Sweden's Jesper Tjader set the new record in Are this morning, sliding 154.9m (508ft).
The 28-year-old from Östersund revealed: "I have done a lot of tricks on rails before, but never near such a long rail as this. I felt like that would be a good mission to have, and when Tom Wallisch set the record it looked insane to me. So I thought, 'I have to try and do that'."
Earlier in May, work began at Stendalen in Åre, Sweden, to build and implement the world's longest rail with the just over 162 metres (531 feet) long metal rail eventually put in place for Tjäder.
It took him three days and 127 attempts to land the new Guinness World Record of 154.49 metres (506 feet, 10.28 inches) on May 9 at 5:23pm CEST as he jumped on the rail at a speed of about 77 kilometres per hour (47.85 mph) and landed with the leading ski on the rail eight metres in.
Tjäder added: "Being the official Guinness World Record holder feels pretty cool. I have dreamt about it since I was a kid. This rail was a hard challenge, and my guess was that it would take about 525 attempts, but it went way easier than I expected."
