Thank you all, some good reading and thought provoking comments. Im not pushed on the distance I make each day, it was more so a steer for planning. I'll happily tip along and plan it day by day with regards to where I will stay. There looks to be plenty of camp sites plus worst case ill wild camp late and get going early.
The harder part for me will be getting a buddy or group, I like my trips solo. Im naturally a loner

and enjoy my own company, living by my own rules as I go. I guess my day to day life is so restrictive, kids, wife, job........ I enjoy that space and freedom.My way to recharge the soul
