The Silk (丝绸) Road Bike Tour: is it the greatest trip in the world? Cyclists call it “the longest, hardest, highest, hottest, coldest bicycle tour in the world”. In eighteen weeks, you travel over 12,000 kilometers through seven different countries and have the most exciting ride of your life.

“A thousand years ago people went by camel (骆驼) and did about twenty-five kilometers a day,” said one cyclist, “But on a bike you do twenty-five kilometers in an hour.” And along the way you see some of the most beautiful places in the world.

From Shanghai, you go across Asia, through Iran and arrive in Istanbul, Turkey, at the end. You travel across the deserts (沙漠) of China and cycle the Pamir Highway to over 4,600 meters across the “Roof of the World” in the mountains Tajikistan.

On the way there are villages, markets and ancient (古老的) buildings. At night, you stay in ancient roadside hotels or in camps. A chef cooks dinner for about half of the days; on other days cyclists can eat in local restaurants or shops in local markets for their food. One cyclist said, “The best thing was the friendliness of the people.” And the worst things? “The snow and the cold in the Pamirs.”

So is it the greatest trip in the world? Cyclist Miles MacDonald thinks so. “The Silk Road Bike Tour is a true expedition (探险). It is long and difficult, but it’s such an amazing experience that you arrive in Istanbul a completely changed person.”
