Event overview
The Thriller Lake Endurance Run is scheduled for Saturday, October 24, 2026. It is a timed loop endurance event held around Miller Lake at Little Mulberry Park in Gwinnett County, Georgia. The event includes timed 12-hour, 6-hour, and 3-hour formats and a separate Trick Or Treat Fun Run.
Course and formats
The timed events take place on a loop that is 2.2 mile long around Miller Lake. The Trick Or Treat Fun Run follows the same 2.2 mile paved trail and includes eight treat stations along the route. The fun run is not timed and uses glow-in-the-dark wrist bands for participant identification. Spectators and family are allowed in the start and finish area, but everyone on the course must be registered.
Features and prizes
The event includes Halloween-themed elements such as runners in costume, food, and music. A costume contest acknowledges top costumes and awards the overall best costume with tickets to a Falcons game. In 2025, Classic Running and Mount To Coast provided overall winners of the timed events with a choice of shoes redeemable at Classic Running in Buford. PERC Coffee is brewed on site for participants, spectators, and crew. Strollers are permitted on the fun run; bicycles, scooters, and motorized devices are discouraged unless medically necessary.
