Antarctic Ice Marathon and Half Marathon

The Antarctic Ice Marathon takes place at 80 Degrees South, just a few hundred miles from the South Pole at the foot of the Ellsworth Mountains. 

This race presents a truly formidable and genuine Antarctic challenge with underfoot conditions comprising snow and ice throughout, an average windchill temperature of -20C, and the possibility of strong Katabatic winds to contend with. Furthermore, the event takes place at an altitude of 700 metres.

Running a marathon is an arduous task. Running on snow, in sub zero temperatures is even more challenging. Participants in the Antarctic Ice Marathon are not required to have previous marathon experience; however, all applicants must be prepared to train properly and should be able to walk or run their race distance very comfortably. Experience in the cold is preferred and will be an asset, but is not essential.

The Antarctic Ice Marathon is the only official marathon run on mainland Antarctica and is a member of the Association of International Marathons & Distance Races (AIMS). It takes place at 80° South, just a few hundred miles from the South Pole in the interior of Antarctica. This is the southernmost marathon on Earth and a unique opportunity to complete a marathon that is truly worthy of the seventh continent. For those who fancy a shorter distance, a half marathon of 13.1 miles (21km) presents a considerable challenge over the same hushed, indomitable terrain. .

Runners will race a groomed and marked course with snowmobile support, aid stations and medical personnel at hand for the duration of each race.

Registration is limited and places are allotted on a first come first served basis only. This event sells out every year. If it's your dream to do the Antarctic Ice Marathon you need to book early to avoid disappointment.

The 3d Itinerary will see you fly by private jet from Punta Arenas, Chile, on 12 December, to the marathon location at Union Glacier, Antarctica. A marked course will be prepared in advance and snowmobile support, aid stations and medical personnel will be at hand for the duration of the race. Runners are scheduled toreturn to Punta Arenas on 14 December. 


The Antarctic Ice Marathon includes an option to run the Frozen Continent Half Marathon which is held concurrently with the marathon.


The Antarctic Ice Marathon route encompasses a 25km circuit followed by a 17.2km circuit as depicted below.A time limit of 6 hours may be imposed on the half marathon and 10 hours for the marathon.

The Antarctic Ice Marathon camp is operated by logistics partner Adventure Network International. It is located in the southern Ellsworth Mountains on the broad expanse of Union Glacier. The setting is spectacular and the accommodation is comfortable. Majestic peaks rise in all directions and there is little wind, providing a comfortable environment to relax in.

Only Accessible by Air
Union Glacier Camp is only accessible by air and the journey involves a 4¼ hour flight from Punta Arenas, Chile. The wheeled IL-76 aircraft lands on a naturally occurring ice runway on the Union Glacier, where competitors take their first steps in Antarctica. They will then climb aboard a specially adapted van for a 5 mile (8km) ride to camp, where a warm welcome awaits you.

The Only Facility of its Kind
Union Glacier is the only facility of its kind in Antarctica. It is a full service camp operating during the Antarctic summer (November through January). The logistics company also maintains and operates the ice runway, a separate ski way and an efficient logistics hub to provide support to private expeditions and National Antarctic Programs.

Much goes on behind the scenes to ensure the safety and comfort of visitors on the ice. Communications experts keep regular contact with the outside world. Heavy equipment mechanics maintain and operate a fleet of transport and runway maintenance equipment. A meteorologist provides weather information to flight crews. The general support staff do the thousand-and-one tasks that keep camp in tip top shape.

Sleeping Accommodation
Antarctic Ice Marathon competitors will stay in double walled sleeping tents that are roomy and comfortable. They are well suited to Antarctic conditions and are based on a design used by Shackleton’s Endurance expedition. Each tent houses two guests and each will sleep in a polar sleeping bag provided as part of the race registration costs. The tents are naturally heated by the 24-hour sunlight and interior temperatures range from 25°F – 68°F (4°C - 20°C).

The dining tent is the heart of the camp. It has a full kitchen and dining area and serves as a gathering place for meals, activities and conversation. Competitors will enjoy hearty, fresh-cooked meals while self-serve snacks and beverages are available at any time. The logistics company also regularly fly in fresh fruits, vegetables, fish, meats and a variety of beers and Chilean wines from Punta Arenas, Chile.

Union Glacier has a small clinic staffed by a doctor and medic. They are available to treat minor injuries and illness or in case of a medical emergency. A selection of medications and fundamental equipment for the care and stabilisation of patients is also stocked.

The camp has men's and women's toilets housed in centrally located structures. There is a men's urinal, unisex toilet and women's toilet. All of these facilities are kept well-stocked and spotless by camp staff. Anti-bacterial hand gel is provided for hand cleaning.

All human waste is removed from Union Glacier Camp. Urine is kept separate from faeces for ease of transport. Men's (stand up) and women's (sit down) urinals are provided. Toilet paper is disposed of in the receptacles provided. Urine is collected in large plastic containers (IBC's) and transported to Chile for appropriate disposal. Separate sit down toilets are provided for faeces. This is bagged and also removed from Antarctica for proper disposal in Chile.

Communications and Meteorology
Good communication and weather information are crucial for safe operations. Not surprising then that the Comms facility is the centre of “on ice” operations. Satellite phone, VHF and HF radio maintain regular contact with the logistics company's Punta Arenas office, field parties, aircraft and other bases. It is possible to make outgoing Iridium phone calls from Union Glacier and pre paid phone cards may be purchased at the camp. The on-site meteorologist uses local observations, information from automatic weather stations and satellite imagery to provide wind and weather information to flight crews and expeditions.

Power and Charging
Systems are solar powered to minimise environmental impact and there are limited solar/charging facilities to guests. Competitors will need a 12V DC-DC charger capable of plugging in to a “female” cigarette lighter socket to use the system.

Two specially adapted 4x4 passenger vans are used for excursions around Union Glacier and to shuttle guests to and from the runway. There is also a fleet of specialized vehicles for snow clearing, runway maintenance and ground transportation in Antarctica. These include an industrial snow-blower, several tractors, snowcat, skiway groomer and a number of snowmobiles and sleds. A team of mechanics operate and maintain these machines.
