Bring Your BOO Crew!
👻 THE BOO CREW IS GROWING!
We SOLD OUT in 2026! 🎃 So we're making room for even more ghosts, goblins, and ghouls in 2027! Grab your spot before they disappear!
Get more bang for your costumed buck! Halloween falls on a Sunday this year, making our Saturday morning 5K the perfect excuse to show off your costume TWICE! And here's the spooky part: Halloween won't fall on a weekend again until 2032! Don't miss this rare chance for a whole weekend of costumed fun! 👻
Bring your Boo Crew and SAVE! 👟 Gather 5 or more 5K runners and everyone saves $5! Create a group or join an existing one. The first four runners automatically receive a $5 refund when the fifth joins.
The more, the scarier! 💜
I Ain't Scared (of 5k) Are YOU?
👻 A little spooky. A lot of fun.
🎃 Lace up, light up, and hit the course for the I Ain’t Scared 5K! Whether you’re chasing a fast time, rocking your best costume, or just here for the Halloween vibes, this is your chance to run, walk, glow, and celebrate. 🏃♀️✨
Come ready for costumes, laughs, and 5K fun—because the only thing scary is missing out! 👀
SWAG
👕 Grab the Tee… If You Dare! 👻
Your 5K registration includes a short-sleeved unisex race tee while supplies last. Available sizes are shown during checkout.
Once the race gets underway, you’re welcome to swap sizes if extras are still hanging around. 🎃
Not feeling the shirt? No problem. Choose the No Shirt option during registration and keep your closet a little less haunted. 👀
🎖️ Finish the 5K and earn the hardware! Every 5K finisher receives an I Ain’t Scared finisher medal at the finish line. 👻
