Ah - the Garmin application mygarminconnect.com it hooks up to my GPS watch. HOWEVER, the best way to map routes without this, and what I use when my watch is dead is www.gmap-pedometer.com
Does not have any advertisements and gives you elevation/rough calculations of calories burned. It is a hack of google maps, and it is pretty damn precise.
Also though, if you want a GPS watch, REI was just having a sale on the forerunner 110 (the watch I use) for 135. Worth a look.
