Vuelta a España | September 3 Stage 12: Jakob Omrzel Conquers Calar Alto as Enric Mas Extends His Overall Lead

On September 3, 2026, the Vuelta a España completed Stage 12, one of the most demanding mountain stages of the second week.
The stage started in Vera and finished at Calar Alto, covering 166.6 kilometers. Classified as a mountain stage, the route featured several challenging climbs, including Alto del Cabecico, Alto de Cóbdar, Collado Garcia, and the Category 1 Alto de Velefique before the final ascent to Calar Alto.
The decisive climb was the summit finish at Calar Alto, which rises to 2,153 meters above sea level. The final climb is approximately 16.9 kilometers long with an average gradient of 5.6%, making it a major test for both the breakaway riders and the general classification contenders.
After a fiercely contested battle, 20-year-old Slovenian rider Jakob Omrzel of Bahrain Victorious claimed a remarkable stage victory after making the decisive move during the final climb.
Behind him, Enric Mas of Movistar Team once again proved to be the strongest rider among the general classification contenders, extending his lead in the red jersey competition.

Omrzel Makes History with a Breakaway Victory
The outcome of Stage 12 was largely shaped by an early breakaway.
After numerous attacks during the opening kilometers, a large group of riders eventually established a significant advantage over the peloton.
Among the riders in the breakaway were several strong climbers, including Jakob Omrzel, Pello Bilbao, Santiago Buitrago, Raúl García Pierna, Pablo Castrillo, Luke Tuckwell and Léo Bisiaux.
As the breakaway contained riders capable of influencing the overall classification, the main group continued to monitor the gap. However, the leaders maintained their advantage as the race entered the most difficult part of the course.
The decisive battle began on the final climb.
Omrzel and several other riders initially remained together, but the young Slovenian launched his decisive attack during the approach to Calar Alto. He then rode the final kilometers alone, gradually increasing his advantage over the chasing riders.
Despite the relentless pace behind him, Omrzel remained composed and maintained his lead all the way to the summit.
The 20-year-old crossed the finish line first to claim the biggest victory of his young career and one of the most impressive performances of the 2026 Vuelta.

Urko Berrade Finishes Second as Buitrago Takes Third
Omrzel's closest challenger was Urko Berrade Fernández of Kern Pharma, who finished second.
Berrade crossed the finish line 1 minute and 56 seconds behind the winner, while Santiago Buitrago of Bahrain Victorious completed the podium in third place, 2 minutes and 13 seconds behind Omrzel.

The result also highlighted the strength of Bahrain Victorious, with two riders finishing inside the top three.

Enric Mas Attacks Again and Strengthens the Red Jersey
While Omrzel took the stage victory, the biggest development in the general classification came from Enric Mas.
The Movistar leader did not simply defend his advantage. Instead, he launched a powerful attack with roughly 12–13 kilometers remaining, during the final climb toward Calar Alto.
Mas quickly opened a gap over his main rivals and showed once again that he was currently the strongest GC rider in the race.
His Movistar teammates also played an important role in controlling the race and supporting their leader. Raúl García Pierna, who had been part of the breakaway, was able to provide valuable assistance to Mas at a crucial moment.
Mas eventually finished 27 seconds ahead of key rivals Primož Roglič and Félix Gall, adding another significant advantage to his overall lead.
After Stage 12, Mas now leads Roglič by 1 minute and 45 seconds, while Félix Gall sits third at 2 minutes and 6 seconds.

Roglič and Gall Continue the Fight, but Mas Holds the Advantage
The Stage 12 result further strengthened Mas's position at the top of the general classification.
General Classification After Stage 12

Richard Carapaz moved into fourth overall after Oscar Onley lost significant time, while Omrzel's exceptional ride lifted him from 10th to sixth overall.
The young Slovenian's rise adds another interesting dimension to the GC battle. Although Mas remains clearly in control, Omrzel has now demonstrated that he can compete with the strongest riders in the mountains.

Omrzel Emerges as One of the Biggest Surprises of the Vuelta
The significance of Omrzel's performance goes far beyond a single stage victory.
At just 20 years old, the Slovenian rider delivered a breakthrough performance in his first Grand Tour. He not only made it into the breakaway but also managed to distance experienced climbers on the final ascent and complete the final kilometers alone.
His victory at Calar Alto has immediately established him as one of the young riders to watch during the remainder of the Vuelta.
Omrzel's performance was also particularly impressive because he was racing against riders with considerably more Grand Tour experience. His ability to remain calm under pressure and maintain a high climbing pace throughout the final ascent demonstrated his potential at the highest level of professional cycling.
For Bahrain Victorious, the result was especially encouraging. With Omrzel winning the stage and Buitrago finishing third, the team demonstrated considerable strength on one of the toughest mountain stages of the race.

Wout van Aert Continues His Fight for Points and Climbing Honors
The battle for the secondary classifications also remained intense on Stage 12.
Wout van Aert was active in the breakaway and continued to collect points during the stage. His aggressive approach showed that he remains committed to defending his position in the points classification while also taking opportunities in the mountain classification.
According to the official race information, van Aert continued to hold the points jersey, while Santiago Buitrago remained a major contender in the climbers' classification.
With the race now entering an increasingly demanding phase, the competition for the red, green and climbing jerseys is becoming more intense with every mountain stage.

The GC Battle Takes on a New Shape
The withdrawal of Tadej Pogačar earlier in the race has significantly changed the overall classification battle.
With one of the pre-race favorites no longer in contention, Enric Mas has emerged as the central figure in the fight for the overall victory.
Mas has increasingly demonstrated an aggressive racing style, particularly in the mountains. His attack on Calar Alto was another clear indication that he is not simply trying to protect the red jersey but is actively looking to increase his advantage.
Roglič remains his closest challenger, while Gall and Carapaz are still within striking distance. Meanwhile, Omrzel's dramatic rise into sixth overall has added a new name to the GC conversation.
With several important mountain stages and an individual time trial still ahead, the final outcome remains far from decided.

Stage 13 Preview: Almuñécar to Loja
The Vuelta will continue on September 4 with Stage 13, running from Almuñécar to Loja.
The stage covers approximately 192.8 kilometers and is classified as a medium-mountain stage. Unlike Stage 12, the route does not finish with a summit arrival, but the demanding terrain could still provide opportunities for breakaway riders and attackers.
After the intense battle at Calar Alto, some GC teams may choose a more controlled approach, while riders looking for a stage victory are likely to target the breakaway.
For Movistar Team, the priority will once again be protecting Enric Mas and controlling the race. Roglič, Gall and Carapaz, meanwhile, will be looking for opportunities to reduce the gap.
Omrzel will also attract considerably more attention after his breakthrough victory. Other teams will now be much more aware of his ability to attack in the mountains.

Conclusion
Stage 12 of the 2026 Vuelta a España produced a dramatic combination of a breakthrough victory and another major GC statement.
Jakob Omrzel delivered the biggest win of his young career by conquering Calar Alto from the breakaway, while Enric Mas strengthened his position at the top of the general classification with another powerful attack.
Mas now leads Primož Roglič by 1 minute and 45 seconds, while Félix Gall remains third overall. At the same time, Omrzel's victory has moved him into sixth place and established him as one of the most exciting young riders of this year's race.
With the Vuelta entering another crucial sequence of stages, the battle between Mas, Roglič, Gall, Carapaz and the emerging Omrzel is becoming increasingly compelling.
The road to the final victory in Madrid remains open, but after Calar Alto, Enric Mas has clearly strengthened his position as the rider to beat.
