I can't say I'm used to getting passed by everyday people when I'm thru-hiking. But it happens quite frequently here in Nepal - by school kids to old grannies. For the locals, walking is a way of life.
It's really amazing to see the Nepali culture of walking. Born out of necessity and economic reality, everybody walks to get anywhere. I don't think there is another country in the entire world that can compete. What's more crazy is the people tend to walk in flip-flops. Carrying loads I don't envy strapped from their heads. In mountain terrain. All of this is normal!
It's been quite an honor to hike among such great walkers. If it weren't for my Arc'teryx, Patagonia, and Ray-Ban, I would totally blend in here.
