OMG I can't actually believe; but I have just run for an whole 20 mins!!!!
I really had to fight the gremlins beforehand; I thought of all the wonderful advice from you guys (& gals) on here and how I wouldn't want to let you down and most of all let myself down; so the gremlins got booted out the way!
The first five mins were the hardest; maybe because I knew there was still 15 to go? But when I reached the 10 min mark I felt I'd got into a rhythm and thought YES I'm going to so do this!!!
