Oslo, Norway · Saturday 16 September 2023
Running through Oslo offers a rare chance to experience one of Europe's most livable capitals on foot. The Norwegian capital sits at the head of the Oslofjord, surrounded by forests and water, and the city itself has managed to stay remarkably human-scaled despite being a major Nordic hub. You get genuine urban running, past historic neighborhoods and along the waterfront, without the suffocating density of larger European marathons. The course takes you through the actual city that Norwegians live in rather than just past monuments, which makes the experience feel grounded rather than ceremonial. The DNB Oslo Marathon keeps things straightforward with a flat to gently rolling route that rarely gets steep. Total elevation gain sits at just 142 meters across the full distance, making it a course where your fitness matters more than your hill strength. You'll climb gradually from sea level up to about 73 meters at the highest point, then settle back down. This terrain profile works well for runners chasing times without wanting to fight constant inclines, and the rolling nature keeps things from feeling monotonously flat. With over 25,000 participants, the race has the energy of a major event while still maintaining the character of a Scandinavian gathering. September weather in Oslo can be variable, but autumn conditions typically favor distance running. The course winds through the city streets rather than purely trail terrain despite being marketed as such, giving you the social atmosphere of a big city marathon without losing the sense of actually running through Oslo itself.

BMW Oslo Marathon is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
Our difficulty rating for BMW Oslo Marathon is calculated using a model that combines elevation gain, temperature impact, and surface type. Use the difficulty calculator above to enter your target finish time and see exactly how many minutes this course would add or subtract compared to a perfectly flat, cool, road-based marathon. Faster runners and slower runners are affected differently by the same course conditions, so the difficulty is personalised to your pace.
