I've just attempted W5R2 - I managed my first 8 minutes fine but then stopped in the second 8 minutes with about 3 minutes to go. I'm kicking myself and feeling a little disheartened, and W5R3 seems like an impossible goal at the moment. I just wanted to know if anyone had any motivational tips I could use. Unlike a lot of you I'm a treadmill runner (have to make use of that gym membership somehow)! I generally like the constancy of it and the fact that it's easier to control your speed. Also that you have screens to watch to distract you. I'm not really sure why I stopped, I did try slowing down a little (although I don't run fast anyway) but this didnt seem to help. I'm sure that I could have done it, but I'm really disappointed that I didnt push on.
