To the nearest mile, the straight-line distance from Land’s
End to John o’Groats (or Duncansby Head) is a mere 602 miles, so the Phantom
jet that logged the fastest ever journey of 46 minutes, 44 seconds clearly had
a big advantage over the road user.
I have always thought that Lizard Point to Dunnet Head, the
most southerly and northerly extremes of mainland Britain, respectively, looked
further apart on the map. Indeed, it turns out that point-to-point they are 4
miles further apart, which would have added 19 seconds to the Phantom’s time.
By road, however, it seems they are 5 miles nearer. Isn’t Google Earth simply
wonderful in helping me work out all this useful information for you?
Anyway, as far as I could estimate in advance, the distance of
my walk (including detours to gather provisions, find camping sites, locate
suitable stream crossing points and climb the odd mountain) would be around 1,200
miles. This turned out to be very close to the reality.
