Don’t you hold yourself just a little higher, pull in those abs just a bit, correct that arm carriage and perfect your stride when approaching another runner?  The other runner undoubtedly mocking  peacock moves.  Passing friendly faces, smiles and waves.   Once eclipsed, each runner relaxes back into their accustomed stride, just a little easier and more comfortable.

Is it still this way?

May seem an odd question for a Monday morning but its not really.  The answer might very well be the absolute origin of competitiveness.

Competition must start with yourself.  The Best Competition is against others.  And once those days are past, back to competing with yourself.

Its just a little test.  Take it on your  next run.  Are you competitive?
