Tröllið - 43 km


Tröllið (43 km) is a trail race with an elevation gain of 1870 meters where you run up to the mountain Súlur and from there along the mountain ridge into Glerárdalur. It is a challenging route in spectacular nature.



The race starts in Kjarnaskógur, from where you run up to the rocks nestled above the forest, enjoying a great view of the town and the fjord. After ca. 300 m of ascent, you´ll pass Gamli, an old scout lodge and then continue over the claps to pass another scout lodge called Fálkafell. From there, run down to the Sulur parking lot, where you´ll find the first drink station.

Continue to the first real ascent of mountain Súlur. After over 5 km and 900 m of ascent, the top is reached. From there you will continue to Syðri Súlur and then south along the mountain range, past Krummi and to Litli Krummi, but then we turn down into Lambárdal, over Lambárjökull and up to Lambáröxl. From there down to Glerárdalur to the Lambi hiking lodge. This part of the route is rocky and steep in parts, and we recommend that you proceed with caution. At Lambi there is a drinking station run by the local rescue team.

From Lambi, you follow the trail 11 km back to Sulur parking lot. The path from there crosses a small canyon and then follows the path along the river Glerá. Cross Hlíðarbraut (road) and continue along Glerá to the University of Akureyri. The race finishes with a 2-3 km run along the streets of Akureyri into the center of town.  

Competitors in Tröllið must have a track of the route in a watch or phone.
