Fullerton Fit 5K Trail Run

Get ready to hit the ground running at the City of Fullerton's first-ever 5K Trail Run! On November 22, 2025, from 8:00 to 11:00 AM, we're bringing you more than just a run—this is a full-on celebration packed with community spirit, health, and wellness. Imagine yourself dashing through the breathtaking Brea Dam area, surrounded by the lush landscape that our trail has to offer. Remember, though, this adventure is best suited for the sure-footed, ages 10 and up.

But hold up, the fun doesn't stop when you cross the finish line! Stick around for our Health & Wellness Fair where you'll connect with amazing local vendors, witness fitness in action, and discover new ways to keep yourself in top shape from head to toe. And hey, don't race on an empty stomach—indulge in the tastiest, healthiest treats from an array of food trucks! Whether you're a competitive racer or a cheering bystander, your presence will mark the beginning of an exciting Fullerton tradition. Plus, snag your very own race swag—finisher's photos and video, an awesome race t-shirt, a well-earned medal, and an eco-friendly reusable water bottle. Let's make history together!
