Thanks Ian and Jeremy,

I've gone back to the drawing board and planning a FWE route as suggested, I'll then add sections I'd "like" to do if weather permits and I feel up to it.

I reckon my kit weighs around 10kg (inc 4-5 days of food), just need to lose 10kgs of body weight over the next few months and I'm all set, oh and get a place on the challenge of course!

Thanks for the info everyone!
