Get ready to creep, crawl, run, and shuffle your way through the Idaho Springs Cemetery at our annual Halloween Zombie Fun Run!
Whether you sprint like you're being chased, shuffle like the undead, or stroll like a friendly ghost, there's a distance for everyone. Choose between a 1-mile course or a 5K, and get ready for candy, spooky surprises, zombie encounters, and plenty of Halloween fun along the way.
🧟 Costumes are highly encouraged!
Zombies are always welcome—but if you're more of a fairy, hot dog, alien, banana, or anything else, go for it! All costumes are welcome, so get creative and wear whatever makes you feel comfortable and ready to have some fun.
