The Chattanooga Jingle Bell Jog 5K is an annual running event celebrating festive winter themes like Santa and Jingle Bells. Participants receive a Santa Suit costume and Jingle Bells for their shoes instead of the usual race shirt. The event takes place in Downtown Chattanooga, where runners dressed as Santas create a unique visual and auditory experience. Finishers are awarded a holiday-themed medal. The event occurs regardless of weather, and there are no refunds available.
