It is not "The End of The World" if your bike breaks down in the UK. Anywhere. I've ridden that north coast road twice in the dark, and at no point was I fearsome afraid (and I'm at the risk-averse end of AUK). Sure there is more risk than in Berkshire, but "End of the World"??
Get a grip people. Save the hyperbole for those "epic" sportives amusingly named after mythical creatures.
