Save The Bay, IBM Bay Area, and Facebook are proud to present the 6th Annual Bay Day, in partnership with San Francisco Bay Trail and AllTrails.

Connect, discover and explore San Francisco Bay through the Bay Day Trail Challenge from October 1-31. There’s an experience for everyone with two ways to participate in the challenge: explore 25 miles of trails or complete 5 activities of your choice that connect you to the Bay. New this year, you can form a team with friends, family, or colleagues to compete and challenge one another.

Everyone who completes the Bay Day Trail Challenge will be entered to win a $300 grand prize gift certificate from our friends at REI. 10 runners up will receive 1 year AllTrails pro memberships and AllTrails swag to help guide their next trail adventure.

Share your Bay Day Trail Challenge adventure on social media and tag @saveSFbay #SFBayDay #BayDayTrailChallenge for a chance to win a $50 REI gift certificate every week of October. Register for the Bay Day Trail Challenge and learn more about how to participate by visiting BayDay.org.
