Littleport to Upwell section especially nice. Good visibility nice open corners and quite in terms of traffic.
(Upwell to Littleport section) fantastic road , you should ride it a few times as it is basically a mini TT course, There are some very tight corners and switch backs with a few straights to get up to top wack. Never seen a copper yet and ride it every week. there are the odd lorry and tractor so be carefull. Road surface is good but a few bumps to catch u out over a ton. Wana do a mini tt then this is teh one for you. fastbikes.org.uk
Not particularly technical but a good fast stretch through rural east anglia, the flatness makes it pretty visually uninteresting but good for a speed run.
