Vikersundbakken or Vikersund Hill〔MacArthur, Paul J. 2011. Taking Flight. ''Skiing Heritage'' 23(2) (March-April): 20–25, p. 23.〕〔Bass, Howard. 1968. ''Winter Sports''. South Brunswick, NJ: A. S. Barnes, p. 62.〕〔(Ski Jump: Watch Anders Fannemel Set the New World Record. 2015. ''The Telegraph'' (February 16). )〕 is a ski flying hill at Vikersund in Modum, Norway. It is the largest in the world. Seven world records have been set on the hill, with the current of 251.5 meters being set by Anders Fannemel.〔http://www.aftenposten.no/100Sport/hopp/Prevc-hoppet-250-meter-og-smadret-verdensrekorden-492019_1.snd (Norwegian)〕 The complex also consists of a large hill, a normal hill and several training hills. The hill opened in 1936 as a large hill. It was rebuilt to become a ski flying hill in 1964 and has later been converted in 1989, 1999 and 2010. The large hill was built in 1988. The hill was the first to receive floodlights in 2006. It has hosted the FIS Ski Flying World Championships four times, in 1977, 1990, 2000, 2012. ==History== thumb In 1894, Vikersund SK was established and started with ski jumping. Until the 1930s, they used six different ski jumping hills around the area. By then, the club had fostered sufficiently good jumpers that it was proposed to build a proper hill. A committee was established on 19 March 1935 and led by Gustav N. Hovde. At first they found a suitable location north of Heggen. However, they failed to reach an agreement with the land owner. Instead, Hovde proposed using the steep hill close to Heggen Church. After purchasing the land, construction started later in 1935. The original hill was designed by Thunold Hansen. Construction cost 6,290 Norwegian krone (NOK), of which NOK 1000 was borrowed and the rest of financed through private donations.〔Drolsum: 42〕 The first hill had a length from the top of the in-run to the bottom of the out-run of and an elevation difference of . The in-run was long and had an elevation difference of .〔 The hill was inaugurated on 29 January 1936 with a 50-meter jump by Birger Henriksen. The longest jump on the opening day was made by Reidar Andersen, who jumped 86 meters. At the most he was above the landing slope, so the take-off was lowered from 6 to 11 degrees.〔Drolsum: 43〕 The main logistical issue with the events was the poor transport service, with only a narrow road to the hill. During the 1950s, the attendance rose well beyond the former 5,000, forcing the road to upgraded in 1955.〔Drolsum: 47〕 By the 1950s, ski jumps were being built larger and in 1954, Kristian Hovde proposed to expand Vikersundbakken, which he hoped would allow jumps of . The plans were passed by the club's annual meeting on 13 September, with construction starting in the summer of 1955. The lower part of the landing slope was dug down , the in-run was raised up to and a new jury tower and stairway was built. Additional expansion was passed on 27 April 1956: a tall scaffolding in-run was built on top of the old in-run. The hill was designed by Carl Borgen. Contractors were Brødrene Teigen and since the club did not have sufficient funds, they were willing to wait with the payment until they had. The new hill was inaugurated on 10 March 1956.〔Drolsum: 46〕 The new hill was too large to be regarded as a large hill, but was not large enough to be categorized as a ski flying hill. In 1964, the club appointed a committee led by Ottar Grøtterud to consider an expansion of the hill.〔Drolsum: 49〕 There was only to be built one ski flying hill in the Nordic Countries, with the main alternative being Renabakken in Rena.〔Drolsum: 54〕 Construction cost NOK 445,000 and was in part financed with a NOK 75,000 grant and NOK 150,000 loan from Modum Municipality, NOK 20,000 from volunteer work, NOK 80,000 from the club, grants from companies and banks and from Buskerud County Municipality, and NOK 100,000 in betting funds.〔Drolsum: 55〕 Construction was done by Entreprenør Gunnar Sterkebye. The hill received a new tall in-run and a new jury tower form the jump. On the landing slope and out-run, of earthwork had to be moved. Work was made more difficult because of high snowfall and temperatures down to . The hill was inaugurated on 13 March 1966.〔Drolsum: 53〕 The next upgrade of the venue were minor upgrades ahead of the 1977 World Championships.〔 Ahead of the 1990 World Championships, the venue was again renovated. However, to secure better recruitment, the venue also received a new normal hill with a K point of K-90.〔Drolsum: 61〕 The hill was rebuilt for the 2012 Ski Flying World Championships. It was the first in the world with a hill size of 225 meters, making Vikersundbakken the largest ski flying hill in the world at the time. It has been built further into the terrain with sidewalls made of natural gravel to avoid wind problems during competitions. Furthermore, it has been slanted slightly to the south from the inrun area to further reduce wind problems. The hill was ready for the 2011 Trial Ski Flying World Championships held on 11–13 February 2011. The old inrun was demolished in 2010. Architects of the new and larger hill were Slovenians Janez Gorišek and his son Sebastjan. Janez, together with his brother Lado, is most famous for creating Letalnica Bratov Gorišek in Planica, previously the largest hill in the world at HS 215, before Vikersundbakken was reprofiled and enlarged in 2011. Janez is usually named as the 'father' of modern ski flying and is also known as an expert on ski flying hills. At the trial ski flying championship, Johan Remen Evensen jumped 243 meters to set a new world record during the first official training on 11 February 2011. Later, during qualification, Evensen improved the world record to 246.5 meters. During autumn 2011 the hill was further improved with a different radius at HS 225, increasing the ability to stand on greater lengths. Additionally the jump itself was cut a meter short because of decreased inrun speed needed by the jumpers. During the 2011 event, it was deemed necessary to add several inrun gates the hill below gate 1 due to better conditions not anticipated by the organisers during construction in 2010. A total of five gates were added. Gregor Schlierenzauer praised the hill during interviews, calling it the best hill in the world. Evensen was also extremely satisfied with the hill, calling it "perfect". The K point was increased from K-195 in 2012 to K-200 in time for the 2015 event,〔("Vikersundbakken now a K200" ). skisprungschanzen.com. Retrieved 2015-03-09.〕 resulting in two new world records on the same weekend: Peter Prevc jumped 250 m (820 ft) and became to first to ever surpass the 250 m mark, and this was followed by Anders Fannemel with 251.5 m (825 ft) the next day. In a training round prior to Fannemel's jump, Dimitry Vassiliev jumped 254 m (833 ft) but fell hard upon landing, rendered his jump invalid as a world record. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vikersundbakken」の詳細全文を読む スポンサード リンク
