Conquer 138 miles of iconic climbs and coastal vistas in California’s ultimate cycling challenge.

Levi's GranFondo returns April 17–19, 2025, in Windsor, Sonoma County, offering an exhilarating festival atmosphere and multiple course options—from a free, family-friendly ride to the epic Growler, one of North America's toughest single-day cycling races. The event blends thrilling routes through vineyards, redwood forests, challenging climbs, and dramatic ocean views with a vibrant two-day festival of live music, local food, and community. Since its founding, it has combined world-class cycling with charitable impact, raising millions for regional youth charities.
