If your into running, walking etc you may have come across this site, I think its fantastic. http://www.gmap-pedometer.com/
It enables you to plot your run, walk or whatever and gives you the distance travelled and shows you the elevation of your route. Once your done you can save the url, like this ( http://www.gmap-pedometer.com/?r=1658414 ) which was what I did tonight, and keep as bookmarks!
Enjoy!
