Google has quietly added elevation data to bike routes in its Maps service, providing better intel for intrepid cyclists. The feature, which launched Friday, seems to work for much of the U.S. and Canada. Google says Maps already factored in elevation when determining routes for cyclists, but until now the elevation data wasn’t made easily visible. Type in an origin and destination for biking, and the service now displays a graphical representation of the route’s elevation. Drag the cursor along the chosen route and the graphic shows the elevation changes at any given point. The total elevation change is also displayed.
