Well knock me Down with a feather. I've only gone and done 30mins nonstop jogging.
I started a size 18 I'm now a 16 and can jog for a full 4k distance. The warm up and cool down completes the total of 5k
Next to add speed and then distance to actually make up a 5k run.
Thank you NHS C25K
And to anyone still on the journey: keep plooding on. You'll get there. If I can then you can for sure. Take your time,.repeat runs if necessary and don't beat yourself up if you have a bad run. Keep at it and that end goal will be reached.
