Vuelta a España: This is where the battle for the red jersey will be decided

The riders have now had their first rest day, and 2026 Vuelta a España is slowly but surely entering its decisive phase. Following Tadej Pogačar’s crash and subsequent withdrawal, there is no longer a clear favourite for the Red Jersey. Instead, several riders are battling it out on equal terms for the overall victory, which is why every mistake and every dip in form could have serious consequences. Five stages in particular stand out in the remaining route. They are likely to decide who ends up at the top of the leaderboard in Granada.

Endurance test at Calar Alto during the Vuelta

The first real key stage after the rest day comes on the twelfth stage. The focus is on the Alto de Velefique and the final climb up to Calar Alto.

The final 40 kilometres are mostly uphill. Although the average gradients of 7.2 per cent on the Velefique and 5.6 per cent on the Calar Alto may seem moderate at first glance, it is the length of these climbs that makes this stage of the Vuelta so challenging. More than 30 kilometres of categorised climbs await the riders here at the end of the stage.

The short descent between the two mountains also offers little opportunity to catch one’s breath, as only a portion of the altitude gained previously is lost. Maintaining a steady rhythm is likely to be particularly challenging. Unlike on long, steady Alpine passes, the gradient varies constantly. Anyone who loses their rhythm here could quickly lose a lot of time. Above all, it requires stamina and the ability to ride consistently at the limit of one’s capacity over a long period.

The first steep climb to the summit

Two days later, the 14th stage – finishing at the summit of the Sierra de La Pandera – presents the next challenge for the general classification contenders. The focus will be on the 12-kilometre-long final climb, with an average gradient of 7.2 per cent. However, the figures alone do not tell the whole story. Time and again, there are sections with double-digit gradients that will demand everything from the riders.

Precisely because the outcome will be decided solely by this final climb, we could see a clearer picture emerge in the general classification for the first time. Whoever puts in a strong performance on the Sierra de La Pandera will secure an excellent starting position for the decisive final week of the race.

The time trial marks the start of the final stage

Following the second rest day, the programme initially features a few less spectacular stages. Major attacks by the favourites for the general classification are unlikely. That changes abruptly on the 18th stage.

The 32.3-kilometre individual time trial marks the start of the Vuelta’s final stage. Whilst the course is not entirely flat and features a few minor undulations, it is far from being a mountain time trial. Good time trialists will therefore have a clear advantage.

The time gaps could be significant here. Over a distance of more than 32 kilometres, riders could gain or lose time by several minutes. Whilst riders such as Felix Gall or Enric Mas will likely be focusing primarily on damage limitation, the course could play into the hands of Primož Roglič or Mattias Skjelmose. The time trial has the potential to completely shake up the general classification once again.

Straight on to the next climbing test

No sooner have the riders recovered from the time trial than the next challenge awaits. The 19th stage of the Vuelta ends with the gruelling final climb to Peñas Blancas near Estepona.

Over much of the day, riders will have already clocked up a considerable number of metres of elevation gain before the final stage begins. There, an 18.7-kilometre climb with an average gradient of 6.5 per cent awaits. Once again, it is the length of the climb that presents the challenge. After the exertions of the time trial, the first signs of fatigue may become apparent here. It is almost impossible to hide moments of weakness on such a long final climb.

The queen stage will decide the Vuelta

Everything suggests that the overall victory will be decided on the penultimate stage. With over 5,000 metres of climbing and four gruelling ascents, this stage is clearly the queen stage of the 2026 Vuelta.

Very early on in the race, the riders will have to tackle the Puerto de El Purche. The climb is 8.2 kilometres long with an average gradient of 8.1 per cent and is tackled twice in quick succession. This combination alone is likely to push many support riders to their limits early on. But that’s not all. Next up is the Puerto del Duque, another Category 1 climb covering 7.4 kilometres at an average gradient of 8.3 per cent. Only then do the riders reach the final showdown.

The final climb to the Collado del Alguacil has everything it takes to be a legendary Vuelta decider: eight kilometres in length, an average gradient of 9.8 per cent, and riders who already have an extremely gruelling day under their belts. There’ll be no more playing hide-and-seek here. Anyone who still has energy left must attack.

Should the overall standings still be very close by then, the Collado del Alguacil will decide who is crowned the winner of the 2026 Vuelta a España just a few hours later. The queen stage is the final major test and probably the last chance to turn the race around decisively.
