Bay Day is a regional holiday celebrating the heart of our home – San Francisco Bay. This month-long event gives everyone an opportunity to explore and connect with the Bay. Thousands participate and there are activities for all ages and abilities.
Bay Day is free of cost, and anyone can participate from anywhere—in teams, or on their own. Our month-long format and various options for the Bay Day Challenge allow for flexibility and easy access!
Participants can register to take the challenge in two ways:
  • 30-Mile Challenge: Explore the Bay and walk, bike, run, wheel, or paddle a combined total of 30 miles of local shoreline trails
  • Bay Activity Challenge: Create your own adventure and complete 10 activities – of any type – that connect you to the Bay.
Create your own activities, or find inspiration in our Challenge Guide. Participants will also receive emails each week of Bay Day with additional ideas, and regional spotlights.
You can only register and track your results through our online system for one challenge, but there is no limit to the ways you can explore the Bay and the miles/activities you can complete.
Everyone who completes the challenge will be entered to win our grand prize: San Francisco Bay Guided Kayak Tour with Sea Trek, for up to 12 people. 2 runners-up will receive $100 gift cards to Sports Basement.

Don't forget to follow us on Instagram @savesfbay and share your adventure with #SFBayDay #BayDayChallenge. Each week we'll have social media contests and give away $50 Sports Basement gift cards.
