North America. It's such a cramped little island, 50 meters is all but crossing it. You should be glad you can even go that far without having to revisit your starting position!

50 meters is probably not even the distance I walk to the nearest bus stop that's right up the street... unless they have an issue again, prompting me to abandon all hope and just walk a few miles to wherever I need to get to.

For many Americans, 50 meters is a long walk.
