However, the terrain was not the only obstacle. Persistent rain added an extra layer of difficulty, especially on the technical descents, making conditions treacherous and forcing riders to balance aggression with caution.
The wet weather initially dampened attacking ambitions in the peloton, delaying the formation of an early breakaway. It took around thirty minutes before the first serious move developed, with Marc Soler, Mattias Skjelmose, and Ben Healy pushing clear.
Soon after, Peter Oxenberg and Juan Pedro Lopez bridged across, forming a five-man leading group. Still, behind them, the race was far from settled.
Uno- X Mobility emerged as a major protagonist in the peloton, setting a fierce tempo on the climbs. Their aggressive approach was driven by Tobias Halland Johannessen, who had been steadily climbing the general classification throughout the race.
Sitting just outside the top ten at the start of the stage, Johannessen was given some leeway, and his team took full advantage. Their efforts sparked a large chasing group of over thirty riders, including several teammates, which significantly altered the race dynamics.
This second group featured a number of strong and recognizable riders, including Guillaume Martin, Bruno Armirail, Menno Huising, Frank van den Broek, Ramses Debruyne, Emiel Verstrynge, and Brandon Rivera.
However, bridging the gap to the leaders proved difficult, particularly as Soler and Skjelmose pushed hard at the front, clearly aiming to contest the stage victory themselves. Healy later rejoined them, briefly restoring the leading trio.
Meanwhile, in the peloton, the general classification battle intensified on the slopes of the Elosua. Red Bull - BORA - hansgrohe launched a determined offensive, with Florian Lipowitz repeatedly attacking in an effort to put pressure on race leader Paul Seixas.
Despite these efforts, the Frenchman remained composed and unshaken. In a show of strength, Seixas even launched a counterattack near the summit, distancing his rivals and riding clear alone.
His move raised questions about his intentions, especially given the significant gap to the front of the race and the flat sections that followed. Nevertheless, Seixas committed fully to his effort, maintaining a strong pace despite limited team support behind him.
Eventually, with around 20 kilometers remaining, he was caught by a chasing group led by EF Education - EasyPost, effectively neutralizing his solo move but reinforcing his control over the race.
Up ahead, the original breakaway began to lose cohesion just before the final climb. Healy, Soler, and Skjelmose were all reeled in by the chasing group, now heavily influenced by Uno - X Mobility. Soler then shifted roles, working at the front in support of his teammates.
The decisive moment came on the steep slopes of the Asentzio, when Andrew August launched a powerful acceleration. The young INEOS Grenadiers rider quickly distanced all his rivals, showcasing both explosive power and composure beyond his years.
Raul Garcia Pierna attempted to respond but was unable to match August’s pace. From that point on, the outcome seemed inevitable,
as August powered his way to his second professional victory, adding to his earlier success in Valencia.
Behind him, the battle for the remaining podium spots saw Frank van den Broek sprint to third place, while Emiel Verstrynge delivered an impressive performance to finish sixth. Further back, Johannessen’s efforts paid off handsomely.
The Norwegian not only held his ground but made a significant leap in the general classification, moving up to third overall and displacing Primoz Roglic from the podium positions.
As for Paul Seixas, the final climb brought no further threats. With Red Bull - BORA - hansgrohe unable to mount another serious challenge, the French rider safely navigated the closing kilometers to secure his first overall victory in a WorldTour stage race.
It was a composed and mature performance, capping off a week in which he consistently proved to be the strongest and most resilient rider in the field.
Today marked the coming-of-age moment for two hugely talented young riders. Paul Seixas, just 19 years old, whom I had tipped from the very start to win the race, and Andrew August, aged 20.
For the rider from INEOS Grenadiers, this victory could well open the door to more selections in the British team’s line-ups for upcoming races on the calendar.
As for the young Frenchman, this was a clear statement on the road. The top teams in the peloton are already scrambling to secure his signature for the coming years, and rightly so.
Today, he simply swept everything aside, taking home every leader’s jersey, GC, KOM, youth, and sprints. Never before in the history of Itzulia Basque Country has such a feat been achieved.
As for the stage itself, Uno- X Mobility set out with clear intent to attack Red Bull – BORA – hansgrohe and push them off the podium. They partially achieved their goal, snatching third place from Primoz Roglic and coming within seconds of dislodging Florian Lipowitz from second overall.
The Scandinavian outfit may not have the financial power to sign the biggest stars, but they ride with heart, passion, grit, and determination. And Halland, this season, has been a remarkably consistent rider, showing significant growth, with his performances on the road becoming increasingly frequent.
Final word for UAE Team Emirates - XRG and Team Visma | Lease a Bike. Emirates saw Del Toro abandon after a crash, while Soler cracked on the final climb of the day, when he only needed to take two points to secure the KOM classification overall.
And Visma… did anyone actually see them? Were they even in Spain? Because if they were, I certainly didn’t notice them. Two of the most powerful teams in the peloton, two complete failures.
A very strange day. Paul Seixas is comically superior to the rest of the field in this race at this point in time, and that is why he managed to secure the overall win today. Because for a regular rider, it could well have been lost today.
With the stage starting off with a climb, you know attacks will come. There were conflicting reports on whether Matthew Riccitello was in front or not, but from the moment Paul Seixas attacked to the moment he was caught by the group of his rivals, he was alone the whole time.
Decathlon did not try to control the breakaway and let DOZENS of riders go up the road, including GC threats, and either put only 1 rider who had no utility later on in it, or had no-one, which I cannot understand for my life.
It is horrible tactics and if the Frenchman hadn't won minutes over everyone else over the whole week with attacks where he simply was unmatched, then he could've lost the race.
Because from the moment the race began being pushed in the peloton, he was isolated within minutes. Then he attacked and was alone in flat roads against a peloton out front and a group of his rivals behind.
A situation where only a Pogacar could still make it work. Seixas was close, but there's times where you can only defy logic so far. It was a bizarre day of racing, which is entertaining, but I can't say I understand what was behind many decisions from the GC group.
Luck rewards the brave then, in this case it didn't take much bravery, but Uno-X placing 5 riders including their leader in the breakaway is exactly the kind of tactics I look to see smaller teams do.
They get rewarded heavily with a spot on the final podium after a massive collective effort, and I hope it encourages other teams to do the same in the future.
The final stage of the 2026 Itzulia Basque Country sent a very clear message: a double success, both as a team and individually, on an incredibly tough day that rewarded ambition.
On the one hand, Andrew August’s victory confirms INEOS Grenadiers’ excellent form. It was not an opportunistic win, but one built on courage: a long-range attack, a breakaway from the leading group and a finish at just the right moment.
He read the race perfectly and, above all, managed the head-to-head battle with Raúl García Pierna, whom he eventually dropped at the most decisive moment. It is the kind of victory that speaks of strength… but also of competitive maturity.
But the big name of the day - and of the week - is Paul Seixas. Beyond ‘defending’ the general classification, what he did was something far more significant: riding without fear.
In a chaotic, rain-soaked stage with multiple open scenarios, he did not limit himself to controlling the race, but even allowed himself to attack and get involved in dangerous moves. That attitude, unusual for someone so young and the leader of a WorldTour tour, is what truly elevates his victory.
Because winning the Itzulia isn’t just a matter of legs: it’s a tactical, explosive and highly treacherous race. And Seixas has dominated it from day one, capping it off with an active defence reminiscent of the great stage racers in their prime.
In summary: INEOS continues to build a case for itself as a solid, winning team. Andrew August has established himself as a rider to watch very closely. And Paul Seixas isn’t just winning… he’s starting to establish a new pecking order in the peloton.
