About the course
- For 2027 the Medio, Gran and Growler routes all go out to the Pacific coast again.
- The long routes climb narrow, steep back roads onto exposed ridges before dropping to the ocean, then climb back inland.
- Weather: Late April in Sonoma County is usually mild inland, but mornings start cold, and the ridges and the coast can be much cooler, foggy and windy than Windsor. Rain is still possible. The weather here is for Windsor; expect it colder and windier at the coast.
