Well, I've sort of done my third run of week 4. However, I've not really managed the second slot of 5min more than once, and have been defeated by some stupid hills. No way will I be managing week 5, so repeat it is! However, this is coming from somebody who couldn't do Week ONE or run for a whole minute, and had to repeat the very first week! So I'm going to look at the positive progress!
I'm posting this in case anyone else is in a similar place (whatever stage of the programme they're at). We're not in a rush to the end, and even a bad run with some extra walking is better than sitting on the sofa!
Now enjoying the nice walk back, which one day I might be able to run as well. I still did my total time today, just needed extra recovery.
