Dirt Circus - Los Angeles

Dirt Circus - Los Angeles

Dirt Circus is a free, one-day community event organized by UltraSignup. The Los Angeles edition takes place on August 29, 2026 and brings together local races, run clubs, stores, brands, and other businesses that serve the trail running community. The event centers on a social group run that departs from A Snail's Pace Running Shop in Chino Hills and an on-site festival with an expo and vendor booths.

After the group run, the festival area features food and beverages, a raffle with prizes from brand partners, shoe demos, and branded giveaways while supplies last. Participants can meet race directors and learn about upcoming local races, running gear, hydration and nutrition products, and club activities. The event includes a face decorating and glitter station and a store partner presence.

The event is cupless, so attendees are asked to bring bottles or reusable cups for water refills. Dogs are not allowed except for service animals. Preorders are available for a city-specific Dirt Circus T-shirt, with preorders closing on August 9, 2026.
