Sigrid Haugset of Norway produced one of the most dramatic solo rides in the history of the Tour de France Femmes on Monday, attacking nearly 90 kilometres from the finish to win stage three and seize the overall lead and yellow jersey. The 27-year-old Uno-X Mobility rider launched her lone breakaway on the Côte de la Savine, the third of four climbs on a demanding 156.6km route through the Jura region — a mountainous area straddling the French-Swiss border — between Geneva and the town of Poligny. Her solo effort, the longest in the race's history, gave her a winning margin of 1 minute 24 seconds over Belgium's Lotte Kopecky, a two-time world champion who spent roughly 75 kilometres chasing her down but could not close the gap.

Haugset later admitted she had nearly abandoned the effort. At one point Kopecky closed to within ten seconds, and the Norwegian considered dropping back to let the Belgian catch her. "Second is good," she recalled thinking — before her team car urged her on. Kopecky, for her part, was frank about why she fell short: cramp struck just as the gap seemed closeable. "Ten seconds... and then my legs cramped up," she said. The stage win was only the second professional victory of Haugset's career; her first came just five weeks earlier at the Norwegian national championships.

With the stage triumph, Haugset became the first Norwegian rider to win a stage and wear the yellow jersey at the Tour de France Femmes. "I haven't been thinking about it because I never thought it was possible," she said at the finish. "Standing here, it's unreal." She was so exhausted she could barely raise her arm to celebrate, joking that her boyfriend might be annoyed she failed to salute the crowd.

The main overall favourites — including reigning champion Pauline Ferrand-Prévot and Demi Vollering — finished together in a group nearly three minutes behind Haugset, leaving the Norwegian with a lead of just over two minutes in the general classification. Lorena Wiebes, the Dutch sprinter who had won the opening two stages and held the yellow jersey going into the day, was dropped as soon as the roads began to climb and finished more than 20 minutes down, though she retains the green points jersey.

Haugset now enters Tuesday's fourth stage — a 21km individual time trial between Gevrey-Chambertin and Dijon — as race leader. Whether she can defend that two-minute advantage against riders with stronger time-trialling pedigrees, including Vollering and Ferrand-Prévot, will define whether her extraordinary solo ride proves the foundation of a lasting challenge for overall victory in Nice on August 9.
