Thanks to the encouragement from people here, I made myself get outdoors this morning. It was, as everyone says, harder but more enjoyable and left me with a greater sense of achievement and wellbeing. I was fine with cars going past but have to admit to speeding up a bit when I was going past an actual person! Some technical probs as phone stopped giving sound when I put it in pocket, so ended up carrying it which made me feel a bit of a bumpy, but hey ho! Now wondering, do ai repeat week four outdoors or press on?
