I used Google Earth to look at a trail I wanted to try and noticed that the elevation was posted at the middle bottom of the screen. I was able to look at a huge variety of places to ride. If you trace the trail you can track the elevation gains and losses. I could also estimate the distance a Loop or Detour. I also found out how to get out of a canyon and find a Starbucks. Then you can print out a map of the new playground. H
I searched the threads and couldn't find this info, hopefully it will be helpful.
