What is
skyrunning

Skyrunning is running in high-mountain terrain under the rules of the International Skyrunning Federation (ISF). Its disciplines are defined by distance and elevation gain - among them VERTICAL, SKY and SKYULTRA, the three disciplines of the 2026 Skyrunning World Championships on La Gomera.

In Poland, skyrunning centres around the Tatras, Karkonosze and Beskids.

Skyrunning is not just running - it's climbing, technical agility and a fight against lack of oxygen. A sport that redefines the limits of the human body in the most harsh environment on the planet.
