250 kilometers in six stages in the Moroccan desert, between desolate landscape on stony tracks and magnificent scenery in the middle of the dunes: for 36 years, the Marathon des Sables has claimed the title of the toughest race in the world. To the difficulty of the course is added the obligation to run in self-sufficiency, that is to say with its sleeping equipment and its food.
Among the 672 entered in the 2021 edition, Olivier Crouvizier. This landscape painter from Lyon dream of this race and more since its successive postponements due to the Covid pandemic. The project of this confirmed trail runner consists of running eco-responsibly without emitting waste. But when the temperature is close to 60°C, he engages in a fiery race, quickly hit by a tragedy. A moving experience.
