As stated in the Basic Rules there are several software tools available to analyse your speedstatistics:

• GPS Action Replay  (www.gpsactionreplay.com)
• GPS Results (www.gps-speed.com)
• GPS Speedreader (https://ecwindfest.org/GPS/GPSSpeedreader.html)

We have noticed that there are still some members who are using out-dated software versions of GPS-Results & GPS Action Replay. This could lead to inconsistencies in both Google Maps Overlay (accessible for all members in all sessions) and Full Track Mapping (Premium Members). Every members is responsible to keep their own software up-to-date.  Please frequently check the websites of the software vendors and make sure that you use the latest version. When you use older (not supported) versions of the software the upload of your track will be blocked.

When you use the “Upload Track” feature from the gps-speedsurfing.com website you don’t have to take any additional actions, this software is updated automatically.
