Running across the largest salt flat on earth

The Salar de Uyuni is the largest salt flat in the world. Situated at 3,650 meters above sea level in south Bolivia, its 12,000 square km of salt make it the biggest reserve of lithium on Earth. "Salar" tells the adventure of the two athletes Nico Valsesia and Marco Gazzola, who traveled trough Bolivia and ran no-stop for 170 km to cross the Salar de Uyuni, an achievement never accomplished by any athlete.—Mooz Film
