The 50 routes span a large geographical range throughout the Bay Area. Each card has a detailed map and excellent written instructions that are sure to keep you on route.
The cards are color coded - brown cards are off-road, green cards are paved and blue cards indicate a waterside route. Within these three categories, riders can select from a great variety of routes: long or short, hilled or flat, easy to difficult. You can travel on-road, over creeks, through mountains, around reservoirs, down hills and along the sea. Skill levels range from casual to expert.
These are a great idea! everything you need but not much more - the map with only the roads you need, the elevation profile, brief route description and mileage log/legend that indicates turns, climbs, and even where to get water or food (you wouldn't get the info on locations of water fountains, food markets or scenic outlooks from regular maps).
The cards fit easily in the jersey backpocket and are sweatproof. Easy to glance at/read while riding. Must have!
