Kitzbüheler Horn is a high mountain pass at an elevation of 1.996m (6,549ft) above the sea level, located in the Kitzbühel Alps in Tyrol, Austria. It’s one of the toughest climbs in international cycling.
The road to the summit is paved. It's impassable from November to May. The final 2,2 km of the Kitzbüheler Horn are on a privately owned and car-restricted road owned by the ÖRF (the National Austrian Broadcasting Company). The width of the road there is only one meter, with a maximum gradient of 22,5%. The climb ends just a few meters below the 1,996 m peak of the Kitzbüheler Horn, at the foot of the TV towers and with a final narrow, steep section at 19%.
Starting from Höglern, the ascent is 9.7 km long. Over this distance, the elevation gain is 1.250 meters. The average percentage is 12.9 %. At the summit there is a 102 metre high TV tower belonging to the ORF and known as the Kitzbüheler Horn Transmission Tower (Sendeturm Kitzbüheler Horn). It’s the steepest mountain cycle race in Austria. 865 meters vertical rise in only 7.1 km long is a challenge which means an average gradient of 12.5%. On the last kilometre, just above the Goinger Alm, is the most difficult "ramp" with exactly 22.3% slope.
