San Francisco is one of the world's most visited cities, and its iconic Golden Gate Bridge, sourdough bread, lung-bursting hills and cable cars make it just as thrilling for cyclists of all abilities.

With a moderate climate year round, little rain and plenty of sunshine, the Bay Area, including lower Marin County, San Francisco, the East Bay and Peninsula, thousands of great bike riding miles are available for every skill level. From beginner to intermediate, everyone has access to hundreds of parks, bike lanes, bike paths and incredible vistas with the Pacific Ocean, San Francisco Bay and the Santa Cruz Mountains as the constant back drop wherever one looks.

The view from the handlebars and saddle include the Bay Area's many independent coffee shops, including the West Coast's first Italian espresso bar, Caffe Treiste in North Beach, all the way down to Red Rock Coffee in downtown Mountain View, home of Google and Mozilla. Individuals, couples and families are always pampered and spoiled by the fine cuisine available in nearly every neighborhood.

Author Gary Boulanger is riding every planned route, using a Garmin GPS unit specific for data and mapping. The final book will grade each ride from one to five stars in difficulty, including full color maps and hill profiles. Interesting and historic facts will be peppered throughout each ride, including directions on how to get there, what to bring, how to dress, and where to stop to take pictures or enjoy the local food and drink.
