There will probably be too many human interest stories. At least they won't be about hobby joggers or mid course weddings or proposals (but who knows).
They for sure will go to break at the precise moment a move is made.
They will focus exclusively on the lead pack, and once it splinters forget about getting any updates on any other runners.
Feed will be choppy, if not lost entirely, for long stretches.
Commentating will suck.
