The gap remained close to inside three minutes as Pogacar reached the final climb. Even with the chasers beginning to claw back seconds on La Comella, there was no meaningful pursuit left: Pogacar was riding towards a stage win and a general classification advantage that, barring exceptional circumstances, already looked decisive for the Vuelta as a whole.
Decathlon set the stage for Pogacar's attack
The 104.8-kilometre stage had been aggressive from the opening kilometres, with the race climbing almost immediately onto the Port d'Envalira. Repeated attacks produced a large and dangerous breakaway, while UAE Team Emirates – XRG initially controlled behind before Decathlon CMA CGM Team took over the pace-setting for Gall.
Sander De Pestel drove hard on the long first-category climb, rapidly reducing both the break's advantage and the size of the peloton. Wout van Aert and Matthew Brennan were among those eventually dropped from the move, while Santiago Buitrago was one of the more notable riders losing contact from the main field.
Lorenzo Fortunato beat Paul Double to the maximum mountains points at the top of Envalira, but the remaining attackers carried only a small advantage onto the long descent and were soon swept up. Decathlon continued to press towards the Collada de Beixalis, having already split the race into several groups before the main favourites reached the steepest climb of the day.
Tadej Pogacar in action on stage 4 at the 2026 Vuelta a Espana
Jay Vine briefly took over at the front for Pogacar before Decathlon again lifted the pace. On gradients reaching 16 per cent, Pogacar then launched the attack that transformed the stage and, potentially, the entire Vuelta.
Gall dug deep to follow, but quickly recognised the effort was unsustainable and allowed Pogacar to ride away. The Austrian was eventually reabsorbed by a chase containing the rest of the major GC contenders, while Pogacar continued to increase his advantage without any obvious sign of slowing.
By the summit of Beixalis, the Slovenian had already stretched the gap to around 1:40. Carapaz led the chasers over the top behind him, while Pogacar added further points to his mountains tally before collecting the intermediate sprint in Ordino as well.
The chase remained sizeable initially, with most of the main GC contenders still together as Netcompany INEOS helped control the pursuit for Onley. Mikel Landa was among those unable to maintain contact as the pace rose on the lower slopes of Ordino.
Gall then accelerated again, with Onley the only rider immediately able to follow. Roglic responded shortly afterwards and bridged across, before Kuss and Mas also made the junction to form a five-man group containing some of the strongest climbers in the race.
Even that selection made little impression on Pogacar. By the end of the Coll d'Ordino, the Slovenian was already around three minutes clear of the strongest GC chasers.
The descent brought the main chase back together before La Comella, but by then the riders behind were effectively fighting among themselves for the minor places. Pogacar still carried an advantage of around three minutes onto the final climb, where Gall tried once more to force a selection while Skjelmose slipped away from the group.
Pogacar crested La Comella with the stage already his barring disaster and threw himself into the final descent towards Andorra la Vella. What had started as the first opportunity to measure him against his main rivals had instead become something far more decisive: the contest for red had been reduced to a formality before the Vuelta had even reached the end of its fourth stage.
