CTZ @ Castro Street Fair
Hosted by Cycle To Zero
Come visit the Cycle to Zero booth at the famous and always fun and sunny Castro Street Fair. We’ll be set up right in front of Strut, SFAF’s community building and sexual health clinic.
Come chat and connect with staff about CTZ and how to get involved as a Cyclist, Crew, or Volunteer. And bring your friends – we’d love to meet them and answer any questions they have. We’ll have a special registration promotion happening!
See you there!
