Desert Ice Mountain Jungle What extreme environment are you ready to test yourself in? Our series of four ultra marathons are set in the most remote and hostile environments on earth. The Ice Ultra is a race within the Arctic Circle – Europe’s last remaining wilderness. The Jungle Ultra takes runners into the dark heart of the Amazon Rainforest. The Desert Ultra crosses the Namib – the world’s most ancient and hostile desert. And the Mountain Ultra climbs one of the largest and least explored mountain ranges in the world – The Tian Shan Mountains in Kyrgyzstan.
