you have to run 10K!
I read that somewhere but didn't understand it.
This past week I ran 10K for the second time in my life (run /walk 2mins/1min) in a time not much slower than the pace that I run 5Ks ( 7min22secs per K ) BUT, before when I did run 5Ks at Parkrun, I felt like it was my limit. Now, somewhere deep inside my brain workings, I can somehow start to understand what the writer was saying -- when you get to 5ks and realise that you are only half way -- all of a sudden, 5ks does not seem to be so far to run!!! I think that this realisation will allow me to up my 5K pace a little.
