Today was my second attempt at W6R3, more successful than my first attempt. My breathing eventually evened out but I had quite a few stops for a few seconds, probably equated to about a minute in total over the whole run. I dont think I would have stopped so much had my lower back not have ached so much. My back doesn't ache every single time I run, not sure if its my posture, my overweightness or my trainers. Feel a bit defeated just now, should I just continue to W7R1 or repeat W6R3? Week 6 REALLY is a toughy!
