Do it, if all goes pear shaped you can call it quits but a really doubt it will, I cycled from John O'Groat to Lands End and an considering doing it the other way round in 2012 - 20 years after the original trip. If it is something you want to do, then do it, it is far better to do it and have some ups and downs along the way than not do it and then regret it.

Having an ambition and working to fulfil it is something many never get the chance (or have the imagination) to do - if you have the chance and the ambition then do it regardless of what the doom and gloom mongers will say.

That's my two pence worth over!
