Great advice - thanks both of you. That midge forecasting is awesome, the things you can get on the internet eh!!! the routes look ok until glencoe - oooh rating 4 !!! ouch!
I think i've decided the "spine" of my route - NORTH on the Pennine Way from close to where I will be based in Manchester up to either 3 points.
1. close to Carlisle and cut across WEST into Carlisle on the 'Roman heritage' way - then local routes NORTH and onto the Southern Upland way or local routes NORTH to Glasgow.
2. as (1) but head North at Carlise on the 'Roman' way to Jedburgh and connect WEST into the Southern Upland way , taking in 'Borders Abbey way loop ' (historic buildings!!!)
3 Stay on the Pennine way till the near the end and cut across WEST onto the Southern Upland Way near Kelson heading WEST
Depending on time and other factors, just finish the Upland way and rest (!!) , or if going is excellent, find a route to glasgow (via the Clyde Coast Way at Ayr?) and start the 'West Highland Way' and then maybe the Great Glen way, although i'm keen to explore the West islands...
I've yet to full research the Pennine way, so i'll see about that over the next few days and how long it would realistically take to walk the stages I want to.
If anyone has any comments about the above, please feel free!!
