What's the Longest Walkable Distance on Earth?

The REAL Longest Walkable Distance on Earth:

What is the longest walkable distance on Earth? If you’ve been on YouTube for a while you might have seen those videos by HAI and RealLifeLore about the furthest distance you can walk. Unfortunately, they were both dead wrong.

You see, what they didn't realize is that the bearing straight, the body of water between Russia ad Alaska, occasionally freezes over, allowing you to walk right across it. Factoring in this crossing, you can actually walk all the way from South Africa, up to Russia, across the bearing straight, and all the way down the Americas to the tip of South America. One journey that took 37,526 km taking you through some of the most dangerous countries in the world, frigid Russian and Alaskan tundras, and South American jungles filled with dangerous animals and plenty of drug smugglers.

And while this route seems crazy, two adventures, Karl Busby and Dimitri Kieffer are actually trying it, and they've already completed around half of it. And yes I know RealLifeLore's video was about the longest drivable distance and HAI's video specifically said they only looked at the longest route according to Google Maps, I just thought that made for a good intro.
