Our course is about 40 miles through the Carneros region of southern Sonoma and Napa counties. Route is mostly flat with a couple of moderate hills. For intermediate and experienced riders, helmets required. Our ride pace is in the 15 to 18 mph range, with periodic stops to re-group, so no riders will be dropped. This is an unsupported ride so bring fluids, food and spare tube(s). The route is mostly on country roads through the vineyards with little traffic. From Sonoma city limits we take Denmark St., Ramal Rd., Duhig Rd., Old Sonoma Rd., Stanley Ln. & crossroad, Cuttings Wharf Rd., and Las Amigas Rd. back to Sonoma on Ramal. Everyone welcome. We’ll try it if only light rain is forecast; heavy rain cancels.
