This is indeed a very courageous thing to do. And it's also interesting to travel 142 miles by walking. And that too with a heavy bag on the back. It's like military training. But I would like to appreciate them because in this fast-paced era where every convenience is available, or maybe these conveniences have made us very Lazy. In such a scenario, this kind of activity is very good for health.
I think after such trip someone will really have a feeling of a great achievement and satisfaction. I do not know if I would be able to do such long journey maybe just half of it.
