Thriller Lake - 12, 6, 3 Hour and Trick or Treat Fun Run 2026

Thriller Lake is a timed loop race at Little Mulberry Park in Gwinnett County, Georgia, using a 2.2-mile circuit around Miller Lake. Runners choose a 12-hour, 6-hour, or 3-hour format; the goal is to keep covering the loop for as long as your race clock allows. Starts are staggered through the day, with the longest race beginning first and shorter races joining later. The same loop also hosts a Trick or Treat Fun Run, where participants complete one 2.2-mile lap instead of racing by time. Trick-or-treat stations are situated along the course, giving the event a Halloween-style feel without altering the basic setup: one lake loop, repeated or completed once. Overall winners receive their choice of shoes from Classic Running and Mount To Coast, and PERC Coffee is brewed on site for runners, spectators, and crew.
