Goes to show that the staging of the event is only really a small part of the event.
The biggest component (not only time wise) is still the 1400km+ of roads that everyone has to cycle. Even then, the route itself is only a small part of that, the rider is responsible for the huge physical effort of riding those roads.
(Alston was one of my favourite controls, I ate there both times and had my best sleep there - 4h or so in a comfy bed - although it helped that I'd left Eskdalemuir just before they stopped [or strongly advised] people not to go out).
