All the Fjällmaraton feels condensed into 12K: Ottsjö 12K offers a gorgeous, memorable mini-mountain marathon on the same day as its bigger siblings: Salomon 27K or the Kia 45K.

But at 12 kilometres with 300 metres of climbing, Ottsjö is still no walk in the park—it’s a great challenge for short distance runners, newer trail runners, those returning to the sport, or those who are building up to our bigger distances.

Starting in Ottsjö, you’ll head up Petterfjället and past Klapphögarnas wind shelter before the flat trail across Platåkåtan. From here, you’ll drop down, join some beautiful single track and trace the edge of the lake back to where you started.

Run with your kids

Now a popular aspect of this race, we introduced the opportunity for kids aged 10-13 to participate alongside an adult for just 200kr.

The minimum age for entry remains 14 if running independently. Note that 14–18 year olds can enter for half the price of an adult.
