Change distance?

If you want to change the distance BEFORE we have assigned you a start number, you can send us an email at It is usually no problem to change to a shorter distance as long as we have available start numbers. It is usually possible to change to a longer distance by paying the difference between the registration fees, as long as we have available bibs.

If you want to change the distance AFTER we have assigned you a start number, you must first pick up your assigned start number, then refer you to the help desk in the start number distribution. Here you can change the distance if there are available start numbers.

On race day

Luggage storage

Restrooms and luggage storage are open from 14:00 to 18:30 at Kulturhuset. Luggage must be marked with the number tag on the start number before handing it in. The bib number is used as a receipt when handing in your luggage. It is not permitted to hand in large packages or luggage for storage.

Please note that long queues form in the baggage storage before the start, so we encourage runners to drop off their luggage/clothes in good time. Please note that luggage is delivered at your own risk, and we will not replace any luggage/valuables that are lost during the race. Clothes and items left in the start area will not be taken care of.

Required Equipment

Recommended clothing and shoes

The weather in January can vary a lot here north of the Arctic Circle. Everything from several degrees above zero to double-digit degrees below zero. Check or during the week to see what the weather will be like.

Recommended clothing

The temperature can vary a lot in January, and we recommend that you check or for an updated weather forecast as the race approaches. In general, the temperature is between 5 degrees plus and 15 degrees minus, and often around zero degrees. These are our recommendations for clothing and shoes based on the temperatures and conditions. Please note that this advice is based on local runners who are used to the weather, and if you're coming straight from a warm climate, you may need to dress warmer. These recommendations apply if you are running at medium to high intensity. Please note that lower intensity running will require more clothing.

0 - 5 degrees: Tights, wool socks, long sleeve technical shirt, windbreaker, buff, gloves, headband/hat 0 - -10 degrees: Tights, wool socks, wool underwear, long sleeve wool shirt, vest or singlet, windbreaker, buff, mittens, headband/hat -10 degrees and colder: Tights (some prefer a technical or wool layer underneath), wool socks, wool underwear, long sleeve wool shirt, vest or singlet, thin technical fleece jacket (if it is very cold or windy), windbreaker, buff, gloves, mittens, headband

Recommended shoes

Every year, the discussion at the City Hall is lively when the runners collect their start numbers - should you run with spiked shoes or without spikes? Follow us on social media for updates on conditions on the course the week before the race and on race day.

Ice: The most challenging conditions. We put sand on the ground, but if it's warm and icy, we recommend running with shoes with spikes or with stingers or chains.

Dry snow: Great conditions. Off-road shoes work very well in these conditions, otherwise road shoes with a more grippy sole work well.

Dry asphalt: It happened in 2019! Bring your Alpha Fly shoes with you!

The photos will be published on Facebook a few days after the race, as soon as we are up to date.
