The Marathon des Sables, dubbed ‘the toughest footrace on earth', covers approximately 150 miles over 6 days. That's the equivalent of  6  marathons in 6 days in extreme conditions (think dunes, 50°C temperatures, sand storms, dehydration and limited food & water ).

The race takes place at the end of March in the Moroccan Sahara, where midday temperatures can rise to 50°C. The terrain is uneven, rocky, stony ground, and 20% of the distance is over sand dunes, making this the ultimate endurance race.In addition, competitors have to carry everything they need for the entire race (apart from water and a tent) on their backs.

This desert marathon really is the ultimate human challenge. www.saharamarathon.co.uk
