Throo the Boo 2026

Get ready for a Halloween-themed fun run that takes families on a festive route right through the heart of the Louisville Zoo! Rather than running around the perimeter, participants follow the same path used during the popular Boo at the Zoo event, passing spooky decorations and Halloween characters along the way. It's a fun, family-friendly way to enjoy some active play during the Halloween season. Everyone who participates receives a t-shirt and finisher's medal to commemorate the occasion. After crossing the finish line, families can stick around for a post-race Halloween celebration. Plus, all participants get a bonus ticket to return to the Zoo during regular daytime hours so kids can see the animals up close when they're most active. Whether your family is into running or just looking for a festive Halloween activity with a little exercise mixed in, this event offers treats and entertainment without the tricks.
