Last year a group of us decided that it would be a great idea to walk 100km from London to Cambridge. For about 12 hours it felt like the worst possible idea.

Somehow, it has again been decided that it was in fact a brilliant idea and so now we are doing it again. The key difference this time round is that it is in The Cotswolds, which means hillier and ultimately even harder.

I'm doing it again in memory of my mum, who was such a keen walker, and an avid member of the ramblers. She unfortunately succumbed to this terrible disease and it has affected others close to me.

As difficult as this challenge may be, it is nothing compared to what many have to go through, day in , day out.
