the video appears to be from one of the warm-up sessions before the actual racing started, showing riders desending* from near the top of the climb. during this weekend's circuit race on the same parcours, i predict that the faster categories will be winding out at better than 75 kilometers/hour on this same section.
for those of you who haven't seen top level road racing before, this 4-day stage race will present many great opportunities to do so.
the chicane through the gate looks kind of sketchy to me, hopefully the promoters put up a few strategically placed hay bales for safety's sake.
*note to aspiring young or novice riders: observe the rider in the blue kit in front of the camera... not holding a steady line on the wheel of the rider in front of her, is she? several unpredictable, side-to-side movements going on there.
the rider in front of her is ready for Moto GP with his knees hanging out in the wind like that, exaggerating just a little too much for the corners being negotiated and how fast (or slow, rather) they are actually going.

the moral of this story is: either trust the rider in front of you to be solid and predictable (so that you may ride in a similar manner) or be the rider in front.
