Pretty sore from the last few days. Let myself wake up naturally instead of setting an alarm. Woke up at 11.30am because my bladder was about to explode. Not sure how much I'll be able to see/do today, but going to get this day started and see. Probably try to do an exterior walk-around today. I think you can pay a fee to walk a portion of the battlements. Do that another day. A quick trace of the walling, not counting the port walls/forts is about 3.6km. Probably spend two days just on walls
