The Thriller Lake Endurance Run is a festive Halloween-themed event held at Little Mulberry Park in Gwinnett County, GA. Runners tackle a 2.2-mile paved loop around Miller Lake, with options for 3, 6, or 12-hour timed endurance challenges. The event doubles as a lively Halloween party, featuring music, food, and a highly encouraged costume tradition. Families and casual participants can join the Trick or Treat Fun Run, which includes candy stations along the course and a special treat bag for kids. Competitive runners can vie for prizes, including shoes from Classic Running and Mount To Coast, while costume enthusiasts compete for tickets to a Falcons game. With PERC Coffee brewed on-site and a community-focused atmosphere, it is a unique way to celebrate the season.
