CPH–OSL Road is a self-supported ultra-distance road race that takes riders from Copenhagen to Oslo, linking the best of Denmark, Sweden, and Norway in one unforgettable Nordic adventure. As the third chapter of the Nordic Chase series, it combines fast roads, scenic coastlines, dense forests, and rolling Scandinavian terrain under the endless daylight of the Nordic summer.
The route covers approximately 730 kilometres with around 5,200 metres of elevation gain, starting in Copenhagen, Denmark, and finishing at Vippetangkaia, Oslo, Norway. Riders follow a fixed GPX route through the Danish countryside before crossing by ferry from Helsingør to Helsingborg. From there, the course heads north through Sweden’s forests, lakes, fishing villages, and quiet coastal roads before crossing into Norway for the final approach to Oslo.
CPH–OSL Road follows a strict self-supported philosophy. Riders are responsible for their own navigation, food, accommodation, and mechanical repairs, with no outside assistance permitted. The event has a 103-hour time limit, rewarding efficient pacing and smart decision-making while remaining accessible to both experienced ultra racers and first-time long-distance riders.
With smooth roads, spectacular Nordic scenery, and an international point-to-point format, CPH–OSL Road offers a unique road ultra experience. From Denmark’s coastal landscapes to Sweden’s endless forests and Norway’s dramatic approach to Oslo, it is an unforgettable journey through the heart of Scandinavia.
