Just as when I’m getting the hang of using the A-GPS of my Nokia 5800, the tracker site is closing!  Here’s the excerpt from http://sportstracker.nokia.com/:

After two and a half years of operation, the Nokia Sports Tracker beta service will close as of June 30, 2010.  Thanks to all of you exercise enthusiasts who used the service and contributed valuable feedback to its improvement.

We want you to stay active.  You can keep tracking workouts through a new, non-Nokia service provided by Sports Tracking Technologies available for free in the Ovi Store.  The new service is open for registrations at sports-tracker.com, and you’ll even be able import your workout history from Nokia Sports Tracker until August 31, 2010.

There you go, you still have some time to transfer your Nokia Sports Tracker data to the new Sports Tracker website which is now accepting pre-registration and will be launching soon.  As an alternative you may simply export your data from your phone as a GPX file and import it to third-party sites like Garmin Connect which I use to store all my Garmin data (Garmin not required to signup), albeit would be exported as one lump of data losing all lap details.
