The course
The course for 2026 is not yet ready. Below you will find a map of the course for 2025, further down you can find the map in both Google Maps, and GPX files for the courses of 10 km, 21.1 km and 42.2 km. The GPX files are for those of you who want to add the course to your watch.
The course for 2026 will be launched closer to the event.
Google maps
Here you will find maps of the routes from Oslo Marathon 2025 in Google Maps. Marathon participants run the half marathon route twice, and you will therefore find these routes on the same map.
The half marathon course has approximately 175 meters of elevation gain, and the marathon course has 350 meters of elevation gain.
For the 10 km trail there is approximately 50 meters of elevation gain.
GPX
If you want to add the course you are going to run to your watch, you can use the GPX files we post here. GPX files for marathons and half marathons coming soon!
