In reply to IPPurewater:
I see your question has been answered but a couple of things to be aware of
Where the road is closed to traffic, you tend to get walkers all over the place! I don't have a problem with this, but it does mean you can't go flat out.
On the 2 mile stretch from the A57 to Fairholmes you tend to get a lot of cars parked illegally, along with the traffic problems that this causes. Maybe it's just me, and maybe I picked a bad weekend, but it did rather negate the enjoyment of the traffic free section !
