AUGUST 21–23, 2026
Tromsø mountain challenge
Trail running in beautiful Norwegian nature
Three days of raw nature experience and true running joy – when nature is at its most colorful. Varied trails through the Arctic landscape give you an unusual challenge, and views you will never forget.


From mountain peaks to plateaus
An arctic running adventure that provides real running joy and raw nature experiences. The trails vary from challenging trails up the Sherpa stairs in Explo Ekstremløpet and Explo Ekstremstafett , to the Ultra and Half-Ultra races over mountains and plateaus, as well as Dalheim Rundt in more family-friendly surroundings. Several of the races end with a spectacular descent through beautiful Tromsdalen and the finish at TUIL Arena.
This weekend is always held at the end of summer, when the air is fresh and Northern Norway shines in its most beautiful autumn colors!
Running across spectacular mountains and plateaus is an experience in itself – both for new participants and for experienced runners who know the terrain well. The nature and the challenge mean that many return year after year. The trails also offer demanding sections that really test both strength and endurance.
