Have Class In The Race.

Class is calling on reserve energy.
Class is the ability to overcome any number of challenges during the race.
Class doesn't mean you don't get tired, but it does mean, you never show it.
Class, doesn't mean you never tempted to quit sometimes...
...but it does mean, you never actually do.

And in the final yard of the race, class, makes the different.
