The Runner Marco Olmo is a living legend of extreme running. In his \"previous lives,\" as he says, he has been a farmer, a truck driver, a workman. Running has become his reason for living, the way to take revenge on his hard destiny. At the age of 58 he became the World Champion by winning the Ultra Trail du Mont Blanc, the hardest and most important endurance race in the world, over twenty hours of uninterrupted running, 167 km (over 100 miles) around the tallest mountain in Europe.
