I'm still up for this wekend, even if the weather isn't. I've done leg 4 before but wouldn't like to take responsibility for navigating. Have you got a base where we could meet up before the start or will you send me your schedule etc for sorting out logistics. I've never done the third leg so I might join you for that as well if you don't mind. Anyway get back to me with your thoughts.
Cheers Richard
