Today was my second run post graduation and I made it to the magic 5k. It did take 39 minutes but I was trying to lengthen my stride and it made a difference- same effort, more distance.
I always felt I was running on the spot and only using the balls of my feet while I was doing the programme, partly to protect one foot from the extra pain while I had pf. Now that's passed off I can concentrate on correcting my gait and landing mid-foot.
Anyone who thinks they're slow, listen to the advice on here and don't worry about it at all. I can see now that the distance will increase naturally as you get stronger and fitter π x
