But depending of his position more early in the climb. At 1 km of the top, he probably was in twentieth position. The riders before him had to allow a gap. Evenepoel had to close the gap.... and then Pogacar jumped. So, the first seconds Evenepoel was not able to react, because his legs exploded. Later, it was difficult to pass other riders, due to the narrow road at the end of the climb and the public. Considering the circumstances, he did well.According to Strava Remco lost 11s to Pog on the San Luca climb (5:06 vs 5:17).
I don't think he would have been able to stay in the wheel Of Poga and Vingegaard after the attack. But that he could have come back at the end of the descent, not having Carapaz in his wheel. But the result would have been almost the same. Collaborative they could have taken a few seconds extra of Roglic, Rodriguez etc.
