Week 4 was awesome. As sketchy as Week 3 was, 4 was so much better.
The run/walk intervals, for the first time, were more run than walk. Longer time running, shorter time walking in between. I had some great runs. I felt challenged but not in cardiac arrest. I felt controlled and confident. I felt, kinda, like a runner. A slow one, but a runner nonetheless.
So, onto Week 5. It's over the halfway point and onto my longest continuous run - 20 minutes straight. Here we go!
