I've owned a vacation home in Guerneville for over 14 years. I would recommend you look for a home located off of Armstrong Woods Road if you want to be able to go long distances for a run. Although there are many nice neighborhoods around Guerneville, most do not have sidewalks and narrow streets make it unsafe for pedestrians. Armstrong Woods Road (for the most part) has a wide shoulder/bike lane and it leads into the park which contains many roads and trails perfect for a run with or without a stroller. The areas off of Armstrong Woods Rd also have more sun and there's less traffic so if you wanted to just stay in your neighborhood for your run you could do so safely. My home is located off of Neeley Rd which is a lovely area but to get into town without a car you need to walk on Neeley which scare me - cars whiz by too fast and the shoulder is narrow to non existant at best. Good luck in your search!
