Are you up for the CHALLENGE?
Sonoma County Backroad Challenge and Backroad Fest at Penngrove Park

Enjoy spectacular Sonoma County scenery on one of the three rides ranging from leisurely to grueling, and stay for local cuisine, cold brews, live music and hearty fellowship.

The Sonoma County Backroad Challenge is an annual fundraising project of the Petaluma Sunrise Rotary Foundation. The Petaluma Sunrise Rotary Foundation, a 501 (c)(3) Charitable Foundation, was established in 2010 by the Rotary Club of Petaluma Sunrise.  Your participation in the Backroad Challenage as a rider, sponsor, volunteer or vendor allows us to continue to do great things for the community and internationally.

The Petaluma Sunrise Foundation is committed to making the Sonoma County Backroad Challenge one of the premier cycling events in Northern California. Thank you for coming along for the ride.
