The "ugliest 5K on the planet" is set to kick off Saturday morning in Chicago.
Runners participating in Chicago's first ever Ugly Sweater Run will take their marks for a 3.1 mile jog at Montrose Harbor Park. The race begins at 11 a.m.
The run, which isn't timed, is "less about speed and more about enjoying a crazy day with your friends and family," according to Jeff Suffolk, President of Human Movement Management, race series operators.
Participants will be decked out in their worst holiday sweaters for a holiday themed course. The start line will have snow machines, reindeer games and holiday music. Aide stations feature hot chocolate and sled hills for those who need a break from running.
At the end of the course, participants can celebrate a successful run with hot chocolate or Winter Lager.
The race raises money and collects toys for "Toys for Tots."
While this is the race's debut in the Windy City, the race is also held in six cities across the country and in Moscow.
