KING RIDGE
March 28th, 2026 Register
The King Ridge Grasshopper is a legendary ride in Sonoma County, challenging cyclists with steep climbs, thrilling descents, and varied terrain. Known for its rugged beauty, the course winds through remote mountain roads and offers breathtaking coastal views. It’s an unforgettable adventure that tests endurance and skill, capturing the gritty spirit of Northern California cycling. For 20 years all of the Hoppers were in Sonoma County. We’re calling this loop the “Greatest Hits” as it includes classic CRRs; (Certified Ribbon Roads) Joy Rd. Coleman Valley Rd. Meyers Grade. Fort Ross Rd. Kruse Ranch. Seaview Rd. King Ridge Rd. Can you hear the soundtrack playing? A mixture of reggae, yacht rock and Grateful Dead maybe. With a perfect blend of adventure, exploration and shred, this is a Grasshopper not to be missed.
Plus, join us Friday for a shake out ride from Monte Rio and Sunday for a bonus social fun ride from Duncan’s Mills!

Riders will roll on their own or in small groups in order to arrive shortly before their designated start times. The first timed segment begins at the bottom of Joy Rd. The segment will open at 9 am. Riders will be scored based on the cumulative time for the 3 segments (long course) and 2 segments (short course).
This format and course will ensure that we have an amazing ride on open roads. There are no timed segments on California State Highways.
Riders may start at any time on Segments 2 and 3. Please don’t gather at the start of the segments in order to keep the road clear and avoid errors in chip readings.

Starting in Monte Rio, a town known as “Vacation Wonderland”, the King Ridge ride takes you into Sonoma County’s coastal mountains. Known for its remote, winding roads and stunning views, this route offers a real challenge with steep climbs and satisfying descents. You’ll ride through redwoods, meadows, and along high ridges, experiencing some of the best—yet toughest—terrain Northern California has to offer. It’s the perfect mix of history and rugged adventure.

In Duncans Mills and Cazadero, May offers ideal riding conditions with temperatures ranging from the mid-50s in the mornings to the mid-70s during the day. It's typically dry, with a slight chance of coastal fog creeping in, especially in the mornings, keeping things cool and crisp. Afternoon sun can warm things up, but expect winds on the ridgelines that might add a challenge during descents or on exposed sections. Layering is key to stay comfortable, as temperatures can shift, but the riding will be prime with beautiful views all around.
