In 2019, 21 year old Josh Reid cycled from China to England alone. It was a distance of 15,000 km and took him through 19 countries. Along the way, he had to contend with sleeping rough on the side of the road and fending off wolves to a variety of weather conditions. He captured his amazing journey on video which I have linked below. This is his story.
