As usual, the race began with a short prologue and featured a long individual time trial.

Besides, riders also had to face several mountain stages in the Swiss Alps, including the Grimselpass, a 12.1 kilometres long climb with an average gradient of 6.6% and slopes at 10%.

The race also visited the neighbouring countries of Liechtenstein and Austria.

The four top finishers of the 2006 edition, Jan Ullrich, Koldo Gil, Jörg Jaksche and Ángel Vicioso did not take part in 2007, as in one way or another they were all affected by the Operación Puerto affair.
