Amaury Sport Organisation (ASO) refused to comment over the embarrassing slip-up with releasing the race route, which gets underway in the Belgian town of Liege on June 30.

The page is no longer accessible but Dutch journalist Stephan van der Zwan has some images he took of it on www.Wielerland.nl, the website that revealed the error.

The 2012 Tour De France will feature nine flat stages, five mountain stages including two finishing at altitude, two individual time-trials and a prologue. There will also be two rest days.

The official unveiling of the route is "due" to take place in Paris on October 18.
