This is probably the hardest climb in professional cycling together with the Alto de Angliru and the Monte Zoncolan.
Over the years there have been some very prominent winners in the Queen stage of the Tour of Austria - such as Cadel Evans, Danilo di Luca, Miguel Angel Lopez and the record-holder Victor de la Parte (Movistar). Hans Peter won this stage 18 years ago in 2002!
The climb is very steep - even through the corners. However, the effort is worth the reward; a sensational panoramic view to the famous "Wilder Kaiser" mountains and to Kitzbühel and the Hahnenkamm mountain (where the most difficult ski alpine downhill race is held every year). Kitzbühel itself is something like the capital city of the jetset - especially in winter.
