The Dirt Circus is coming to San Francisco, California. Dirt Circus is a series of free community events organized by UltraSignup to celebrate local races, and race directors. We are bringing together the local running community to share everything we love about trail running. The one-day festival will highlight local races, run clubs, brands, and other local businesses. The event includes a social run, food, a raffle with tons of prizes, camaraderie, and so much more. Come and join us under the big top.
