Whilst having all this "fun" James is hoping to raise some brass for the John Muir Award, administered by the John Muir Trust. The award aims to increase, "awareness, understanding and engagement with nature and wild places". James is funding the trip himself, so all money raised will go to the John Muir Award.
I wish him well and if, like James and I, you love wilderness and all you find there, you might consider supporting this worthy cause on his behalf. If you're tempted, take a look here where it's straightforward to make donation.
You can read much more about James' endeavor in his own inimitable words on his blog, here.
Good luck James!
By the way, that's James and me, pretending to be mountaineers, in the Cheviots a bit back. Shame he's not as good lookin' as me.
