I did it. Despite a sad day yesterday (lost one of my dogs suddenly and unexpectedly) I did what I'd promised myself, got up and ran parkrun. Not sure how I did, but I got round without stopping. First time I've run without the podcast or music, and I didn't track the run so I found it difficult to pace myself. I know I was finding it hard work by the last kilometre. I'll let you all know my time when I get it later today.
The parkrun itself is a brilliant experience. I've never taken part in anything like this before. I totally recommend it to everyone.
