Enthusiasts have had plenty to cheer about with the convergence of electronics and bicycling over the years, from bikes that pedal themselves to the various devices and apps that assist them with their training. And for those of us who just want to get from one place to another? Google Maps has added bicycling directions to its walking, car, and public transport options -- with travel times calculated to include things like the number of hills and fatigue over time. But that ain't all! The company has also partnered with Rails-to-Trails to provide information on bike trails in more than 150 cities. According to Google, thousands of miles of trails in the US have already been added to the map, with more to come. For the time being, however, only those planning trips in their home or office need apply: while available on the web, those using a Google Maps smartphone app are being excluded for the time being. So much for "mobile first," guys. Video after the break.
