Not yet Phil, but as per the end of my 'Dovedale Dipper' thread a few posts down in this Section, I shall be imminently posting the Nine Edges Challenge as a Forum Meet-Up.
My wife and I will be entering for certain, and so I suppose shall forum member 'Radder', and hopefully plenty of others too.
In fact, there was a fairly recent forum meet that accomplished a 24 mile version of this walk, although not as part of the official organised event:
http://www.walkingforum.co.uk/index.php/topic,7174.msg71305.html#msg71305 The Nine Edges challenge is 20 miles with 900m of ascent.
It's £20 to enter, plus £2 to hire the electronic 'dibber' that marks you in at each checkpoint.
Your money gets you a pint at the Robin Hood when you've finished, a commemorative T Shirt, and a lift back to Fairholmes.
See you there perhaps?!
