Evenepoel was 48 seconds faster than second-place Primoz Roglic, taking his general classification lead over the three-time defending champion to 2 minutes, 41 seconds with 11 stages left.
“That’s a big surprise,” Evenepoel said when told of his gap to his rival from team Jumbo-Visma. “Now we’re going to fight and we’re going to try to win this Vuelta. The pressure is off. I won a stage. Now the whole team is super confident. Everybody is performing so well. Now we just have to fight to keep this jersey and take it home.”
Evenepoel is the first rider to beat Roglic in an individual time trial in the Vuelta. He is also the first Belgian to win an individual time trial in the Vuelta since Fons De Wolf in Valladolid in 1979.
Enric Mas, the Spaniard from team Movistar, dropped from second to third in the general classification, sitting more than three minutes off the lead. Fellow Spaniard Carlos Rodriguez was nearly four minutes behind Evenepoel in fourth place.
