where is the race

Union Glacier, Antarctica

Each year, more than 100,000 people journey to the Antarctic region, yet 99% never set foot on the continent itself.

We take you into the true interior where very few have ever stood, and even fewer have ever run.

how we get to antarctica

Blue-ice Runway

Soar above the white continent at 30,000 ft, passing its tallest mountain ranges before landing on the world-famous blue-ice runway, a rare aviation experience reserved for a few expeditions each year.

For over two decades, our marathon team has made this extraordinary landing with one purpose: bringing the spirit of endurance to the heart of Antarctica.

Testimonials

"The Ice Marathon was one of the most memorable and enjoyable weeks of my life. Union Glacier is an enchanting backdrop for a race, and every aspect of the experience is 5-star. I met a tremendous group of runners, the camaraderie is wonderful. The race is a huge challenge and the most perfect way to combine sport and visiting such an incredible part of our world."

Shirley Thompson (Ireland), Jungle Marathon organiser

"The Antarctic Ice Marathon was the most exciting, uplifting, inspiring, emotional and tiring experience of my life. I was very proud and privileged to be in Antarctica, never mind being part of an international field of runners who were a great bunch, all with a story to tell. Life will never be the same again."

John Killingworth (Great Britain)

"The entire expedition was impeccably organized. The race is also infinitely more spectacular than other events held on islands near Antarctica, yet it is achievable by anyone with determination who seeks a challenge. The Ice Marathon completed my 7th continent and eleven of us received the 7 Continents Marathon Club medal in 2012."
