Hexham to Portsmouth cycle

[Dave Ludlam]

Hi, I've been tasked with organising a cycle route for students from Hexham (Northumbria) to Portsmouth. We have a 7 day window next Easter/Summer, so roughly 60 miles a day.
Any views/experiences/not to be missed sites/accomodation info all gratefully received.
Have looked at CTC route but want other opinions please.
Thanks
Dave
