International Skyrunning Federation



The International Skyrunning Federation has developed a label to recognize races with an official “stamp of approval”. The project, aimed at strongly identifying the characteristics of the sport, was approved at the General Assembly in 2017.

Various factors are taken into consideration, from the basic parameters of distance, vertical climb, altitude, etc to the quality of the field, the finishing time as well as a specially developed algorithm. Ratings are from 0 to a maximum of 5. These factors are essentials for the first step: ISF Qualified Course. Races that don’t meet the minimum requirements will not be included.

Races already approved as ISF Championships and internatinal circuits, considering the global value in term of organisation and athletes participation will be ISF Qualified Races.



Main factors taken into account:

  • Race conforms to ISF parameters (see ISF Rules)
  • Course parameters (average incline, climb, peak reach, altitude, snow/glacier)
  • Athletes’ participation (number, finishing times, nations, etc)


  • Overall evaluation calculated with dedicated algorithm
  • Course evaluation & GPS track analysis by ISF Referee
  • Technical level evaluation


  • Inclusion in the list of official ISF Qualified Races on www.skyrunning.com
  • Use of ISF Qualified Race/Course logo on the race website
  • An ISF Qualified Course automatically has the faculty to bid for World Championships, Continental Championships, Youth World Championships, Skyrunner® National Series or Skyrunner® World Series races
  • Inclusion in future ISF Global Ranking which will take into account all ISF Qualified Races

Label costs:

  • €300 flat entry fee
  • €200 for races (*) approved by ISF Referee
  • €200 annual fee to maintain this status and benefits
  • This fee does not include eventual fees to the National Member

(*) Skyrunner® World Series & ISF Championships
