A nice feature of Google maps:

  • Take a GPS log file
  • Convert it into the .KML format used by Google Earth.

  • Go to Google Maps, and search for the URL of the .KML file
You'll get a nice map of your track. And you'll even get information about how to link to it and how to embed it in your site. Here's a section of the route I walked today, for example:
