I've just done r3. Well I say done. I managed 7 of the 8. My iPhone paused the training on walk without me realising. My mind was willing but my body wasn't. I ran after work rather than in a morning. Feeling really disheartened even though I did the same route in roughly the same time. I'm pleased I got off my backside and exercised just cheesed off I didn't complete it the way I wanted to. Should I repeat this or go onto W2. My breathing was OKish (better than r1)!!
