckler each took breakaway victories.
