Evenepoel performed well today, given the terrible circumstances (but the same for everybody) and the fact those are his first days of competition. But, as I wrote yesterday, the fact that he rode on a high rear the day before, in the uphills, wasn't a good sign. And he looked terrible in the final. Sunken eyes, dark bags under the eyes. But he showed character and drove wisely. If he can recover in the next, flat stage, he could maybe survive the next mountainstage at thursday. If it doesn't rain all day. He clearly has problems with that.
I also think he and his coach/fysical coach made a mistake by let him lose too much weight. In the Tour, where it is often hot, that's OK. But in Italy, the first half of May, it's often rainy and cold, especially in the mountains.
