Hello! I really want to get through the whole programme - am feeling much fitter already! Snag - W3 is proving difficult. I tried W3R4 last night but couldn't run for the full 3 mins (even though I had got through them before). I felt quite sick and couldn't breathe! I was on a slight incline - don't know if that was why. I want to try again today on level ground. My question is: is it really just all in the mind? What gets you through each run when you hit a low? I think I might need to toughen up a bit!
