Official event pageWhat this race demands
This half marathon trail running event requires sustained aerobic output and technical footwork over a rolling spring course.
Aerobic endurance
Covering the 21.1 km half marathon distance demands consistent cardiovascular pacing from start to finish.
Trail durability
Navigating the forested terrain of Boserup Skov and the shores of Roskilde Fjord requires resilience against uneven footing and sharp changes in gradient.
Climbing economy
The 200 meters of elevation gain requires efficient climbing mechanics to maintain forward momentum without excessive muscular fatigue.
A target intake of 30 to 60 grams of carbohydrates per hour is recommended to sustain energy levels across the half marathon duration.
