I'm late in replying, but when this question was asked, that weekend was the beginning of a week off work. I didn't really know what I wanted to do for the whole week, but I did know that I wanted to do a one-day trip to a large city 1.5h away by train, and I would do anything necessary to prepare for it. I ended up going to the library on Saturday to read a tourist guide about that city, then spent Sunday planning the trip, placing pins on my phone's map, packing, and panicking, and then did that trip on Monday. It went super well, though it was super exhausting and I had a headache that lasted through the following day. Then I kept on going for long walks around my own city on every other day and it was refreshing. I walked ~60km in a week.
