10.3 km – run around lake Trehörningen
You will get a little of everything in this race. It’s easy to run – small gravel roads, some nice forest paths and one crossing on a temporary bridge. You will see forests along the way and the beautiful summer villas of Marielund, and with some luck – a steam train passing by. There are three service stations, and the course is well marked. After finish, you are welcome to take a swim in of the lakes!

All distances – the marathon, half marathon, 10k and 5k start and finish in Fjällnora by the lake Trehörningen, on the same day. The 10.5 km race starts at 11 AM, which is 30 minutes after the half marathon and 30 minutes before the 5k. So if you have friends running other distances, they don’t need to wait long.
Start: 11:00 AM
Elevation: Don’t worry, there are no mountains in this part of Sweden. The course is mostly flat (from 20 to 50 m above sea level) – however at the end there are some lower hills up to 20 meters in height, which can feel tough when you are tired.
Find your way: All courses are well marked and there is no need for a map or remembering the route. You will follow blue ribbons and signs. Just avoid the half marathon (red) and marathon (yellow) and you will be fine. These description is just here for those of you who are more curious than others.
Equipment: Ordinary running shoes will be fine. Bring a free multi use cup or you own mug or bottle.
These 10 km will move you around lake Trehörningen counter clockwise. Then name “Trehörningen” means “Three horns”. You will actually see three lakes: Along the route you will get a glimpse of lake Gårsjön and finally, just before finish you will cross a temporary bridge between Trehörningen and Ramsen.
Starting north you will have an easy run on a pleasant forest trail. After 1 km you will run a few hundred meters on the Fjällnora-road. You continue on a path parallel to this road (actually the old Fjällnora road) and soon you will see the beautiful holiday houses around the lake. We usually put up a small aid station at Selknä, just in front of a lovely pink house.
Please note that you will cross the railroad after about 3 km. The train is slow needs a long breaking distance, so please have all respect. Don’t run in front of the train!
At the train stop Lövstahagen you will find another aid station and a view of lake Trehörningen. Next is a lovely stretch through the village of Marielund, with 100-year old holiday houses. You will cross the train tracks once again by the small station house, so take care! There is a WC in the small café there.
Continue from the lovely train station on the asphalt road less than one km before turning left. (The marathon and half marathon continue straight on, so watch the signs…).
The next few km will go through a forest, but you will catch a glimpse om lake Gårsjön on your right. Continue until the next aid station, Häggdal. Here the marathon and half marathon runners will join again.
You will catch a glimpse or two of Trehörningen on your left side as you continue along gravel roads, mostly through forests. At one point your turn left on a meadow towards the lake. This is a new path for 2025.
Now the adventure starts. The paths are sometimes tricky with stones and roots, so please take care. It might be tiring and most people will have to slow down and walk up the short hills. We have constructed two footbridges for your convenience.
After the second footbridge you will meet the 5 km-runners. We have arranged a temporary bridge in the strait between lakes Trehörningen and Ramsen. You will hear the sounds of Fjällnora and soon you will pass the café and rush to finish and pick upp your well deserved medal!.
