From The Strenuous Life: Theodore Roosevelt and the Making of the American Athlete by Ryan Swanson, courtesy of LitHub:
During each home baseball game, the Nationals have a presidential mascot race after the top of the fourth inning. The Mt. Rushmore quartet—Washington, Jefferson, Lincoln, and Roosevelt—loop around the field to the delight of Nationals fans. It's good, simple fun. "The only two rules we had," said Josh Golden, the Nationals' director of marketing, "were don't fall down and Teddy doesn't win." And for the first 525 races (yes, 5-2-5), Theodore Roosevelt did not win.
