in the running

Having a chance to win, as in Mary's still in the running for the promotion . Again, out of the running means the opposite, as in He's too old—he's out of the running . [Mid-1800s] Both usages allude to the entry and chances of a horse in a race.

Entered as a competitor in a contest. For example, Is Mary in the running for this election? The antonym, out of the running , means “not entered as a competitor,” as in Ian is out of the running for the job now that he's living in another state . [Mid-1800s]
