The Critérium du Dauphiné Libéré, named after the daily newspaper of the French Alps just after World War II, celebrates 60 years of existence this year. It's a family affair; created and run for a long time by Georges Cazeneuve, the event has been under the guidance of his nephew, Thierry, a respected cycling journalist, for the past 20 years.
As a result of this long tradition, all the great champions of modern history have used the Dauphiné as a rehearsal for the Tour de France: same venue in the Alps, same mix of prologue, sprint, breakaway, long time trial, uphill finish and high mountain stages, but all grouped into one week, from Sunday to Sunday.
Nowadays, probably even more than in the past, the Dauphiné remains a Tour contender's favoured preparation race, alongside the Tour de Suisse (Tour of Switzerland). It's highly prestigious, the standard of the race has been significantly reinforced by the concept of the ProTour, but so close to the Tour, less than one month before the start, every move is interpreted in relation to the Tour, with top favourites hiding their strength or potential Tour contenders spending too much energy to win.
