Nick is raising money for the Brain Research Trust, in commemoration of his brother who died last year of a brain tumour.

I’ll end with a plea for help - if you can afford to donate, then please do, as thinking about the money I’m raising may make the blisters slightly less painful. Also, if you happen to be on or near my route, or fancy a short break in the wilds of Britain, then I’ll be glad of any company on the way, or just for someone to stick my rucksack in a car and take it from the day’s start to the finish. Whatever you do - even if it’s just telling people about the mad long-distance walking blogger - it all helps somehow.
I have been thinking of this as something far in the future and now it has come right near, so can you help support the walking man? Donate money here.
