So... I was up to w4r1 and somehow took fright. I mean, Id done run 1, and found it okaaaaay - not brilliant, but just about doable. Then, due to stress and fatigue and a lack of application, I stopped for 2 whole weeks. And THEN, just as I'd told myself I was back in the game I fell down the stairs and really hurt my coccyx, so that was another 2 weeks. Now, I'm not completely fixed, but my back doesn't hurt when I'm walking. So, I'm about to take myself back to week 3 and start again. Please wish me luck and resilience and strength of mind. I really need it.
