Dirt Circus - Los Angeles

Dirt Circus - Los Angeles is a one-day community event organized by UltraSignup that brings together local races, run clubs, brands, and other running-related businesses. The event is presented as a festival-style gathering with a social run, an expo with vendor booths, food and beverages, and a raffle with prizes from brand partners.

The event is hosted at A Snail's Pace Running Shop - Chino Hills, located at 13920 City Center Dr Suite 4042, Chino Hills. The Dirt Circus is visiting Los Angeles for the first time and highlights local race directors and community resources related to trail running.

A group run leaves from the store and moves from streets onto nearby urban dirt trails. Participants can choose between the following distances:

  • 5K
  • 10K

The event is cupless, so water refills require personal bottles or cups. Dogs are not allowed except for service animals. Attendees who check in receive an UltraSignup branded "Shoe Bag Lite" while supplies last, and there will be a face decorating and glitter station. Local partners include A Snail's Pace Running Shop and several race companies and sponsors. An exclusive city t-shirt design is available for preorder, with preorders closing August 9, 2026.
