BUT WHY DOES IT MATTER? Seriously, why does it matter if they want to race the stage or not? Riders are selfish. If I couldn't climb and was 3 hours down and had no teammates who could do well, I would be all for a shortened stage Im sure. Get me out of this misery, its freaking cold, the climbs are hard, the stage is long.
But it shouldn't matter one single bit. They signed up for this, its their job, and the passes were PERFECTLY passable. Completely fine. That should ALWAYS be end of the story.
Vegni should have told them to shut their arses, hop on their bikes and race the stage. If something comes up that suddenly makes the race impassable (hint - its not rain and cold), then cancel them. But dont freaking cancel them cause some wussy ass riders dont wanna ride and the slim possibility of sudden snowstorms etc. Its perfectly legal to reevaluate the route once the race is underway and bad things happens on the passes, but if this is the way to go about things, we will never ever witness these truly great mountain stages and them im not watching anymore of this sport apart from Roubaix and Flanders.
