As of March 2017, the longest jump ever recorded in any official competition is 253.5 metres (832 ft), set by Stefan Kraft at Vikersundbakken in Vikersund, Norway.
On 23–24 April 2024, Ryōyū Kobayashi made four successful attempts to unofficially break the world record on a temporary ski flying hill at Hlíðarfjall in Akureyri, Iceland.
This artificial small hill was built at Lekum gård (farm), a few hundred metres away from Eidsberg church.
Tim Ashburn says in his book The History of Ski Jumping that Norheim's longest jump on the circular track in Haugli ground in 1868 should have been measured at 9.4 metres alen[8] but that newspapers in Christiania reported that the length "was a little exaggerated", so the official record is everywhere written as 19.5 m. The sport quickly spread to Finland, the United States and Canada, where some of the subsequent records were set.
[14] The distance of a ski jump is measured from the end of the 'table' (the very tip of the 'inrun' ramp) to halfway between the athletes' feet when they touch ground.
To qualify, the jump must be made in a sanctioned competition, or official trial or qualification runs for these, with a system to control the actual length.
However, if an athlete touches the snow with any part of their body after landing, and receives style points greater than 14 from at least three judges, the jump is valid and counts as an official world record.
[16] Progress of all valid world records by fully standing on both feet, although International Ski Federation doesn't recognize them.
Those jumps were never actually world record distances, false claimed by some stats and media: Not counting if touching the ground, falling before reaching the outrun line or landing during non-competition training rounds.
