About this race

Lace up your running shoes and join us on on October 31st for a frightfully fun day of racing!

The little monsters (ages 10 and under) kick things off at 12:00 PM with the 400 m Zombie Zoom, a quick run perfect for our youngest ghouls.

Then at 12:15 PM, the Monster Dash takes off with your choice of a timed 5K or 10K. Whether you're chasing a personal record or just out for a haunted good time, there's a distance for every runner.

Costumes are encouraged, so come dressed to scare!

Run fast! The first 100 finishers will take home a custom race medal, so don't get caught dead at the back of the pack.

Note: High schoolers in full monster costumes will be chasing and scaring during the 5K and 10K race. Options to not be chased.
