I've just come across this brave - or foolhardy perhaps - woman who is planning to walk from John o Groats to Lands End. That's the length of Britain; that's some dog walk! Her name's Sophie Easterbrook, her dog is called Patch, and you can follow them on Twitter, read Sophie's blog, and help them to raise money for Dog's Trust along the way.
Take care

Whilst this is a long dog
Whilst this is a long dog walk, surely the round Britain walk by Seb & Flash would rate as the longest in Britain?

He's a young man that would be great to hear on the show, how Flash coped, special preparations, healthcare for such a marathon etc.
Thanks for the show!
