Have now done the week 7 run four times... struggled the first time and had to stop for a couple of minutes halfway through. Then I completed it successfully the second and third times, enjoying it and having no problems. Today I thought I'd get out and do it once more - but I had a stitch after about 15 minutes. I walked it off after about three minutes, so kept going for three minutes after Laura told me to stop, to make up for my lapse in the middle! I felt so good that I did a 'bonus' couple of minutes on top of that, just to make me feel a bit better about myself!
I'm now not sure whether to keep doing the week 7 runs until I truly master this level, or now move on to week 8. Any thoughts from all you experts out there?
