I'm due to do w5r2 at the weekend but I've looked it (and w5r3!) up and I just don't see how I'm going to make it! I did w5r1 yesterday and found that when Laura tells me I'm halfway I start thinking 'oh I feel tired already, how am I possibly going to manage this?!'. It turned out that I could manage it and did all three 5 minute runs in full (and felt amazing afterwards!) but I'm really worried about the next lot. I've never run for 8 solid minutes in my life! How do you get over the mindset that you can't do it, and how do you carry on running even when you think you're too tired?!
