Tronchon sensationally wins Vuelta Stage 10 in dramatic photo finish
Bastien Tronchon achieved the biggest victory of his career to date by winning Stage 10 of the 2026 Vuelta a España, raced on September 1 over a 184.7-kilometre route from Alcaraz to Elche de la Sierra. The 24-year-old Frenchman from Groupama-FDJ United survived an exceptionally unpredictable finale, emerged from the group that caught the late attackers in the final metres and narrowly defeated Denmark's Magnus Cort of Uno-X Mobility in a tight photo finish. Third place went to Belgium's Thibau Nys of Lidl-Trek, while Wout van Aert finished fourth. According to the Vuelta's official report, Tronchon claimed victory after passing Yevgeniy Fedorov and Xabier Mikel Azparren only around 50 metres before the finish, after their attack inside the final kilometre had almost completely disrupted the sprinters' teams' preparations. For the Frenchman, it was his first stage victory in one of the three Grand Tours and a result that, in a single stroke, transformed the significance of his professional résumé to that point.
A stage that looked suitable for sprinters turned into a tactical battle
Stage 10 marked the start of the Vuelta's second week after the first rest day, and its profile offered several possible scenarios in advance. The organisers classified the route as a hilly stage: the 184.7 kilometres contained three categorised climbs, while the official report listed a total of 2,991 metres of elevation gain. Because of that configuration, the route was not difficult enough to necessarily separate the general classification favourites, but it was demanding enough to weaken the pure sprinters and encourage attacks from riders who perform best on rolling terrain. That is exactly what happened. There was no prolonged period of complete control in the race, and the final 30 kilometres turned into a succession of attacks, counter-attacks and attempts to form small groups.
According to La Vuelta's official report, 168 riders started from Alcaraz, a town in the Spanish province of Albacete. After several early breakaway attempts, a seven-rider group formed: Enzo Paleni, Michael Gogl, Jasha Sütterlin, Fabian Weiss, Sinuhé Fernández, Iván Cobo and Fredrik Dversnes. Six of them broke away at around kilometre 15, while Dversnes caught them several kilometres later. Their advantage, however, never grew to a level that would seriously threaten the plans of the teams in the main group. Visma-Lease a Bike and Cofidis, whose riders had an interest in bringing the race toward a sprint, kept the gap under control, so the breakaway's largest advantage remained below three minutes.
Three climbs and a constant battle for control
The first categorised obstacle was Puerto del Peralejo, a third-category climb whose summit came at kilometre 47.6. Enzo Paleni was first over the top, while Fabian Weiss was the strongest on the next climb, Puerto de Ayna at kilometre 86.3. The Swiss rider then also crossed the intermediate sprint in Hellín at kilometre 125 in first place. Although the number of kilometres remaining gradually decreased, the escapees had no room to relax because the teams behind them were increasing the pace. Ahead of the final categorised climb, the gap dropped to approximately one minute, opening the door to riders from the peloton who did not want to wait for a bunch sprint.
Puerto de Socovos, also a third-category climb, crested at kilometre 163.2, a little more than 21 kilometres from the finish. It was there that the race became particularly restless. The official report mentions attacks by Eddie Dunbar and Kevin Vermaerke, while Richard Carapaz and Mattias Skjelmose also joined the battle. Enric Mas had to remain alert to prevent anyone who could threaten his position in the general classification from escaping amid the tactical chaos. At the summit of the final climb, the remaining escapees still had around half a minute of advantage, which was enough on the rolling terrain to keep the race completely open.
Dversnes the last to give way, Fedorov and Azparren almost steal the victory
As the road approached Elche de la Sierra, the original breakaway group gradually fell apart. Fredrik Dversnes proved the most persistent among the riders who had spent most of the day ahead of the peloton. After his companions began to drop away, the Norwegian tried to extend his time at the front alone, but new combinations were constantly forming behind him. Sepp Kuss, Iñigo Elosegui and Milan Vader were among the riders who appeared in a late counter-attack, while Decathlon CMA CGM helped close dangerous gaps. According to the race organisers, the final remnants of the breakaway were neutralised around four kilometres from the finish.
Even then, the race did not settle down. Walter Calzoni tried to take advantage of a moment of disorganisation after the breakaway had been caught, but his attack was stopped before the final kilometre. Then Yevgeniy Fedorov, a rider for XDS Astana, attacked under the one-kilometre-to-go banner, and Xabier Mikel Azparren of Pinarello Q36.5 joined him in an effort that looked strong enough to surprise the group behind them. The sprint trains practically no longer existed at that point, because the previous series of attacks had exhausted the domestiques and broken up the usual structure of the finale. Fedorov and Azparren still had a realistic chance of reaching the finish ahead of everyone else on the final straight.
Tronchon launched at the right moment and did not even know whether he had won
It was precisely in that chaos that Tronchon found room to attack. According to the official description of the finale, the Frenchman accelerated powerfully and passed Fedorov and Azparren approximately 50 metres before the finish. Magnus Cort went after him and almost caught him, while Thibau Nys finished immediately behind the leading pair. An independent report by Ireland's RTÉ, based on the PA agency, described the finish as a photo finish and stated that Tronchon held a minimal advantage over Cort. The official classification confirmed Tronchon as the winner, Cort in second and Nys in third, with Van Aert in fourth position.
