Thriller Lake - 12, 6, 3 Hour and Trick or Treat Fun Run

Lace up your running shoes and don your most creative costume for the Thriller Lake - 12, 6, 3 Hour and Trick or Treat Fun Run, a Halloween-themed endurance challenge and festive family event taking place on October 24, 2026, in Dacula, GA. This unique race combines the thrill of timed running with a spooktacular celebration around the picturesque Miller Lake at Little Mulberry Park.

The core of the event features 12, 6, and 3-hour timed loop races on a 2.2-mile paved path that encircles Miller Lake, winding through the scenic surrounding woods and the Karina Miller nature preserve. Runners can expect a course that is largely flat or nearly flat, with approximately 70 feet of elevation gain and loss per loop, making it accessible while still offering a challenge for those pushing their limits. For the endurance events, headlamps are required as participants will experience running into dusk and darkness. Aid stations at the start/finish area will provide typical fare and water, with an additional water stop at the halfway point of the loop.

Beyond the timed races, the Trick or Treat Fun Run welcomes participants of all ages for a single lap of the 2.2-mile course, starting at dusk. This untimed event transforms the trail with trick-or-treat stations manned by costumed volunteers handing out candy, creating a magical atmosphere for families and fun-runners alike. Costumes are highly encouraged across all distances, with prizes, including Falcons game tickets, awarded for the best outfits. Typical race day conditions in late October in Dacula offer pleasant running weather, with highs around 70°F and lows near 49°F, and only a 12% chance of precipitation. Spectators are welcome to join the Halloween party atmosphere, complete with music and food, making Thriller Lake an unforgettable experience for everyone.
