Quite fancy the Cheshire Cat but I will only have the fixed with me at that time...suicide?[/qutoe]
Most of the route is as flat as you can get. -It's a bit lumpy around delemere but last year it was big ring all the way (except mow cop and bridestones).
If you don't mind pushing up Mow-cop, Bridestones and the new hills for this year, macc forest and Swiss hill then you'll be fine. You'll probably find you're not the only rider pushing up these!
Completely different route, doesn't go anywhere near Delamere or over the Bridestones next year.
Much shorter 'flat Cheshire' loop, then Mow Cop, over towards Rudyard, Wincle & Danebridge, Macc Forest, Lamaload to Pott Shrig, Alderley Edge inc Swiss Hill and then back to Knutsford.
I tried Swiss Hill this afternoon, was doing pretty well despite lots of back-wheel slip on the greasy cobbles until the camber caught me.
It's do-able, just not by me today !

But I wouldn't fancy it amongst lots of other people swerving about, stopping, crashing - difficult enough without that additional hazard !
Meself, I wouldn't fancy next year's route on a fixer...
