Natural tracks are partly built on existing paths, but also on specially created areas and must of course be adapted to the given terrain.
They are delimited with wooden bands, plastic walls or foam mats and only prepared with snow and water (ice).
From the 2015–16 season there are trial runs (city event in Moscow, Junior World Cup Seiseralm) and parallel competitions in ski areas (for example in Kühtai / Tyrol and on the Seiseralm / Italy).
In addition there are runs in Russia, Poland, Romania, Bulgaria, Finland, Sweden, Norway, the Czech Republic, Turkey, Croatia, New Zealand, Slovenia, Ukraine, Slovakia, Switzerland, France, and Liechtenstein as well as Canada and the United States.
