Carapaz wins stage 14 in Vuelta, Roglic reduces gap to Evenepoel
The Ecuadorian climber was the only rider from the breakaway who managed to stay ahead of Miguel Angel Lopez (Astana-Qazaqstan), who came second after finishing eight seconds behind Carapaz.
Saturday's stage win came two days after Carapaz attacked to win stage 12.
"We knew that today was a very important stage for us, that we could repeat what we did the other day," Carapaz said. "The truth is that it took a long time to get away, but in the end I was there at the right time.
"I was able to attack, I went alone and then my breakaway companions joined me. They came with me and then there was a pretty good collaboration.
"At the end, I knew the climb very well. So, I tried to set my own pace, without losing hope, because I knew it was very hard. It has been a great stage, quite important for my record and for me. Above all, it gives a lot of morale."
Jumbo-Visma rider Roglic came third with a gap of 48 seconds to Quick-Step Alpha Vinyl's Evenepoel on the line.
Evenepoel retains the red jersey, 1:49 ahead of Roglic and 2:43 clear of Enric Mas (Movistar) ahead of another big mountain stage in Andalusia on Sunday.
