my best guess would be panning with multiple flashes. ok i :dunno:
This is a indoor track event with 4 cyclists...
so this is one shot, with a slightly longer shutter speed to induce some motion into the picture..
This seems to be the best explanation, but it doesn't explains for the sharp shadows.Looks like a normal pan shoot with a slightly longer shutter speed . Existing lighting in a typical velodrome track. No multi flashes is used. This is a 4 men time trial blistering at a speed of 60mph. The slight blur especially the rear rider is he completing the "hand-over" He was in the front adn then he cycles to the right side of the second rider and he slow just enough that he now gets to the back and become the rear 4th man. This is call drafting...to lessen the wind resistance as a team cutting around this tight track. Sometime it is not the photography you need to know to see how a shot is made. You have to know the sport.

I'm curious about the distortion of the light green strip on the inside of the track.
I also noticed the right hand portion of the photo, wonder why it was achieved. Maybe PS this one? :dunno:
