Olympic cycling

Just watching the cycling. What the hell is going on? We seem to have two groups, but they keep switching between the two with little comment. The commentators themselves have stated they're getting no information about the race order.

Oh and the "Peloton" is coming up, what the hell is that?

How much of a bungle is this? We see an "attack" by one of the cyclists and the commentators state "we don't know which group he was in".

Total shambles from those in charge of providing the coverage.
