The Sonoma County Backroad Challenge cycling event is back for its ninth year. Sponsored by the Petaluma Sunrise Rotary Foundation, this bike ride takes cyclists through the hills of west Sonoma and Marin counties, the Tomales Bay shoreline and city streets of Petaluma.
This year’s ride is May 18 and offers cyclists four different routes depending on skill level. All of the routes start and end in downtown Penngrove.
Entry ranges from$69 to $99. The funds raised support local community service and international projects administered by the Rotary Club of Petaluma Sunrise.
