On one end of the climate continuum of Iran is a desert which has been recognized as one of the world’s driest and hottest places; Dasht-e Loot. It is a large salt desert in Kerman and Sistan and Baluchestan Province, Iran, and is the world’s 25th largest desert. Decorated with Yardangs, this desert is a popular tourist attraction now hosting an extreme ultra-marathon. Paolo Bargini, the organizer of this event, planned this race to start in an ancient caravansary on the west of the Loot desert for the contestants to run 250 kilometers for six days in the first Iranian Silk Road ultra-marathon. The 35 marathon runners have come from many different countries, some of them for the first time. “This will not be out last trip to Iran,” they all say. In this exclusive documentary by Press TV, the filming crew follows the runners to every step of this international event through the gruesome nature of Dasht-e Loot and you will get to learn about the fascinating life stories of some of the athletes in this race.
