PolarNight Halfmarathon

Join an Arctic running experience in the Polar Night! Experience Norway’s largest winter race with approximately 2000 runners from all over the world. The PolarNight Halfmarathon takes place in the middle of the day, but at this time of year the sun never rises above the horizon. In the absence of the sun there will be darkness, occasionally interfered by the amazing display of colours that is so special for this time of year. Indeed, a trip to Tromsø to run the PolarNight Halfmarathon is also a great opportunity to hunt for the Northern lights (Aurora Borealis).

You can choose a distance after your level and ambitions: Marathon, Halfmarathon, Mørketidsmila (10K) or SATS Mørketidstrim (5K).

Be part of the very first PolarNight Marathon!

We are thrilled to announce that for 2021 the PolarNight races will include a full marathon distance! While our other races (Half-marathon, 10K and 5K) take place in the urban areas of Tromsø, the PolarNight Marathon will take runners to the secluded outer coastline, where it is truly dark.

This marathon is not for everyone. A cold and potentially severe climate makes everything much harder. For these reasons few special requirements are required to attend this race. This is no ordinary marathon. This is an adventure race.

If you’re looking for that wild and unique challenge for your bucket list, this is it.

On raceday

Where will I find my race results after I finish the race?

We use EQtiming system. The results from the half marathon distance and the 10k will be ranked. The 5k runners will see their own time on the result list, but the results are not ranked. We will post a link to the results on our website directly after the race.

What is the cut-off time for Polar Night Halfmarathon?

Max time limit for the halfmarathon distance is 3 hours.

How are the courses marked at Polar Night Halfmarathon?

There will be a kilometer marker for every 5km along the course. For the last 5km every kilometer will be indicated. There are race marshalls at every larger crossroads along the course. If the weather allows it, there will be burning torches along the trail.

Where can I store my bag during Polar Night Halfmarathon?

Bag storage for runners is available at City Hall (Rådhuset) from 14:30 – 18:00. Please tag your bag with the tag from your bib number before handing it in. Please hand in your bag early to avoid queuing before start. Bags/clothes are delivered at your own risk. We do not accept larger items of luggage. Please do not leave bags, clothing or other items  in the starting area or elsewhere (besides designated bag storage), since such items are likely to disappear. The organizers can not be held accountable for any such loss.

Where can I find toilets at the Polar Night Halfmarathon?

Toilets are only available at the start- and finish area. No toilet facilities during the race.

Are there any service stations at the Polar Night Halfmarathon?

There will be drinking stations every 5 km of the race, and at the finish. Water and Maxim Sportdrink will be served at all the service stations. Toilets are only available at the starting- and finish area.

What should I wear when running the Polar Night Halfmarathon?

The weather can vary quite a bit above the arctic circle in January. Anything from a few degrees plus to some minus degrees. The good thing is that running keeps you warm! We advise runners to layer up their clothing after the temperatures and weather. If it is windy or temperatures below zero we prefer these type of clothes for winter running:

Winter tights or windbreaker pants, thin woollen longjohns or thin woollen shorts, thin woollen socks, woollen shirt, windbreaker jacket, an extra thin vest if you get cold very easily, something to cover my neck, headband/hat, and thin woolen gloves. Every year there is a big discussion at city hall when the runners pick-up their bibs- shoes with spikes or no spikes? Some years only parts of the course are covered with ice or snow, making it extra difficult to decide.

As with everything else this comes down to your experience with running in these conditions and temperatures, as well as your own preferences when it comes to race clothing. Also, do a short test run on race day or the day before to try out the conditions. That might answer you questions both about clothes and shoes with or without spikes.

After the race

Where can I find the results from Polar Night Halfmarathon?

Will I receive a medal for my race?

All finishers receive a medal at the finish line.
