I was a bit daunted by moving up to W2'to be honest. Four W1 runs and o wasn't finding it easy, but we did it and I made it all the way round. Ankle and back pain dragged me down a bit at the half way point, but I managed to keep going and complete all 6 running sections (very slowly!). Even cheered on by a lovely lady passing us on her bike.
Now planning where we will tweak the run when we need to in week 3 to make it a bit longer, which has to be a good sign Thanks everyone, your encouragement and posts are so helpful and remind me that I'm not the only 50 something overweight non-runner out there feelings self-conscious and a bit sorry for herself!
