The Antarctic Ice Marathon stands as a pinnacle of endurance sports, being one of only two official marathon events held on the mainland of Antarctica. Taking place at the Union Glacier, this grueling race unfolds at the foothills of the majestic Ellsworth Mountains, just a few degrees away from the South Pole. The 42.195 km (26.2 miles) course is meticulously marked and prepared, offering a route over snow and ice that pushes even the most seasoned runners to their limits.

Recognized by the Guinness World Records as the Southernmost Marathon on Earth, the event challenges competitors with its average windchill temperatures plummeting to -20°C and the potential of fierce Katabatic winds sweeping across the course. Held at an altitude of 3,000 feet, the marathon promises an authentic Antarctic experience that demands not only physical endurance but mental fortitude.

Participants run amidst jaw-dropping remote wilderness, driven only by their determination and the limited support of pre-positioned aid stations. Indoor facilities are nonexistent, making self-sufficiency crucial as runners navigate the course's harsh underfoot conditions of uncompacted snow and ice.

Organized by Polar Running Adventures, the same team behind the North Pole Marathon, this event also serves as a milestone for those aiming to join the prestigious 7 Continents Marathon Club. The Antarctic Ice Marathon is more than just a race; it's a profound adventure that offers stories of resilience and achievement under the most extreme conditions on the planet.

Expect temperatures between -40°C and -10°C (-40°F to 14°F) with strong winds during the Antarctic Ice Marathon in mid-December. While precipitation is minimal, runners should be prepared for frigid air and the potential for blizzards. The race's high altitude adds to the challenge, with risks of dehydration and frostbite.

The Antarctic Ice Marathon is an extraordinary race that invites runners to conquer the frozen wilderness of Antarctica, situated at 80° south, near the South Pole and the majestic Ellsworth Mountains. This marathon unfolds entirely on snow and ice, demanding both physical and mental endurance as participants navigate the slippery, energy-draining terrain.

Set at an altitude of 700 meters (2,300 feet), the course begins and ends at Union Glacier. While there are no specific landmarks, the stark beauty of the surrounding ice fields and mountains is a constant companion. Runners face sub-zero temperatures, averaging around -20°C, with the ever-present Katabatic winds adding to the challenge. The 24-hour daylight creates a surreal atmosphere, amplifying the sense of isolation and adventure.

Covering the classic marathon distance of 42.2 kilometers (26.2 miles), the relatively flat course is marked and groomed, yet the underfoot conditions remain demanding. As the southernmost marathon in the world, it offers a rare opportunity for runners to test their limits in one of the planet's most inhospitable environments. Part of the prestigious 7 Continents Marathon Club, it is a bucket-list event for those seeking an unparalleled running experience.
