Yes, I've finally plucked up the courage to do park run. I wasn't last (my not-so-secret fear!) Although I was very near the back, I overtook some people and achieved a PB for 5k which was a great start.
...and now for the question. To improve my speed I am contemplating doing c25k again from week 1, perhaps once a week, but really trying to run rather than shuffle! Has anyone tried this, and did it improve speed? I currently run 5k in around 40 minutes and I would so love to get to 30 minutes.
