After 4 attempts at run 3 of week 5, I am pleased to say I have finally completed it this morning! I am not going to lie, it wasn't easy, and felt like stopping around 12 minutes in, but pushed on through and managed it until the end.
Your advice on slowing down from the start and really pacing myself really helped.
I am so pleased I can move on as I was worried I will be stuck on this run for ever!!
It really is a battle with your own head, positive thoughts and great music all the way!
