If you get Motionbased loaded to your PC you get a better quality of mapping & some fancy graphs where you can analyse your speed, distance, heart raet etc, Also exports straight to their server so if your PC crashes you have not lost your work outs, ALternativeley use Sportsim, same sort of thing, good on screen maps with overlayering of similar runs that can be played at the same time. I Use all three & it does help you to pace yourself as you get to know the routes & can scan through your worksout to see what you were doing at those points. If you want to be fancy Export to Google Earth to get a full on satelitte map. I had a 301 which worked on all programms & have had a 205 for a month know & its just the same. You should be able to set your Virtual Partner on a past run also, not sure how this works or even if i can programme the unit to do it.
