The Antarctic Ice Marathon is the world’s southernmost marathon, held in the interior of Antarctica at Union Glacier. Participants face extreme sub-zero temperatures and snow-covered terrain in a truly unique endurance challenge.
Course Highlights
The Antarctic Ice Marathon offers a truly unique and formidable running experience, taking place in the heart of the Antarctic interior at 80 degrees South. Unlike other races that stay on the coastal islands, this event is run entirely on the mainland continent, just a few hundred miles from the South Pole. The course is situated in the vicinity of the Union Glacier camp, set against the breathtaking backdrop of the Ellsworth Mountains. Runners traverse a 10.55km loop that is repeated four times to complete the full marathon distance. The terrain consists of a groomed ice and snow surface, which can vary from reasonably solid ice to soft, loose snow depending on the conditions. With no penguins or crowds to cheer them on, participants must rely on their own inner strength and the camaraderie of fellow athletes to push through the hushed, indomitable surroundings of the White Continent.
Race Details
Scheduled for December 13, 2026, the 21st edition of the Antarctic Ice Marathon is an adventure of a lifetime. The race is organized by Runbuk Inc. and is recognized by Guinness World Records as the southernmost marathon on Earth. Participants are flown round-trip from Punta Arenas, Chile, to the Union Glacier camp aboard a Boeing 757 passenger airliner, landing on a world-famous blue-ice runway. The registration fee of $22,500 USD is all-inclusive of flights from Chile, tented accommodation, meals in Antarctica, and official race gear. The race is a member of the Association of International Marathons & Distance Races (AIMS). Underfoot conditions are extreme, with average windchill temperatures of -20°C and the potential for strong katabatic winds from the Pole. A half-marathon option, the Frozen Continent Half-Marathon, is also available for those seeking a shorter but equally intense challenge.
Why Runners Love It
Runners are drawn to the Antarctic Ice Marathon for the chance to conquer the final great wilderness on Earth. For many, it is the crowning achievement in their quest to join the exclusive 7 Continents Marathon Club, which requires finishing a marathon on all seven continents. The event is celebrated for its impeccable organization and the profound sense of accomplishment it provides. Athletes from around the globe share a unique bond, forged in one of the most inhospitable yet beautiful environments on the planet. The experience is not just about the run; it’s an expedition that includes polar briefings, gourmet meals in a remote camp, and professional photography to document every step of the journey. The stark beauty of the glaciers and the purity of the Antarctic air create a spiritual and physical challenge that leaves a lasting impact on every finisher, making it widely considered the world’s “coolest” marathon.
