I'm reading "Around the World on a Bicycle" by Thomas Stevens on my Kindle. I think he was probably the first person to go around the world on a bike. His cultural attitudes are annoying, and he's not the best writer, but he had the grit to get it done.

A lot of his trip was on foot, pushing the penny-farthing when the road conditions were too bad to ride. This gives me permission to get off and push every now and again.

He also spent some time dangling over railroad bridge trestles while the train was chugging along on the same bridge. Yeah, it is an adventure story.
