One of the biggest windsurfing race. 700 competitors.
And here's some GPS tracks from it too.
there are 3 races the second and third are the fastest.
The applet takes bout 30sec's to load all tracks up so be patient.
Once loaded press the ">" play forward button at the top left. You
can adjust speed of playback with the slider marked speed to the right
of that button. Over on the right check off either footprints or
neighborhood ( on right hand side just under "Trajectories") to remove
track lines...and enjoy.
The second or third race has a decent battle between Antoine Albeau
and Anders Bringdal.
