I have walked in London, Paris, Rome, Geneva, Lausanne Florence and other cities for many hours at a time. I would often walk in London until I got too tired to continue, and then I would catch the tube back to somewhere I knew, and then I’d walk some more.
I did the same in Rome and Paris. When you take the tube, or the Metro in Paris or Rome then it’s easy not to know how close places are.
A year or two ago there were road works along a bit of road. Now the road works are back, on the same bit of road. Due to it being spring, and due to rain being quite enthusiastic this year, the route (pronounced root, not grout), is impassible. It’s not impassible because of mud, but because of long grass. In the past I would have walked through the long grass to get from A to B, or I would have walked along the river side walk, but because I wear different shoes than before, and because I don’t want ticks, I no longer walk that route until the works are finished.
