I was going to post a picture of the route around the UK...but it’s an island so the route looks just like someone’s drawn a red line around the UK ;-). That said, I’ve worked out that doing 30 miles a day it will take 83 days no stop to complete the trip. That leaves me 17 days for bad weather and any days where I don’t hit the 30 miles a day.
The only luxury diversion I’m going to have, is a night calling in at my mates in Portsmouth, and night calling in at my mum’s in Cheshire and a visit to my birth town in Inverness.

Apart from that I could reduce the trip a little by going from Anglesey to the Isle of Man and then onto the Scottish Islands...but that two huge outings.
