<P> The Presidents Race (known as the GEICO Presidents Race for sponsorship reasons) is a promotional event held at every Washington Nationals home game at Nationals Park, and previously at RFK Stadium, in the middle of the fourth inning of every game . If a game goes to a fourth extra inning (i.e., the 13th inning), a second race is held in the middle of that inning . </P> <P> The Presidents Race has featured likenesses of seven former Presidents of the United States, four of whom are found on Mount Rushmore: George Washington, Abraham Lincoln, Thomas Jefferson, and Theodore Roosevelt, plus William Howard Taft (introduced in 2013 and retired after the 2016 season), Calvin Coolidge (who raced for a single season in 2015) and Herbert Hoover (who raced for a single season in 2016). Their nicknames are "George," "Abe," "Tom," "Teddy," "Bill," "Calvin," and "Herbie ." The Presidents are typically dressed in Nationals jerseys numbered according to their term as president (1 for George, 3 for Tom, 16 for Abe, 26 for Teddy, 27 for Bill, 30 for Cal, and 31 for Herbie) and topped with giant foam caricature heads . On Sundays, they usually wear period costumes, often referred to as their "Sunday Best" outfits . </P>
