The Marathon des Sables is known as the toughest footrace on Earth and is the equivalent of six marathons.

The race is a gruelling multi-stage adventure through a formidable landscape in one of the world’s most inhospitable climates - the Sahara desert.

The rules require you to be self-sufficient, to carry with you on your back everything except water that you need to survive and is much a test of the mind as it is the body.
