Register for August 16, 2025 – lower price for early birds.

This is a different running event, where you and your friends can run the same day choosing four distances.  You can run 5.5 km around one lake, or the neighbouring lake at 10.5 km. Or four lakes, that makes it 21 km. All six lakes is a full marathon. You will run on both trails and small forest roads. Compared to most trail races our race is easy, compared to a most road race it is slightly more challenging. We expect about 1000 runners in total, about 300 for the marathon.

Run marathon in Sweden – forests and lakes

The location of the event, Fjällnora, is an isthmus between two of the lakes. Here you will find the most popular beach around Uppsala. So you can choose any distance – 5, 10, 21 or 42 km – and celebrate your finish with a well deserved swim in the lake.

Please note that this is a race for everybody, there are no prize money nor special service for elite runners.

The idea

It is more fun to run around something, and doing one lap. And what is more nice than running around a lake, and finish with a jump right in the blue? The lakes east of Uppsala make up for the magic combination of 5, 10, 21 and 42 kilometers.

One of our founders tried a six lake run last winter. The GPS stated 42,2 km. Not more, nor less than a full marathon! He had earlier noted that the distances around four lakes completed a half marathon. The too neighbouring lakes are just over a 10 km run and a 5 km run. At the center of the courses there the best beach in the area, with café, parking etc.

Environmental running

Running is a lovely way of enjoying nature – not spoiling it. So we keep our paths clean. Instead of disposable cups we will give you a multi-use cup, a Hydrapouch. T-shirts are optional and you will find a lot less merchandise, and much more experiences in our race.

Forest, lakes and a steam train

The shortest (5,5 km) is a beautiful forest run around the lake Ramsen. All other distances are mostly flat. Mainly on small roads through forest or rural areas. You will se a typical part of the region of Uppland, including glimpses of the lakes. You will see the century old summer houses of Marielund and cross the tracks of the steam train Lennakatten. But beware – the train is on duty, cross the tracks with care. Please find detailed course descriptions here.
