About this race
Get ready for a spooktacular evening of movement, community, and giving back at Monster Dash 2027!
Join us on Saturday, October 23, at Central Park in Rancho Cucamonga for a Halloween-themed 1K or 5K run/walk along the Pacific Electric Trail. We’ll start just outside the community center—come dressed in your favorite Halloween costume or wear your race shirt, and bring your friends for some group-costume fun! Whether you’re running, walking, or enjoying the course with your family, everyone is welcome.
Celebrate your finish with a commemorative medal, post-race snacks, and a vendor fair featuring food, drinks, and activities for all ages. Registration includes a raffle entry and the opportunity to try On running shoes through free race-day demos, while supplies last. Race shirts are subject to availability for late registrations.
Every step supports a meaningful cause. Proceeds will be donated directly to Warrior for Children, a local nonprofit helping children navigating trauma thrive through tangible resources, trauma-informed education, and small-group relational experiences.
Lace up, dress up, and help make a difference for children in our community!
