Extreme heat shortened the Vuelta stage by almost 80 kilometres, Van Aert celebrated again in Córdoba
Extreme heat marked the conclusion of the second week of the Vuelta a España 2026. The fifteenth stage, which on 6 September was supposed to run from Palma del Río to Córdoba over 189.7 kilometres, was shortened to 110.2 kilometres after the high-temperature protocol was activated. The organisers therefore removed 79.5 kilometres from the route, moved the start of the race to a later time and changed the central part of the route to reduce the riders' exposure to the harshest conditions. Despite these measures, the road temperature during the stage remained very high, and some riders after the finish spoke of readings above 40 °C. In such circumstances, Wout van Aert of Visma-Lease a Bike handled the conditions best, winning the sprint from the final group of five riders and claiming his second stage victory at this year's Vuelta.
The Belgian beat Italy's Alessandro Romele of XDS Astana and his compatriot Thibau Nys of Lidl-Trek in Córdoba. Enric Mas of Movistar finished safely in the main group with the other favourites for overall victory and retained the red jersey. After 15 stages, Mas leads Felix Gall of Decathlon CMA CGM by 2:06, while Primož Roglič of Red Bull-BORA-hansgrohe trails by 2:10. Vuelta organisers state that the peloton reached the finish 2:44 after Van Aert, with no changes among the leading contenders in the general classification. The race then entered its second and final rest day, on 7 September, before the decisive final week.
Organisers changed the route after a meeting with riders and teams
The decision to shorten the stage was made on 5 September, the day before the start, following forecasts predicting temperatures around and above 40 °C in Andalusia. According to the Vuelta's official statement, the organisers activated the extreme-temperature protocol after a meeting attended by representatives of the commissaires' panel, teams, riders and race management. The aim, the organiser stated, was to protect the competitors' health and allow the stage to be held in more acceptable conditions. The neutralised start was moved to 14:50, with the official start of racing at 15:00 local time. The route change was applied from kilometre 52, where the peloton was directed along the CO-3402 road towards Santa María de Trassierra instead of towards Villaviciosa de Córdoba.
The original stage had been designed as a considerably longer and more demanding medium-mountain day, but after the modification, 110.2 kilometres remained with two categorised climbs. The official Vuelta profile lists Puerto de la Forestal, a third-category climb 6.7 kilometres long with an average gradient of 4.1 percent, and Puerto Artafi, also third category, 5.9 kilometres long at an average of 5.5 percent. After the second climb came the passage through Santa María de Trassierra, the intermediate sprint at kilometre 78.9, rolling terrain and the descent towards Córdoba, while the final ten or so kilometres were predominantly flat. The stage therefore lost a large part of its original distance, but retained enough climbing and technically demanding terrain for aggressive racing.
Official race data during the afternoon recorded a temperature of almost 37 °C at the head of the race, while reports from the finish spoke of even higher readings registered by riders on their own devices. Matthew Brennan, Van Aert's teammate, said after the stage that his meter had shown an average temperature of approximately 41 °C during the ride and a reading of 44 °C on one of the earlier climbs. Brennan publicly expressed concern about the conditions and the risk of heat-related problems, despite the stage having already been shortened. Those figures are not identical to official meteorological measurements of air temperature, but they show how much greater the heat load on the asphalt and bicycle may have been than the values recorded at standard weather stations.
UCI protocol provides for changes to start times, additional cooling and route modifications
Shortening the stage was not an improvised decision without a regulatory framework. The Union Cycliste Internationale, UCI, introduced a specific high-temperature protocol as an addition to the broader extreme weather protocol, which has been applied in professional road cycling for years. When presenting the measures, the UCI stated that the protocol should help organisers, commissaires, teams and riders' representatives assess the risk created by the combination of temperature, relative humidity and the specific physical strain during a race. The system provides for several risk levels and a meeting of relevant stakeholders when conditions reach a level at which additional measures are required.
Among the possible measures listed by the UCI are moving start areas into the shade or shaded zones, providing larger quantities of cold drinks and crushed ice, increasing the number of supply motorcycles, shifting the start time, and neutralising or modifying sections of the route. The final decision on which measures will be implemented depends on local conditions and the assessment of the working group at the race itself. In the case of stage 15 of the Vuelta, the two most visible interventions were applied: a later start and a major shortening of the route. The organiser retained the start in Palma del Río and the finish in Córdoba, but removed the more northerly part of the planned loop and reduced the total amount of time the peloton was expected to spend on the road.
The UCI warns in its rules that competition in high temperatures can reduce physical performance, but also increase the danger of serious heat-related disorders, including exertional heat stroke. The risk does not depend solely on air temperature, but also on exercise intensity, acclimatisation, humidity, clothing and other factors. Road cycling is particularly sensitive because competitors produce large amounts of metabolic heat for hours, often on open roads without shade. That is precisely why the protocol does not prescribe a single universal temperature at which a race must be stopped, but instead provides for an assessment of the overall conditions and a range of possible responses.
The short stage turned into an attack from the opening kilometres
The reduced distance also changed the sporting dynamics of the stage. Instead of a long day in which a breakaway would gradually form and gain space, the race was very fast and full of attacks from the start. According to the Vuelta's official summary, 150 riders started from Palma del Río, and after approximately 15 kilometres a group of 11 cyclists broke clear. It included Frederik Wandahl, Ivo Oliveira, Xabier Mikel Azparren, Enzo Paleni, Ethan Hayter, Andreas Leknessund, Rudy Porter, Alastair Mackellar, Fabian Weiss, Reuben Thompson and Gijs Leemreize. Their maximum advantage was only 1:17, showing that the peloton was not prepared to allow a traditional breakaway to decide the winner early.
