Clothing

Please note: Shoe spikes are mandatory for running on the ice. 

Proper clothing is mandatory during the Polar Circle Marathon and Half Marathon. Failure to dress properly and follow the guidelines from the medical team and race officials means disqualification. The medical team and race officials always have the right to stop and take out a runner who is not dressed properly for the weather. All participants must follow the below guidelines and make sure it’s possible to cover all skin.
Shoe spikes, hat and gloves, and all-around wind protection is absolutely necessary during this race. Cotton clothing is a total NO-GO! 

Layers are key to a good race and to keeping you as dry and warm as possible. You need to be prepared for changing weather. It is always better to start out in a layer too much than one too little. Remember: it is easy to cool off if too warm, but hard to get warm if too cold.

How many layers you wear is an individual matter and weather dependent, but a minimum of 3 layers is recommended.

There are personal supply stations along the course where you can pick up dry and warm clothing – see “Supplies on Route." Wet and cold items can be dropped at any water station along the course.

We do not give specific recommendations on products, but have named some of the brands available in active polar clothing that we know have a good and well-tested product.

Base/Inner Layer (sweat transporting layer):

Must be a functional thinner layer that transports sweat away from your body (called moisture-wicking) and dries fast. Make sure it’s comfortable to wear and doesn’t restrict you in your movements.

Avoid base layers with zippers that touch the skin. Any product with Merino wool ensures extra protection.

Check out: Craft, Peak Perfomance, Falke, Under Armour, Icebreaker, Salomon, Helly Hansen

Mid Layer (insulating layer):

Should be a loose weave fabric or fleece with additional thermal insulation thicker than your base layer. Again it’s important that it doesn’t restrict your movements, especially with the outer layer on top.

The mid layer should provide warmth and breathability. Again it’s important that moisture is transported to the outside/next layer. Some mid layers even have wind protection, but this is not a must as you won’t be running without your top layer when windy. 

Check out: Craft, Montane, Icebreaker, Salomon, Newline

Top/Outer Layer (weather-protective layer):

The top layer can be divided into two categories: Soft shell and hard shell. Regardless of what you choose, wind protection is the most important thing. Water resistance is a benefit too in case it snows.

While soft shells are now being manufactured with better wind and water resistancy they’re still not as efficient as a hard shell. The hard shell on the other hand, does not have the same breathability as the soft shell, although development of vent zones does allow for more airflow and thus minimize the risk of wet and cold mid- and base layers.

In extreme wind conditions starting in both a soft and a hard shell can be advisable, but it is also very likely that you will soon be too warm and will need to drop one of them.

Check out: Craft, Montane, North Face, Peak Performance, Salomon, Helly Hansen

Remember: Cotton is your worst enemy when running in an arctic climate. Cotton retains water and will make you very cold, as well as rub your skin raw. Do not wear cotton clothing during the Polar Circle Marathon and Half Marathon. High-performance clothing will also decrease your chances of getting blisters and calluses. Merino wool is a potential option, as wool will keep you warm even when it's wet. Brand such as Icebreaker and Smartwool make perfomance-wool clothing. 

Legs:

Three layers on your legs are likely to be too much. The top layer on your legs must have wind protection and preferably thermal functionality. A base layer under a winter tight will work if the tight has wind protection. Alternatively a normal winter running tight may work fine as base layer under a pair of windproof running pants.

Running without wind protection on your legs may cause frostbite on knees, thighs and other lower body parts.

Check out: Craft, Montane, Patagonia, Salomon, Newline

Gloves:

Again, wind protection is the most essential, but of course your gloves should be warm too!
Make sure your gloves aren’t too tight around your hands and fingers – it’s better for airflow between your skin and the fabric. Layers will be an advantage in very windy conditions with inner gloves (liners) under a warmer and looser pair of outer gloves or mittens.

Hand warmers are an option, but as we try to leave as little a footprint as possible on our race site we recommend the reusable solutions over the disposable versions.

Extra gloves can be placed at one or more of the personal supply stations, as especially the inner gloves tend to get wet.

Check out: Craft, Montane, North Face, Icebreaker, Salomon, Hestra

Head and neck:

A winter hat is an absolute must. It should cover your ears too. Some prefer a functional moisture wicking hat while others opt for warmer traditional winter hats. A hat of 100% wool will have both features, but may be itchy for some people.

The neck should be covered with a scarf or a neck tube/buff. It’s important that the scarf/buff can be drawn up over the mouth and nose in case of strong winds. However, running with your nose and mouth covered for a longer time will cause condensation and make your face more prone to frostbite.

Balaclavas and buffs with air holes for mouth and nose are available, but even these will eventually turn in to an ice mask. If windy and necessary to cover your face make sure you actively remove the ice building up on your cover. A spare scarf/buff at the personal supply station is advisable. Star Wars fans may invest in a ColdAvenger. 

The use of tape on cheek and nose is not recommended. There’s no evidence that this will prevent frostbites, but it will definitely prevent the medical team from seeing signs of frostbite.

Sunglasses or light ski goggles will be a relief in sunny, windy, and/or snowy conditions.

