When it is Christmastime, you will find that Santa is hustling, shuffling, and dashing. In other words, around the holidays, people like to get dressed up like Santa Claus and go for a 5K run.
This definitely ensures a rosy set of cheeks—but is not very good for keeping a belly that "shakes when you laugh like a bowl full of jelly." The runners in Liverpool, U.K. call their event the Santa Dash and the hundreds of people dressed up like St. Nick call it the Santa Hustle in Chicago.
There is definitely the presence of sportiness found at these events and plenty of milk and cookies to go around.
