Atacama Crossing
The Atacama Crossing is a 6-day ultra marathon through the driest desert in the world, the Atacama desert in Chile. As well as the distance and the heat, the altitude also forms an enormous challenge for the runners, with most of the race being run above 2,500 metres. The Atacama Crossing comes in second place in the top 10 of endurance competitions, after the Dakar Rally.
