About this race

Halloween Fun Run – 5K & 1 Mile (Zombie Theme)

Saturday, October 25, 2025 • 10 AM – 12 PM

320 Chicago Creek Rd, Idaho Springs, CO

Whether you shuffle like the undead, sprint like you're being chased, or stroll like a friendly ghost, you're invited to creep, crawl, and cackle your way through the Idaho Springs Cemetery for our annual Halloween Fun Run! Choose between a 5K or 1-mile loop and enjoy candy along the course, spooky surprises, and community fun that goes grave-deep.

Zombies are highly encouraged—but if you prefer to be a fairy, hot dog, alien, or banana, go for it. Just know… you might be a target for hungry runners in tattered clothes moaning about “braaaains.” All costumes are welcome—let your creativity and comfort do the choosing.

Prizes will be awarded to:

• Best Costumes

• Race winners who make it to the finish line without losing a limb (just kidding… kinda)

Leashed, friendly dogs are welcome—especially those dressed to impress. Matching undead duos get bonus applause.

Please note: distances are approximate—but the fun is guaranteed.
