The third variant on the recommendation of the expert and FIS official Mr. Miloslav Bělonožník won and in 1978, when only funds were secured for complete accompanying investments , Skicentrum, roads, tracks and more, construction has begun. The investor was ČÚV ČSTV and to a large extent MěNV Harrachov with the then chairman Mr. Václav Hadrava and in the preparation and implementation of the construction with ing. Ludvík Šablatůra. In 1980, the first race in the ski years took place on the P 120 / later marked K 180 / and in 1983 the 7th World Ski Championships, when the previous world record was broken by the 181 m harrach. athlete Pavel Ploc. During the next and recent years, the bridges were modified and currently the mammoth bridge – today the designation HS 185, allows flights over 210m. / an overview is in the History of Events at the World Championships 2002 /. when the previous world record was broken here in a flight of 181 m harrach. athlete Pavel Ploc. During the next and recent years, the bridges were modified and currently the mammoth bridge – today the designation HS 185, allows flights over 210m. / an overview is in the History of Events at the World Championships 2002 /. when the previous world record was broken here in a flight of 181 m harrach. athlete Pavel Ploc. During the next and recent years, the bridges were modified and currently the mammoth bridge – today the designation HS 185, allows flights over 210m. / an overview is in the History of Events at the World Championships 2002 /.
