Just come back from the run. It went surprisingly well. I literally was dreading it as I struggled with W5R2. I was tempted to repeat that run but thought I would give Run 3 a go.
It was hard, but found that I didn't struggle with my breathing quite as much, though some breaths were still difficult and almost started getting a stitch twice. Luckily somehow managed to avoid both.
There was one point when I wanted to stop and walk so badly (must have been around the half way point) but again managed to work past that.
Just so happy to have completed this run and even happier that it definitely wasn't anywhere near as difficult as I had expected, especially after run 2.
Can't believe I only have 4 weeks left!
