Join us May 17, 2025 on our 200 mile ride through Yolo, Napa, and Lake counties, the most popular and one of the best supported double centuries in California
The route will be the same as last year, heading northwest from Davis along flat roads of Yolo County, then south and west through Winters, around the south side of Lake Berryessa via Highway 128, northwest along back roads including a few miles on the west shore of Lake Berryessa, continuing northeast of the Napa Valley to Middletown, past the east shore of Clear Lake, then east to the Capay Valley via Highways 20 and 16 before returning to Davis.
The route has just under 9,000 feet of climbing, with nearly all of the climbing under 10% – primarily in the 6-8% range, and ending well before mile 150. Note that there is a four-mile section of hard-pack dirt road with a gradual climb halfway through the course
