I agree completely with Steve and Dave. You certainly won’t embarrass yourself, whatever your time - unless you start elbowing old ladies out of the way and screaming obscenities at any one who dares to beat you

... But, as you’re the kind of person who would interrupt a training run to help an injured bird, I really don’t think that’s likely.
Enjoy the 10k and don't forget to smile for camera when you cross the line
