Key Highlights :
For keen hikers, there are a number of long-distance trails which could challenge anyone. But none of them has anything on the longest walk on Earth, which comes in at a whopping 14,334 miles (23,068 kilometres) - over six times the Appalachian's length. The route takes you from Cape Town, South Africa, to Magadan in north-east Russia, and is entirely walkable.
Be warned though, it crosses through 16 countries which subject you to desert, warzones, and some of the coldest places on the planet. The 4,500 hours of walking equates to 188 days, but it would realistically take closer to three years to complete this journey at a sustainable pace while accounting for time to sleep.
So, if you are thinking of packing your bags and being the first person to ever do this, here is what to expect along the way. Firstly, according RealLifeLore on YouTube, Earth's longest walk technically starts in L'Agulhas, rather than Cape Town, which is the southernmost point on the African continent. From there you walk up the length of South Africa, and cross into Zimbabwe. At this point you meet your first big danger - the black mamba, or Africa's deadliest snake.
Next the route takes you briefly through Mozambique, Malawi, Zambia, and then back into Malawi. After that you trek all the way through Tanzania to Uganda, which is your next big threat, as one of the malaria capitals of the world - so be sure to have your shot before you embark on this getaway.
And once you are through that, you go straight into South Sudan which, according to the Global Peace Index, is the fourth most dangerous country in the world, as it is embroiled in a civil war. However, you soon get into Sudan, which is a healthy five ranks higher, and could subject you to temperatures of 47 Celsius as you go through the Sahara. Your last stop before leaving Africa is Egypt, which you depart by crossing the Suez Canal and heading to Israel and Jordan.
After brief stint through those, you head into the last active warzone on the route - Syria, which has been engulfed in civil war since 2011. The conflict has been marked by the use of chemical weapons, bombings, and other atrocities. Given that, anyone doing this walk will be keen to get to Turkey as soon as possible, although the route does not go through anywhere especially notable here before crossing into Georgia.
At this point you will meet the edge of the Black Sea, bringing excellent views from the beaches around Pitsunda. Then you cross into the final country, although there are still over 10,000 km to go, as this is Russia. You begin by walking through Sochi, the host city of the 2014 Winter Olympics.
Quickly though, the route leaves the Black Sea and begins its monotonous traipse through the world's largest nation, north of its borders with Kazakhstan, Mongolia, and China. This sees you go right through the width of Siberia, and given the length of the journey, this would likely involve encountering temperatures as low as -39C in the harsh Russian winter.
The final stint of the journey is from Yakutsk to Magadan, along the 'road or bones,' so-called because the gulag labourers who died while building it had their bodies simply mixed in with the rest of the rest of the building material. Any further than Magadan would be practically impossible to get to on foot, hence, this is the destination of our planet's longest walk.
The longest walk on Earth is an incredible feat, and one that could take even the most experienced hikers at least six months to complete. It goes through 16 countries, including deserts, warzones, and some of the coldest places on the planet. The route starts in L'Agulhas, South Africa, and ends in Magadan, Russia, and is over six times the length of America's Appalachian Trail.
The journey is filled with dangers, from the black mamba in Zimbabwe to the civil war in South Sudan, and the use of chemical weapons in Syria. It would be a truly life-changing experience, and if you are up for the challenge, you could be the first person to ever complete it.
