The trail maps were updated on May 20th.

The trail maps and GPX for all distances were updated on May 20. There was a small detail on Bygdøy that was corrected.

21km and Walk21km had a major error along the Lysakerelva River, but are now correct.

It is also now possible to download gpx outside of Strava.

Please note that there may be changes leading up to the race, so check here on the website if any changes to the course are announced.

Otherwise: The course is marked with signs and/or field flags only at all intersections. Where it is not possible to run wrong/no other way to run, it is not marked until the next intersection. This means that in some places you may experience running longer stretches without markings until the next intersection.

Familiarize yourself with the trail – there’s no guarantee that someone will remove a sign just to be naughty. We hope not!

But enjoy the map – and also read other practical information.

When you are prepared you will have a much better experience on race day!