Visma-Lease a Bike and Cofidis took on a large part of the work in the main group and kept the gap under control. Georg Steinhauser attacked on the Puerto de la Forestal climb and joined the leaders, briefly increasing the front group to 12 riders. However, the gap began to fall again as the race approached Puerto Artafi. On the second categorised climb, the pace increased further and the original group began to break apart. Leknessund managed to leave his rivals behind, while Ramses Debruyne closed in on him on the descent.
The decisive moment came around the intermediate sprint in Santa María de Trassierra. Romele and Van Aert drew closer to the two leaders, and Nys recognised the danger and also bridged across. That created the final group of five consisting of Leknessund, Debruyne, Romele, Van Aert and Nys. The peloton then slowed enough for the five to build an advantage that could no longer be closed, while attempts by other riders from behind proved unsuccessful. According to the Vuelta's official report, the closest chasers were unable to get within approximately 45 seconds in the final part of the stage.
Van Aert controlled the attacks and saved the strongest sprint
The finale in Córdoba was tactical, but Van Aert did not allow his opponents to surprise him. Nys tried an attack around three kilometres from the finish, and then Leknessund also looked for an opportunity to escape alone. The Belgian in the green points-classification jersey responded to the key moves and tried to keep the group together for the final sprint. Nys went early, with approximately 300 metres remaining, but Van Aert gradually caught him and passed him in the final metres. Romele finished second, Nys third, while Debruyne and Leknessund completed the leading group.
After the victory, Van Aert explained that Visma had controlled the race throughout the day, but that around the intermediate sprint he judged that his rivals would not expect his attack. According to his comments in the Vuelta's official interview, Matthew Brennan's presence in the peloton gave the team additional security: if Van Aert's move failed, Visma still had a strong option for a possible sprint from a larger group. The Belgian also emphasised that the final group of five was difficult to control because Nys, Debruyne and Romele had enough strength to attack, while Leknessund tried to exploit the situation tactically. The plan in the final kilometres was therefore to keep the group together for as long as possible and rely on his finishing speed.
The victory carried additional symbolism for Van Aert because he had also won in Córdoba in 2024. On that occasion, he won stage seven of the Vuelta in a reduced sprint from a larger group of riders, while this time he triumphed after aggressive racing and a finish from a small group. Official Vuelta statistics state that this was his fifth career stage victory in the Spanish Grand Tour and his 16th stage victory overall across the three biggest three-week races: in addition to five at the Vuelta, he has ten at the Tour de France and one at the Giro d'Italia. At the 2026 Vuelta, this was his second victory, following his success in stage 13, continuing the exceptionally successful run of the Visma-Lease a Bike team.
Mas safely retained the red jersey before the final week
While the battle for the stage victory was taking place at the front, the general-classification leaders did not engage in any serious battles among themselves. Movistar maintained control over the group of favourites, and Enric Mas crossed the finish together with his main rivals. After stage 15, the Spaniard has an overall time of 52:05:56 and a lead of 2:06 over Felix Gall. Primož Roglič is third at 2:10, Richard Carapaz fourth at 4:24, and Oscar Onley fifth at 5:44. That leaves only four seconds between Gall and Roglič as one of the most interesting gaps immediately behind race leader Mas.
The shortening of the stage probably reduced the scope for major changes in the general classification, because a substantial part of the originally planned distance and climbing was removed. Nevertheless, the decision was made primarily because of the health risk, not because of the sporting character of the stage. Mas entered the rest day with the same advantage with which he had begun the day, while Van Aert and his team extracted the maximum result from the altered route. After 15 stages, Visma had five stage victories at this year's Vuelta: Brennan had achieved three and Van Aert two.
The battle for overall victory is only now entering its crucial phase. According to the official route, stage 16 takes place on 8 September from Cortegana to La Rábida in Palos de la Frontera over 181.1 kilometres of rolling terrain. The following day brings a 185-kilometre flat stage from Dos Hermanas to Seville, while on 10 September a 32.1-kilometre individual time trial is scheduled between El Puerto de Santa María and Jerez de la Frontera. The final major tests for the favourites come in stages 19 and 20, including finishes at Peñas Blancas and Collado del Alguacil, before the final stage in Granada on 13 September.
Heat remains one of the key issues in professional cycling
The events in Andalusia once again showed how much weather conditions can change the character of a Grand Tour stage in only a few hours. In this case, the organisers managed to retain the start and finish cities, the television and competitive framework, and most of the key sporting elements, but with a route almost 42 percent shorter than originally planned. The race nevertheless remained extremely demanding, as shown by the high average speed, continuous attacks and the riders' comments after the finish. It is particularly significant that questions about heat stress continued even after the protocol was activated, because shortening a stage by itself does not remove the danger if the remaining portion is ridden in extremely high temperatures.
When introducing the high-temperature protocol, the UCI emphasised that professional road races are increasingly being held in difficult climatic conditions and that a system is needed that enables a faster and more structured response. Stage 15 of the 2026 Vuelta became a concrete example of such an approach: the decision was made in advance, after consultations, the route was substantially shortened, and the start was delayed. At the same time, reactions from the peloton show that the debate about the limits of acceptable risk is likely to remain open, particularly in summer races in southern Europe.
For Van Aert, however, the sporting outcome was almost ideal. In a city where he already had winning experience, he combined endurance, attacking instinct and sprinting ability, taking advantage of a situation in which many pure sprint specialists were out of contention for victory. Mas, on the other hand, achieved what mattered most for him and Movistar: he avoided problems, retained his advantage and reached the rest day in the red jersey. After an extremely hot Sunday in Córdoba, attention now turns to the final six stages and the question of whether Mas can defend a lead of more than two minutes through the time trial and the final mountain battles.
