The postcript is that I did do the LEJoG in 2015, on a road bike, unsupported, using the Cicerone route, and took 13 days. In ten days on a mountain bike? I wouldn't have enjoyed that, what fool suggested it?
I have, its cold, its wet, its windy in summer!
I can see why my Great Granny left it in the early 1900's.
Great beaches though, very scenic and very empty.
I did Stornoway to Barra over two days back in 2013, and enjoyed it although the face wind that you couldn't turn away from was a killer. And I got soaked to the extent that I had to put the clothes that had been soaked earlier back on as they were still drier than my newly wet clothes.
Thence to Oban and over to Aberdeen to get the ferry back home.
