Pieter Weening robbed Andreas Kloden of the stage victory with a late surge. Only 0.0002 of a second separated first from second place – a margin to small that it was not visible to the naked eye, not even with the benefit of the photo finish equipment.

it was officially 0.0002s.. which assuming a speed of 50k/hr

d= 50*1000*100*10*0.0002/(60*60*60)=0.05mm

In a sprint, they're a lot faster than 50km/h... the peloton in stage 6 was cruising along on the flats at 47km/h with heartrates under 145 bpm.

Can someone explain to me how they acquired this picture? Unless the camera was moving at the exact same speed as the riders, the ground shouldn't be blurred. If it was a really fast shutter stationary camera, the ground should be sharp and not blurry. I can't imagine them using a camera from above moving at the exact same speed as the riders to get this picture.

somebody explained that in the stage 8 sticky... Apparently they take a vertical line of pixels at the finish line and layer the lines over time to get that photo... hence the horizontal streaks...
