Dirt Circus - Los Angeles

Dirt Circus - Los Angeles

Dirt Circus is a free, one-day community event organized by UltraSignup and presented in Los Angeles for the first time. The event brings together local races, run clubs, brands, race directors, coaches, nutritionists, and running stores to connect with the local trail running community.

The program centers on a social group run that leaves from the host store and moves onto nearby urban dirt trails. Participants can choose between the following route options:

• 5K option
• 10K option

After the run, the event features an expo area with brand booths and vendor tables, food and beverages, and a raffle with prizes that include brand products and race entries. Attendees can speak with race directors, learn about local races, and view running gear and hydration or nutrition products. The host store partner for this edition is A Snail's Pace Running Shop in Chino Hills.

The event is cupless, so participants bring bottles or cups for water refills. Dogs are not allowed except for service animals. Registrants who check in may receive an UltraSignup branded Shoe Bag Lite while supplies last. A city exclusive Dirt Circus T shirt is available for preorder during registration, with preorder availability closing on August 9, 2026.
