My rooommate had watched it live this morning and I watched it on TIVO. He warned me beforehand that it was really bad. I couldn't believe how bad it really was.
Basically, they did not have a camera following the runners on the course. They had some cameras in fixed places where they showed people run by. They also had a helicopter with a camera.
So they tried to broadcast a "race" without actually showing the race. I couldn't believe it. They actually tried to talk about the lead runners (without showing them). But they didn't really have a clue as to what was going on except for the few shots from the helicopter. Finally, you just saw the last 50 m of the race as everyone sprinted in.
Clearly the station had a lot of money to spend on the broadcast (I'm using the helicopter as evidence of this) but they didn't put a camera on the lead vehicle. Somebody screwed up royally.
