Mads Pedersen finished off a brutal breakaway day in Foix, while Torstein Træen turned the peloton's surrender into the first yellow jersey of his life.

Stage 4 looked like a hilly transition on paper and turned into a full redraw of the race. Mads Pedersen won the sprint from a reduced break in Foix after Lidl-Trek spent all afternoon stacking the move in their favor, and Torstein Træen stepped onto the top of the Tour with the yellow jersey after the peloton rolled in 12:59 down.

The official stage report called it "Northern Power" in Foix, which fits the two biggest outcomes. Pedersen collected his third career Tour stage win and his first green jersey in the race, while Træen became the third Norwegian ever to lead the Tour de France. The split between the break and the favorites was not an accident; UAE Team Emirates-XRG stopped defending after the move swelled to 34 riders, and once the gap drifted beyond seven minutes on the Col de Coudons, the general classification was up for auction.

Lidl-Trek raced the day like they had written the script the night before. Pedersen made the move, Quinn Simmons forced the pressure from the front, and Mathias Vacek kept appearing exactly where the race needed him. By the time the break hit the final categorized climb at Montsegur, the front had been shaved down to the riders who could climb and still finish fast. Pablo Castrillo and Raul Garcia Pierna attacked, Kevin Vauquelin tried to surprise the group late, but Pedersen survived the hard parts with both Simmons and Vacek still around him. From there the sprint was almost unfair.

Lidl-Trek did not just win the stage. They dictated which version of the stage was allowed to exist.

Yellow changes hands by design and by drift

Træen was the best-placed rider in the break at +5:06 on GC when the day started. That gave Uno-X Mobility a simple brief: stay fed, stay cool, and stay away. The Guardian's stage report tracked the heat at around 40C, and the official race recap showed how much that mattered. Emergency drinks and constant cooling became part of the race story, and the bunch never seriously tried to close the gap once the stage win and the jersey began pointing in different directions.

After Foix, Træen leads Sean Quinn by 28 seconds, Vacek by 3:50, and both Tadej Pogačar and Jonas Vingegaard by 7:53. That is not enough to make Træen the favorite for the Tour, but it is enough to change the race's rhythm before the first true Pyrenean examination. Pogačar lost yellow on the first day he wore it for the third straight year, and Visma-Lease a Bike suddenly moved from a head-to-head duel into a race with a real outsider sitting between the giants and the jersey.

Heat, attrition, and a GC truce that cost minutes

Foix was not a day of crashes or scandal. It was a day of consent. UAE let the break keep breathing. Visma let the jersey go with it. EF Education-EasyPost chased for Sean Quinn but never had enough to bring back a move this deep. The race effectively split into two different contests: a stage for the attackers and a future mountain fight for the favorites.

That left secondary prizes exposed too. Pedersen's intermediate and finish points moved him into green. Alex Baudin held onto the mountains jersey. Vacek's ride was strong enough to earn white as well as the final lead-out labor. By sunset, Lidl-Trek had taken the stage, the points jersey, the youth jersey, and a one-two on the line. Uno-X took the only jersey that mattered more.

What changed before Pau

Stage 5 into Pau was always supposed to be simpler: 158.3 kilometers, flatter roads, and a first clear invitation for the pure sprinters. But Stage 4 made it more than a holding pattern. Træen had to defend yellow for the first time. Pedersen had green to protect after a draining day in the break. And every major contender could see the Tourmalet looming on the following stage, which made the choice to spend or save energy in Pau more consequential than a normal sprint prelude.

Foix did not prove Træen can win the Tour. It proved he can force everyone else to race on a less comfortable script.
