Kroppefjäll Trailrun is a headlamp trail race held at night through the forests and hills of Kroppefjäll in Västra Götaland, Sweden. A reflective vest is required, making the race as much about navigating the dark as it is about covering distance. The main options include 42 km for experienced trail runners, 21 km for pairs, and shorter distances for those seeking a less demanding challenge.
The long course ventures deep into Kroppefjäll, combining rough singletrack and off-trail terrain with gravel and forest roads. The 21 km route includes approximately 400 meters of elevation gain and begins at Skidstugan on Granan, concluding at Kroppefjäll B&B in Dals Rostock. Past race accounts mention snowy woods, standing water, and significant mud, consistent with an event focused on darkness, uneven terrain, and teams supporting each other's progress.