Feet:

Your feet are the least exposed part of your body as you’ll be constantly moving sending a lot of blood to your feet and toes. We do recommend, however, that you wear warm running socks, potentially with a thin liner sock underneath. Make sure the sock is high so there’s no open skin gap between sock and tights/pants. A spare pair of socks at the personal supply station is advisable.

If the ice sheet is covered in a thick layer of snow gaiters will keep it out of your shoes, but cheaper solutions like a plastic bags inside your shoe may do the trick. If you’re prone to blisters the plastic bag may cause too much friction.

Change of clothes:

Half marathon runners and marathon runners staying at the Old Camp should pack a small bag with extra clothes to be available at the finish line. Marathon runners at Hotel Kangerlussuaq and Polar Lodge can walk to their rooms and do not need to prepare a change of clothes.

Make sure you mark all your clothes and items with your name and/or bib number for easy identification. Clothes and items dropped at the water stations during the run will be taken back to the finish area at the end of the race. The race organisers cannot be held responsible for any lost or damaged items left along the route.

Route & Elevation

Route Map

Elevation Map

Route Description

The Polar Circle Marathon route consists of frozen tundra, uneven gravel roads and the Greenland ice sheet, with parts of the route covered with snow depending on the weather.

Route Logistics

The race starts near the ice sheet and includes a loop on the ice—approximately 3 km, with the exact distance confirmed shortly before race day. 

Kilometer markers are placed along the route but may be a few meters from the exact location. On the ice, the route is marked with poles and flags. Due to the risk of hidden crevasses, runners must stay on the marked route at all times.

Water stations are located about every 5 km, offering water and warm electrolyte drinks. Personal supply depots can be dropped off at the start area for 10, 21, and 30 km (10 km only for the half marathon). Bring your own gels and snacks, as these are not available for purchase in Greenland.

There are no toilets on the route, but toilet paper is provided at all water stations. Please carry out all trash, as waste does not decompose in the freezing temperatures.

Safety Precautions & Medical Team
Race Precautions

A medical team is ready in case of injury or severe exhaustion. A doctor will be present on the ice sheet as long as runners are on it. A doctor will be patrolling the route and a doctor will stand by in the finish area.

A sweeper will follow behind the last runner throughout the race.

A bus will be parked just before the entry/exit to the ice cap, ready to warm up runners if necessary.

In case of strong winds all runners will be stopped before entering and after exiting the ice cap and checked for signs of frostbite.

Runners who wish to drop out of the marathon should go to the nearest drink station where sleeping bags will be available to keep you warm. Transport to the finish area will be arranged for all runners who leave the race, but please be aware that waiting time may occur.

Take extra precaution when running on the ice sheet. Fall injuries on the hard ice could mean your race is over.

Frostbite

Frostbite is a risk at the Polar Circle Marathon, but will cause no severe injury if treated correctly and in time. There are 3 degrees of frostbite to describe the duration and depth of the injury:

1) First degree frostbite signs are sensations of cold and pain and/or the affected skin turning white. First degree frostbite is only a superficial injury and can be treated by anyone, including yourself, simply by warming/thawing up the affected part of your body. If it’s not possible to go inside warm hands can thaw the frostbite, but remember to take off gloves and warm skin to skin. If your fingers are at risk they can be warmed against your stomach or in the armpits.
After thawing first degree frostbite the skin will be slightly red and may still feel “buzzy”, but as the blood is now streaming back it takes longer time for the same area to get frostbitten again. Eventually all signs of a first degree frostbite will disappear.

2) Second degree frostbite is deeper and develops blisters. If you have blisters anywhere on your body after finishing the race, don’t assume this is a normal friction blister, but go see the medical team and get the blister examined for being a possible frostbite. Treatment can be rather painful and last for several weeks. Permanent redness on the affected skin may occur as well as the area developing permanent intolerance to coldness.

3) Third degree frostbite is a very deep skin injury causing dead tissue. Instead of extreme white the skin can turn red and purple. A sense of numbness in the area is typical sign of third degree frostbite. Beware, however, that a finger with third degree frostbite can still move, although at reduced function, so don’t let this fool you into believing the injury is less serious.

The sooner frostbite is treated the better the chances of a good recovery so please don’t ignore any of the signs above.
A runner with second or third degree frostbite will not be allowed to continue and/or run the following day if signed up for the Polar Bear Challenge.

Frostbite is avoided by dressing well – see the Clothing section for more details.

Other Considerations

REMEMBER: It's important to avoid dehydration, so make sure you drink enough before the race and drink at all the water stations! Running in the cold will not make you feel as thirsty as in warmer climates, but the route is still 42.195/21.097 kilometres long!

Your skin will have more resistance towards cold when the natural skin grease is intact, so it is recommended not to shower in the morning of the race. As a minimum avoid washing your face with soap. A non-water-based lotion will also give a certain degree of protection if applied a couple of hours before going outside.

Keep moving your fingers while you run, clench your fists and make faces every once in a while.

If you take daily medicine prescribed by your physician or need any other medication, please inform the race doctors in advance by writing to info@adventure-marathon.com
