I attempted to walk the length of Hadrian’s Wall in my week off last week. However, as someone whose work forces them to be entirely sedentary and weekends are spent matching a toddler’s pace, I was woefully underprepared for the task. My brother and I had planned to split the 84 miles into six days of hiking, carrying all of our equipment on our backs. After the first day, a gruelling 17-miler through the city of Newcastle in the baking English summer, we knew we’d made a mistake.
