Completed W1R3 yesterday and am so proud of myself!
I ended up running it on a treadmill as I was away with work, and must admit although it felt slightly easier on my knees and shins, I realy missed being outdoors. My breathing felt so much better too.
I think I'm going to do another W1 run tomorrow, just to mkae sure I'm ready for Week 2 on Sunday......something still in the back of my mind makes me think that W2 is going to be a mammoth step!!!
