I did the first run of week 4 yesterday and I finally feel like I'm really running again!
Even though I'd done the whole program before and therefore knew it was possible, week 4 was a scary thought and I even put it off by doing a 4th run of the week 3 podcast! But once I got into it, it just felt so natural to be running more than I was walking. And my legs felt like they had a proper workout too. Even though it has taken almost a month to get back into running, I'm glad I decided to start C25K from the beginning instead of jumping straight back into 30minute runs because I probably wouldn't have been so successful with that!
