A 5-6 men breakaway of very average riders to finish 10 minutes ahead of the 70-men peloton.
I hope you are not right.
I think the prospect of mountains getting cancelled, and having seen the first Corona case in the peloton, a lot of GC riders will think, that tomorrows stage might get crucial, even if the route doesn't quite read that way.
Add to that, that we will see a lot of descending, on small, windy Italian roads full of fall leaves, with rain being forecast for the second half of the stage.
Oh, and to add to the potential drama, Fuglsang was angry Trek pulled when he had a technical today, and told Nibali to be careful when to take a piss the rest of the Giro, so both Astana and Trek are clearly hyped up and ready to stick it to each other..... if one of them has a technical or comes off, all hell might break lose..... Fuglsang is better in the rain, Nibali is better on descents.
So tomorrow could become epic, if the stars align...... but then you are right, that the stage profile itself looks like an exercise in boredom, in terms of GC action, and that is most probable.
