Petaluma Sunrise Rotary Club hosts an incredible rolling journey along the pastoral country roads of Sonoma County with 3 Cycling events: Full Century, Metric Century and Half-Metric. The ride starts and finishes at the Lagunitas Brewery in Petaluma, and explores Sonoma Valley and the coast. Beautiful scenery, challenging hill climbs, a noble charity event, and well stocked and friendly aid stations make this ride the hit of the spring cycling season. Stay for the post-ride Backroad Fest at Lagunitas Brewery with gourmet food vendors, live music, massage tables, cycling oriented merchants, community organizations, and beer.
