The Empty Quarter Run Exploration is open to everybody, the hidden door of the biggest sand desert in the world, located in Saudi Arabia: the Rub Al Khali. The EQRUN EXPLORATION is a walking/running experience accessible to everyone in this Legendary place. It starts from the Center of the Empty Quarter (Rub Al Khali) Desert! This event is THE FIRST EVER DONE, and it was just IMPOSSIBLE to think that one day, in the centre of the biggest sand desert on the planet, a group of adventurers could run a Marathon. It is a unique opportunity to enter and live in an extraordinary place full of mystery and legends. Participants can be runners/walkers, and if you are a desert lover, you can join this experience as a traveller living this experience enjoying marvellous scenarios and short walks
