Anyone know a way to get a profile of a ride from google? I'm considering adjusting my ride to work a bit - considering a change that will make it slightly longer, and probably a lot hillier.  But from looking at the route on google maps, I can't really tell, even with the terrain layer turned on.

Anyone know of a tool that will graph the profile of a route for me?  

Edit: Ideally, I'd be able to just link the tool to my route on google, and not have to redraw it.

(The routes in question:  Current route, proposed route)
GPS Visualizer will do the job. From this thread: 


  Plan your route as normal in Google Maps.
  Click on "link" above the top right corner of the map.
  Copy the top link.
  
  Go to:  http://www.gpsvisualizer.com/profile_input
  
  Paste the GM link that you copied into the field titled:  "Or provide the URL of data on the Web:"
