Ladies chasing derny's

As a warming up for the great race of this evening: a ladies run, behind pacesettetters; in this case these are called "derny's.
I was triggered by an article in our newspaper this morning so I searched for a good spot at the other side of the canal.
I tried to bring some speed in it by panning the camera on a fairly low shutterspeed.

Better in LARGE....

Here is another one in the Almost Blip.
