Dirt Circus - Los Angeles

Dirt Circus - Los Angeles

Dirt Circus - Los Angeles is a one day community run and festival on August 29, 2026 in Los Angeles, CA. The event is organized by Dirt Circus by UltraSignup and is hosted at A Snail's Pace Running Shop in Chino Hills. It is part of a series of free community events that connect runners with local races, run clubs, stores, and race directors.

Activities include a social group run that starts from the store and moves from streets onto nearby dirt trails; the group run follows staggered waves to reduce trail crowding. After the run there is an expo with brand booths, shoe demos, food and beverages, a raffle with prizes from partner brands, and a face decorating glitter station.

The event operates as a cupless event, so participants should bring bottles or cups for refills. Electrolytes will be supplied on site and attendees may receive a branded shoe bag and fuel items at check in while supplies last. Dogs are not allowed except for service animals.

Volunteers support runner check in, lead and sweep group runs, and assist with the raffle; volunteers are included in the run and festival activities and may receive extra swag. Registration closes on August 28, 2026 at 11:59 PM PT. Preorder for the event t shirt closes on August 9, 2026. Visit the organization's website for the most recent information.
