Dirt Circus - San Antonio
Dirt Circus - San Antonio is a one-day community run and festival organized by Dirt Circus by UltraSignup on December 2, 2026, at 4001 Broadway in San Antonio, TX. The event brings together local races, run clubs, brands, and businesses to showcase trail running and local race communities during The Running Event and San Antonio Marathon Week.
The program includes a social group run of 3.9 miles, an on-site expo with brand booths and local race directors, food and beverages, and a raffle with prizes. Participants may receive an UltraSignup branded shoe bag at check-in while supplies last, and a face decorating and glitter station will be available. Preorders are offered for an exclusive Dirt Circus T-shirt design for the San Antonio edition; preorders close November 11, 2026.
This is a CUPLESS event, so attendees should bring reusable bottles for water refills. No dogs are allowed except service animals. Headlamps are recommended for trail visibility. The route will be marked and participants are encouraged to save the route to a phone or watch to assist with navigation. The event partners with Soles4Souls to collect gently worn sneakers for donation and lists local partners, sponsors, vendors, and run clubs as part of the festival.
