QuickRoute is a program that takes a GPX file and a map and makes them useful. In the latest release of QuickRoute you are able to compare yourself (compare routes or race against) others using the capabilities of Google Earth.

Jordan has posted both the jpg and the QR files. You can see your jpg without downloading QR.
Last month's ONA has an article on how to use QR for coaching that Jon and I put together. I'll try and get it posted on the website.
There are also some .kmz (Google Earth 5.0) files that is the comparing feature.
