ELI5: Why are races run counter-clockwise?

Whether it's a foot race, horse race, NASCAR, or even a baseball diamond.

The Romans did it that way.  Every time some weird thing doesn't make sense, it's because the Romans did it that way.  Why do we have two twelve hour segments in our day (AM/PM), instead of one 24 hour duration?  The Romans did it that way.  Our months? Roman.

Go watch Ben Hur if you don't believe me.  The chariot race: counterclockwise.
