Not for the faint-hearted this one, as competitors strap on a pair of skis, start off down a hill and then shoot off into the ski from a ramp at the bottom.
Then they have to travel as far as they can, look good while doing it, and land - not only in one piece, but also as gracefully as possible.
Points are earned for distance travelled and a series of judges award marks for style too.
There are two lengths of ramp to leap from. One is 90m-long and another a mammoth 120m-long, with jumps as far as 140m and beyond sometimes.
There is also an event called the Nordic combined, where athletes take part in a ski jump before embarking on a cross country ski.
Points won in the ski jump are converted into times to decide the starting positions for the race section.
