"Nokia Sports Tracker" is a GPS based activity tracker that runs on S60 smartphones.

When running, walking, cycling or skiing, information like speed, distance and time are automatically stored to your training diary. You can also add your own custom activities.

To be able to use application for real, you need Nokia S60 3.0 or 3.1 phone with Bluetooth GPS device or Nokia S60 3.0 or 3.1 phone with integrated GPS.
 

 
I've recently got a Nokia N73 and the Sports Tracker application is perfect for recording my training for the London Marathon in 2008. With this particular smartphone, I will need a separate Bluetooth GPS Receiver. (they are usually only the size of a matchbox)

The Sports Tracker Application looks like a great way to compile statistics for sporting activities.

A great feature of the application is that you can export your training or race routes to Google Earth and see where you've been.

If you want to see your recorded track on the map, you can export the workout to a file in KML format (in workout summary choose Options->Save as->Export to Google Earth) that can be visualized using 3rd party applications, such as "Google Earth". The image below shows how a generated KML file can be viewed in a web browser:
