Well you've set yourself a test there mate and no mistake. Huge chunks of that are single track (as I know you know) so you'll either need to set off each day at o'crack sparrow fart or ride for a couple of hours between stops. Iron Butt alert!
Having said that, you've got about 20 hours of daylight and 40 years experience to get you through it and there's hardly a spot on the route where you can't stop, have a fag and think "F*ck me, look at that view."
Have fun.
