WHAT'S THIS NOW?

The course of the Atacama Crossing takes competitors across a distance of 155.3 miles through the driest non-polar desert in the world. Starting at just below 10,500 feet in the Arcoiris Valley, the race gradually descends over the six stages to finish in the quaint town of San Pedro de Atacama in northern Chile.
