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.
