The other day, Google Maps added quick facts to maps in the Google Maps search results box, and I assume, as part of that, came these new biking directions elevation profiles.
Now if you do a bike route in Google Maps, Google will show you the elevation profiles of the route you selected. This is so you can either avoid or target routes will lots of hills and slopes.
Here is a picture:
Google said "Embrace the climb or avoid that hill with bike directions + new elevation profiles on #GoogleMaps for desktop."
