Yes, 158 is more “normal” but still good. Those numbers tell the story that you are much better for 5k than 10k as the equivalent of your 5k PB for 10k distance would be a sub 40’ time.

I recently set a 10K PB in a race! 55:50 overall time; not close to some of the times above but 2 minutes faster than my previous race best.
