Dirt Circus - Los Angeles is a one day community running event in Los Angeles, CA organized by Dirt Circus by UltraSignup on August 29, 2026. The event is based at A Snail's Pace Running Shop in Chino Hills and centers on a social group run that moves from streets onto nearby dirt trails.

The gathering also includes an on-site expo with brand booths, local race directors, run clubs, and vendors. Activities listed for the post-run festival include food, beverages, product demos, face decorating, a raffle with prizes, and opportunities to speak with race organizers and local running businesses. Onsite vendors and brands mentioned include running shoe companies, hydration and nutrition partners, and performance testing services.

The event is cupless; participants are expected to use personal bottles or cups for water refills and electrolytes will be supplied by a listed partner. Dogs are not allowed except for service animals. Volunteer roles are used for runner check-in, leading and sweeping group runs, and raffle support; volunteers are included in the run and festival activities and may receive event swag.
