Between 2015 and 2017, upgrades from K185 to K200 were also completed in Kulm, Planica, and Oberstdorf. In 2018, the hill sizes on all active flying hills were upgraded to 235–240 m, making them fully equipped for jumps exceeding those distances (previous hill records were broken at each opening event), as well as having improved facilities for athletes and spectators. Harrachov remains the only hill, at K185, to have not been upgraded in any major way since the 1990s. Although the new hills are much larger than ever before, they generally feature longer and less steeply angled slopes, designed purely for the V-style and with the knowledge of 80 years' worth of world record progression.
