This was the 6th coup in my "seven summit Speed" program, the ski speed climb of Denali 6.194m (Mr. McKinley) in 16h45min starting at the airfield of the Kahiltna glacier. The 4.500 meters climb via the "west Buttress" counts 15 miles (24 Km), technically simple and therefore ideal for a speed climb with skies. From the airfield on the Kahiltna glacier (2.1780m) a first descend of 200m via "heartbreaker" hill followed by the pretty flat "Eleven Camp". (from: 11.000 feet Camp equals approx. 3.200 m), via "Windy Corner" to "Routeen Campt" onwards to "Seventeen Camp" and the Denali Pass to the football field. After a small counter ascend and the summit inclination and finally the summit ridge to the highest point of North America.
