Today's winners: (1) Simon Yates, for a brilliant and gutsy assault on the final climb and descent, (2) Wout van Aert, without whom Roglic would have lost the yellow jersey, (3) hypothermia, for doing nasty things to all the riders, some worse than others, (4) Roglic, for hanging tough on a day when he was clearly not at his best--looked to be suffering from hypothermia worse than the best riders on the day.
