ELCHE DE LA SIERRA, Spain — Bastien Tronchon produced one of the biggest surprises of the 2026 Vuelta a España on Tuesday, powering to a dramatic Stage 10 victory after a chaotic final kilometre turned an expected sprint into a frantic fight for the line.
The 24-year-old Frenchman of Groupama-FDJ United edged Magnus Cort of Uno-X Mobility and Thibau Nys of Lidl-Trek in a tight finish at Elche de la Sierra, securing his first Grand Tour stage victory and the third professional win of his career. Wout van Aert finished fourth.
The stage covered 184.7 kilometres from Alcaraz to Elche de la Sierra over a hilly route in southern Spain. Official race information classified the stage as hilly, with more than 2,700 metres of climbing, setting up a finale that was never likely to resemble a straightforward flat sprint.
A Sprint That Nearly Never Happened
For much of the closing phase, Team Visma | Lease a Bike appeared to be positioning itself for another victory, with Wout van Aert among the leading contenders.
But the team’s control began to unravel in the final kilometres.
After a series of attacks had shaken up the peloton, Astana’s Yevgeniy Fedorov and Xabier Mikel Azparren of Q36.5 launched a late move with roughly a kilometre remaining.
For a moment, the two attackers appeared capable of stealing the stage.
Then everything changed.
The peloton finally closed them down just before the finish, but the chase had destroyed the organised sprint trains. Instead of a perfectly controlled lead-out, riders were forced to improvise in the final metres.
Tronchon reacted fastest.
The Frenchman launched his sprint at precisely the moment the race was at its most disorganised and held off the chasing riders to take a remarkable victory.
Even Tronchon wasn’t immediately convinced that he had won.
“I launched my sprint and finished on the line — I wasn’t sure if there were some guys in front,” he said after the stage. He also admitted that his preparation for the season had not gone as planned and that he had not expected to produce such a result.
Visma’s Control Turns Into Chaos
The result was particularly surprising because Visma had spent much of the day helping control the race with an eye toward a sprint finish.
According to reports from the cycling press, Matthew Brennan was heavily involved in the late chase, helping bring attacks back while Van Aert waited for the expected sprint opportunity.
But by the time the final attacks arrived, the team had lost the kind of organised lead-out that could have placed Van Aert in the perfect position.
That opened the door for riders who had been waiting for the chaos.
Tronchon took it.
Velo’s race report described the finale as a situation in which Visma lost its grip on the race after the late attacks disrupted its sprint strategy.
The final result was a podium few would have predicted before the finish:
1. Bastien Tronchon — Groupama-FDJ United
2. Magnus Cort — Uno-X Mobility
3. Thibau Nys — Lidl-Trek
4. Wout van Aert — Visma | Lease a Bike
5. Alessandro Romele — XDS Astana
The top finishers were recorded on the same time, with Tronchon completing the stage in 4 hours, 7 minutes and 41 seconds.
Tronchon: “It’s Crazy”
The victory carried extra significance for Tronchon because it represented the biggest result of his career.
Rather than entering the stage as one of the obvious favourites, he capitalised on a race that became increasingly unpredictable as the finish approached.
After crossing the line, Tronchon could barely believe what had happened.
His own reaction reflected just how unexpected the victory was: he said he hadn’t been certain that all of the attackers had been caught and admitted that he had not even celebrated immediately.
That hesitation made the finish even more remarkable. In a race where established sprint names such as Van Aert, Cort and Nys were expected to dominate the final acceleration, Tronchon timed his move perfectly.
Enric Mas Keeps the Red Jersey
While the stage victory changed hands dramatically, the overall classification remained stable.
Enric Mas of Movistar safely finished in the main group and retained the red leader’s jersey.
Mas entered Stage 11 with a 1:18 advantage over Primož Roglič, while Felix Gall sat third at 1:39 and Oscar Onley fourth at 2:20.
The general classification therefore remains tightly poised heading deeper into the second week of the race.
Mas’s position is particularly significant after his Stage 9 victory on Alto de Aitana, which strengthened his grip on the overall lead before Tuesday’s stage.
What Comes Next?
The Vuelta now moves into Stage 11 on Wednesday, September 2, with a Cartagena-to-Lorca route.
The race heads toward another phase where the battle for the red jersey could intensify, while the sprinters and puncheurs will have to decide whether to wait for another opportunity or try to attack before the mountains return.
For Tronchon, however, Stage 10 will remain the defining moment of his Vuelta.
He arrived at the finish without knowing whether his effort had been enough.
A few seconds later, he discovered that the chaos had delivered him the biggest victory of his career.
