Inrun of Olympic ski jump at Calgary modernized

on 2013-11-19

A profound modernization of the inrun of K89 normal hill of the 1988 Winter Games at Calgary was carried out during summer months.

Canada Olympic Park with its two Olympic jumping hills was developed for the Olympic Winter Games at Calgary in 1988. While the large hill K114 has been sharing the fate of so many Olympic hills and has not been used for several years, the K89 normal hill together with the smaller plastic covered hills is building the most important training center of Canadian ski jumpers. In order to strengthen this status the inrun of HS 95 has just been modernized.

After the last modernization of the 1986 completed, plastic covered K89 hill was carried out in 2005, now a profound renovation of the inrun was carried out for around 70,000 Euro in cooperation of operator WinSport Canada and Altius Nordic Ski Club. Main goals were to correct age issues and make the hill ready for the future needs.

In order to increase inrun speeds and lower the flight path for over-coming the typical side and tail-wind, the take-off angle was elevated to 10.75 degrees and made 6.0 m long. For a lower compression the inrun transistion curve was modified. Furthermore the force-plate system installed in 1990's was reactivated in order to provide immediate feedback for training jumps.

A new cooling system for the ice track in winter was also installed in order to reduce maintenance costs and maintain reliability of training sessions and competitions. With a renewed FIS homologation international ski jumping could return back to Canada.

What has become of the jumps at Big Thunder in Thunder Bay Canada? I took many jumps there years ago and have wondered why it seems to be out of commission since the World Championships in 1995.
