So after putting it off a couple of days due to the fear of it, I finally completed this run yesterday!! Thanks to those who replied to my earlier post when l was daunted by the 'big jump,' you were right, it is a mental challenge rather than a physical one.
For those about to embark on this run who are also worrying about the big increase in running time then don't despair. It is all a mind game. Conquer the voices in your head, your body will be fine. Good luck!
For me on to W6!!
