International Skyrunning Federation



Following an in-depth analysis, the ISF has developed a new system to identify and award skyrunning races with a label. After the successful launch in 2018 of the Qualified Race/Course labels, the new system is split into two distinct sections: “Certified Course” and “Qualified Race”.


Skyrunning and Vertical Kilometer® race organisers can request the Certified Course Label.

The label is awarded to courses compliant with ISF definitions. A number of parameters, together with the GPX data are evaluated and an exclusive algorithm is applied.

Essential factors for Course Certification

  • Average incline
  • Altitude
  • Distance
  • Terrain
  • Uphill section
  • Vertical climb


  • Organiser supplies online form
  • Organiser provides GPX course profile, photo and/or video
  • ISF elaborates GPX track analysis elaborated with dedicated algorithm
  • ISF analyses the technical level of the course and rules

Races that receive ISF approval and pay the designated fee will receive the Certified Course (CC) Label and will be included in the annual list published on www.skyrunning.com. Races that don’t meet the minimum requirements will not be included.