Tronchon's reaction after the finish showed just how unexpected the outcome was even for him. In an interview published by La Vuelta, he said that when he launched his sprint he was not sure whether some riders were still ahead of him and that, because of this, he did not raise his arms in celebration as he crossed the line. The Frenchman added that the previous days had been difficult for him, but that he felt better on this stage. He particularly highlighted the help of teammate Guillaume Martin-Guyonnet, whom he told in the finale to ride at full strength. His disbelief was understandable: he began the Vuelta without the status of a leading favourite for this type of finish, and the victory came against riders with far greater experience in the finales of major races.
The biggest result of the career of a rider who already knew how to win in Spain
Tronchon was born on March 29, 2002, and the Vuelta's official profile records that even before this success he had several results that demonstrated his potential on rolling terrain and in one-day races. Back in 2022, he won a stage of the Vuelta a Burgos, also in Spain, while in 2025 he won the French classic Tro-Bro Léon. That same year he finished fifth overall at the Tour Down Under and competed in the Tour de France, where he finished inside the top 20 on several stages. In the 2026 season, he moved to Groupama-FDJ United, and before the Vuelta his more notable results included second place on the opening stage of the Vuelta a Andalucía and 21st place at Milano-Sanremo.
The victory in Elche de la Sierra, however, belongs to a different category. A Grand Tour stage victory is one of the most valuable individual results in road cycling, particularly for a rider who has not yet built a reputation as a serial winner in the biggest races. Tronchon reached the finish against rivals such as Cort, a multiple Vuelta stage winner, Nys and Van Aert, and he did not win from a conventionally prepared sprint. His result came from reading a chaotic situation, endurance after almost 3,000 metres of climbing and explosiveness in the final seconds of the race. With that, Groupama-FDJ United secured a stage victory at the 2026 Vuelta.
Van Aert: the final 30 kilometres were exceptionally difficult
Fourth-placed Wout van Aert provided additional insight after the stage into why the finale did not look like a standard sprint. According to his statement published on the Vuelta's official website, the final 30 kilometres were chaotic and very difficult, with the road almost constantly rising slightly uphill. Visma-Lease a Bike had planned to control the stage and set up a sprint for Van Aert, but to carry out that plan it had to use almost the entire team. The Belgian explained that because of this he found himself without enough support for ideal positioning in the final kilometre. In the final 300 metres, according to his own words, he no longer had enough power for the kind of attack he would have needed to win.
That statement describes well the difference between the stage profile on paper and the way it was actually raced. Although a larger group reached the finish, the efforts during the final hour of racing were closer to a demanding one-day classic than to a neatly controlled sprint stage. The fact that Kuss, Carapaz and Skjelmose appeared in the late attacks further increased the tension, because the teams of the general classification contenders had to respond even though the time gaps ultimately did not change. Such an exhausting finale created exactly the kind of unpredictability from which Tronchon benefited most.
Mas retains the red jersey and a 1:18 advantage over Roglič
While the battle for the stage victory was taking place, Enric Mas successfully defended his lead in the general classification. According to the official standings after Stage 10, the Movistar Team leader has a total time of 32 hours, 41 minutes and 44 seconds. Primož Roglič of Red Bull-Bora-Hansgrohe remained second at 1:18, Félix Gall of Decathlon CMA CGM is third at 1:39, Oscar Onley of Netcompany Ineos Cycling Team fourth at 2:20, and Richard Carapaz of EF Education-EasyPost fifth at 3:26. Mattias Skjelmose, Sepp Kuss and Harold Tejada follow, so the battle for the leading positions remains open enough for one difficult mountain stage to significantly change the situation.
Mas said after the finish that his main objective had been to complete the day safely and remain well positioned at all times. In a statement published by La Vuelta, he emphasised that the stage had been much harder and faster than perhaps expected. The Spaniard had strengthened his hold on the red jersey by winning Stage 9, which finished on Alto de Aitani, where he arrived ahead of Oscar Onley. The organisers stated at the time that Mas had increased his general classification advantage over Roglič to 1:18, while Gall remained at 1:39. Stage 10 did not change those key gaps, but it showed that even on a day not designed as a major general classification battle, the leader has to respond to a series of attacks.
The Vuelta enters a phase alternating opportunities for sprinters and favourites
After the unpredictable finish in Elche de la Sierra, the Vuelta programme continues on September 2 with Stage 11 from Cartagena to Lorca. According to the organisers' official data, it is a flatter 153.8-kilometre route, which means the sprinters' teams are again expected to play an important role. However, the experience of Stage 10 shows that the profile alone does not guarantee a controlled outcome. Teams seeking a bunch sprint will have to assess how much their riders and domestiques were drained by the exceptionally fast and aggressive racing through the province of Albacete.
For Tronchon, meanwhile, the situation in the race changes fundamentally. He is no longer merely one of the riders who can look for an opportunity in a breakaway or demanding finish, but a current Grand Tour stage winner whom rivals will watch more seriously in similar situations. His success is also a reminder of how quickly the hierarchy can change in a three-week race: on a day when many expected a duel between established sprinters and classics specialists, the decision came from a rider who, only a few seconds before the finish, was still trying to work out whether he had actually caught all the attackers. In Elche de la Sierra, that uncertainty ended with the most important result of his career, while Mas and the other contenders for overall victory continued toward the next stages with no change at the top of the standings.
