Enclosed you can find an example of what this free program can do: http://www.gruesink.demon.nl/appletGPSAR/gpsar.html http://www.gruesink.demon.nl/appletGPSAR/gpsar.html

When you select play it plays, when you select 'grafieken' and the VMG you can see a result.

The track is from the Zandvoort race btw, but not all of the gps recorded the entire race.

Even if I can get my data in this program I would know how to interpret or compare different results...
