United States·2026

Santa Rosa-Petaluma, CA

Running in Santa Rosa-Petaluma is largely urban and flat, with the 2026 Mother's Day Virtual 5K anchoring the local calendar, though serious distance runners head to the relatively gentle surrounding terrain in Sonoma County. Cyclists dominate the scene here—the rolling vineyards and rural roads mean long gravel and pavement routes through the Giro Bello 225km+ pilgrimage distances and the Bike to Hope century are standard territory, with the Petaluma-to-Napa corridor offering consistent 200–300m elevation gain over 40–80km rides. The region's cycling culture is rooted in wine-country road rides and multi-day touring rather than track or urban sprinting.
