Over 700 brave people did run in very cold conditions the 14th annual Santa Speedo Run in Boston.
The event began in Back Bay in 2000 when five friends decided to put on some Santa hats and take off everything else, bringing holiday cheer to the streets in speedos.
Since then, the race has grown to include hundreds of participants each year and has become an annual holiday tradition in Boston, and it also helps to raise money for charity.
This year, the run raised almost 205,000 dolars, which will go to the Play Ball Foundation, an organization striving to teach Boston middle school students about teamwork, communication, and discipline through sports.
