About the race
Help us raise a MONSTROUS amount of support for local students on October 24th! ISF Monster Mash 5K is a community-based, family-friendly event that raises funds for programs that serve students attending all 27 ISD schools. We welcome all-ages and abilities. Convenient onsite parking, phased start times, and a professionally chip-timed course ensure a great experience for all. You’ll appreciate the flat, paved, out-and-back route whether you’re setting a new 5K PR or enjoying a brisk walk together as a family! Bring your creativity – festive costumes are encouraged! This event sells out every year, so don't wait to register! Every registration submitted by October 11th receives the option of receiving a 2026 Monster Mash technical race tee & medal. Option to waive the shirt (No-Shirt Registration), if wearing monsters isn't your jam - more of your registration fee will go to support students! Registrants are eligible for placement awards, receive free event photos, and raffle tickets for prizes! See below for details.
