Visitors to Marrakech will be able to book Ouarzazate tours at the end of March to be spectators at the 24th Sand Marathon.
Known as the Marathon des Sables in French, this gruelling event sees competitors embark on a 150-mile race through the desert outside Ouarzazate.
The contest includes a full marathon on one day as well as a 50-mile race and other events of varying lengths on different terrains.
Set to take place between March 27th and April 6th this year, the Sand Marathon will see more than 850 competitors on the starting blocks ranging in age from 16 right up to 71.
This will break the record of 801 runners that was set last year, all but 50 of whom completed the race despite its length and difficulty.
Visitors on tours of Ouarzazate and the nearby Ait Ben Haddou can see sights including the valley of the Draa river and the oasis town of Zagora, which is surrounded by palm tree plantations.
Why not book the Ait Ben Haddou & Ouarzazate tour in advance?
