I like the idea though I probably wouldn't use it myself. I don't typically do the same route the exact same way day after day. Because of that, seeing a ghost on the map wouldn't be useful. I also am not looking at the map when I'm running/biking. One feature I would use is based on distance/time rather than position. So if I run a 10 minute mile yesterday and I run a 10:24 minute mile today, I would like to know that I was 24 seconds slower today.
