In 2010, Guy Bruneau from Quebec discovered with Google Earth the longest possible straight line on earth without running into a body of water or any major obstacles.
The 8,400 miles (13518 km) path from Liberia in Western Africa to China crosses 9 time zones and 18 countries and territories.
The road goes like this: Liberia, Côte d’Ivoire, Burkina Faso, Ghana, Burkina Faso again, Niger, Chad, Libya, Egypt, Israel, the West Bank, Jordan, Iraq, Iran, Turkmenistan, Uzbekistan, Tajikistan, Afghanistan, Tajikistan again and finally China.
If you could travel about twenty miles a day on foot, it would still take you well over a year to hike this distance in a straight line.
Surprisingly, no one has ever attempted this. Why you may ask?
Not only are you traveling through war-torn areas such as Iraq but trying to get through West Africa and the republics of Central Asia which you’ll have to enter several times can be a visa nightmare.
Furthermore, the borders that you need to cross along Egypt and Libya are closed to tourists.
The most difficult terrain would be the Sahara Desert and the five-mile-high Pamir Mountains on the Chinese-Tajikistan border, both of which lie directly in your unwavering straight-line path.
Will you be the first to attempt this hike and earn your place in the Guinness Book of World Records? Not to mention crossing off 17 countries from your list.
