How did Enric Mas win stage 9 on Alto de Aitana?

Stage 9 ran from Villajoyosa to the Costa Blanca summit of Alto de Aitana on August 30, 2026. Tadej Pogačar's exit cast a shadow over the morning, but once racing began the peloton showed no sentimentality on terrain familiar from countless training camps.

A six-rider breakaway escaped early, later swelling as Grand Tour veterans joined the front. Pavel Sivakov struck out alone 10km from the top after Decathlon-CMA CGM took control of the peloton on the long final climb. Felix Gall attacked on the flattest section, making it easy for rivals to follow.

With 4km remaining, Enric Mas made his first and only move of the day. Only Oscar Onley could match the acceleration. Primož Roglič chased but could not complete the catch, finishing third 18 seconds back. Mas held the front through the steepest section and fended off Onley's late challenge before the line.

Why does Oscar Onley's second place matter for the Vuelta?

Oscar Onley confirmed he is the best of the rest behind Mas on the queen stage of the opening week. The Netcompany Ineos rider tracked the Spaniard's decisive attack and stayed in contact through the punishing final kilometres, earning a mountaintop second without surrendering time to the race leader.

Onley's performance also reshuffled the fight for the podium. He gained 18 seconds on Felix Gall, who finished fourth after his team's relentless pacing. Gall retained third overall, but the margin among the leaders is razor-thin. For more on how performance data is reshaping endurance sport, see our Future Tech & AI Wonders coverage.

Who lost ground on the Vuelta's first mountain finish?

Sepp Kuss was the day's biggest loser in the general classification, slipping from fourth to seventh and falling 4'09" behind the red jersey. Gall's ill-timed attack on the final climb hurt his own chances despite Decathlon's impressive work setting a furious tempo that decimated the peloton to roughly 15 riders.

Richard Carapaz attacked over the top in pursuit of Sivakov but could not sustain the effort. Sivakov, who had led alone with five minutes' advantage at the foot of the climb, was caught before the decisive moves among the favourites unfolded.

What happens next in the 2026 Vuelta a España?

The race reaches its first rest day with the overall standings tighter than many expected after Pogačar's departure. Mas leads, but Roglič sits 18 seconds back in third and Gall remains within striking distance despite a frustrating day. Onley sits between them, poised to challenge again when the road turns upward.

Decathlon sports director Leo Bisiaux said the team would try again in the second week, insisting the red jersey is not so far and that nothing is over. Roglič sounded content with third, telling reporters he was super happy despite doing little work on the climb. Full stage coverage is available from TNT Sports.
