In the words of Mr. (Sir?) Branson and inspired by LoungeLizaard I just decided to go for the 5k tonight however long it took.
Well plotted a route on the OS maps app and I tracked it using 3 apps (and am discounting Fitbit as being stingy at 4.98) and I did it! First 5k...Yay!!! As it happens it took me 38 minutes and weirdly despite the colour of my face now, I felt like I could carry on!
At 15 mins I didn't think I'd make it but just kept it steady. I think setting the goal worked for me. If I say 30 mins I aim for that and then psychologically I'm done. Whatever...doesn't really matter. I thought I could do it and now I know I can πͺπββοΈπββοΈπββοΈπ
