'Athlete' in the Bible

It is like a groom coming from the bridal chamber;it rejoices like an athlete running a course.

Now every athlete who [goes into training and] competes in the games is disciplined and exercises self-control in all things. They do it to win a crown that withers, but we [do it to receive] an imperishable [crown that cannot wither].

Also, if anyone competes as an athlete, he is not crowned unless he competes according to the rules.
