The Bay Saint Louis Cult Classics 5K takes place in late October in Bay Saint Louis, Mississippi. It starts and finishes at the Mockingbird Cafe on 2nd Street. The Bay Saint Louis Running Company organizes the race, which embraces its movie theme from the outset: participants are encouraged to wear costumes of cult classic film characters.
The route starts and ends at the cafe, simplifying the setup and keeping it centered in town. Costumes can be inspired by 80s heroes, sci-fi legends, or comedy characters, blending the race with a movie-themed gathering. The event also collaborates with Ainsley's Angels of South Mississippi, with race entries supporting their efforts to enable people with disabilities to participate in endurance events along the Gulf Coast.
