Hafnarfjall Ultra is a trail run event first held on June 28 2025 in the steep slopes of Mt. Hafnarfjall close to Borgarnes town on the west coast of Iceland. The event consists of four races, three of which are highly technical with relatively high elevation compared to the distances.
This run is especially designed for families of all ages and other people who do not feel like running to the top and back. The race starts at a refreshment station on the gravel road at the foot of Hafnarfjall. From there, the route goes up the gravel road towards the mountain, and then follows a hiking path up to “The Stone” of Hafnarfjall. At that point, the runners turn right and follow another hiking path down to the gravel road, all the way to the finish lie at the refreshment station.
