Marathon Course Video

I was expecting something different than this video, maybe because it was described as a "3D view of the marathon course." Nevertheless, it's interesting to watch the course get traced (but painful to imagine how far it really is!) throughout the DC area. I'd love to see a Google maps overlay, or maybe a MapMyRun track... hmm, maybe I should check and see if someone has done one already! If they haven't, maybe I will make the time to do it... Or not... :)
