Trail 31 km

31 km
MAX 800

If you take a close look at the profile for the 31 km course, you will hopefully get an idea about taking it easy from start. The first 3 km from Sørkedalen is pretty tough. After climbing the first kilometeters on gravel road you will enter technical paths. After 10 k you´ll find the only service station with food for the 31 km, before you continue by the pretty lake Bogstadvannet and down by the beautiful Lysaker river. The last 10 k has about 6.5 km asphalt, and where you can feel the breeze from the Oslo fjord.


If you pass these stations after they are closed, you are still timed. The registration mats are located at all support stations and other places.

The most important thing is that you reach the finish line by 8PM.
Should you have a bad day and arrive after 8PM, you will still get your time registrated - but we must start to rig down the finisher area no later than 8PM.
Support station Fossum (same area as 21km start) closing 5:30PM
Water station Thaugland - for all distances - closing 7PM
Bygdøy - last intermediate for all distancesr (approx 7 km before finish) closing 7:30 PM
Finish: 8PM
SUPPORT: Within the support stations only.
