Etna to the top is the kind of crazy dumb stupid *** I want in a one day type race. Feel that would be a much better place for such a thing. 4 man teams, make it WT. Do set it in whatever week after the Tour. More climbs suited to this than just the Etna.This sounds extreme and all but it's really most of all of a logistical nightmare. In terms of difficulty and importance for the gc there would have been bigger mountain time trials in the past. It's just that Etna time trial up to almost 3000 meters on gravel roads sounds ridiculously cool.
And of course so early in the race it would really force the riders to not arrive undercooked
