The Polish rider launched a devastating long-range attack on the race’s most iconic climb, taking her first Tour stage victory and overturning the general classification with two days remaining.

Katarzyna Niewiadoma-Phinney produced one of the defining performances of the 2026 Tour de France Femmes on Friday, attacking almost 10 kilometres from the summit of Mont Ventoux and riding alone to a commanding stage victory that propelled her into the overall race lead.

The 31-year-old Polish rider crossed the summit finish 1 minute 16 seconds ahead of Demi Vollering, having broken clear of the principal contenders on the exposed upper slopes of the legendary Provençal mountain.

It was Niewiadoma-Phinney’s first stage victory at the Tour de France Femmes and a dramatic statement from the 2024 overall champion, who began the day third in the general classification and 1 minute 17 seconds behind race leader Marlen Reusser.

By the time she reached the summit, that deficit had been erased.

Niewiadoma-Phinney now leads Vollering by 15 seconds overall, while former race leader Reusser has fallen to fourth, 39 seconds behind the new yellow jersey. Elisa Longo Borghini moved into third after a strong finish on Ventoux.

The transformation of the race came during the decisive final ascent of Mont Ventoux, one of cycling’s most celebrated and feared climbs.

Friday’s 146.8-kilometre stage began in La Voulte-sur-Rhône and culminated with the Tour de France Femmes climbing Ventoux for the first time in the modern race’s history.

Before the stage, much of the attention had focused on Reusser and Vollering.

Reusser entered the day wearing yellow after a powerful performance earlier in the race, while Vollering sat just 12 seconds behind her. Niewiadoma-Phinney appeared to face a significantly more difficult task, beginning the stage more than a minute down.

Instead, she turned the expected duel between Reusser and Vollering into a solo exhibition.

With approximately 9.7 kilometres remaining, Niewiadoma-Phinney accelerated decisively and immediately opened a gap. Neither Vollering nor Reusser responded quickly enough.

The Polish rider continued to increase her advantage despite the exposed terrain and headwind near the summit.

Behind her, tactical hesitation between Vollering and Reusser helped the gap grow. Reusser later acknowledged that the pair had concentrated too heavily on marking one another while Niewiadoma-Phinney disappeared up the road.

By the final kilometres, the question was no longer whether Niewiadoma-Phinney would win the stage, but whether she could gain enough time to take yellow.

She did.

Vollering eventually broke clear of Reusser and began limiting the damage, but Niewiadoma-Phinney had already established a decisive advantage.

She reached the summit alone in 4 hours, 22 minutes and 53 seconds, completing a performance that fundamentally reshaped the battle for the Tour.

The victory carried considerable emotional significance.

Niewiadoma-Phinney revealed after the finish that she had trained extensively on Mont Ventoux with her husband, former professional cyclist Taylor Phinney. Seeing members of her family on the climb added to the emotion of a victory she had pursued throughout her Tour career.

The result also marked a striking comeback in the general classification.

Only two days earlier, Niewiadoma-Phinney had acknowledged that overturning her deficit would require an exceptional performance. Her aggressive riding on Ventoux provided exactly that.

For Vollering, the stage produced mixed consequences.

The Dutch rider could not follow the winning attack, but her late acceleration allowed her to move into second place overall and keep the yellow jersey within reach.

At 15 seconds, the gap is small enough to ensure that the Tour remains unresolved.

Reusser endured a considerably more damaging afternoon.

The Swiss rider had started the stage as the overall leader and had appeared to be one of the strongest riders in the race after winning the individual time trial earlier in the week.

But Ventoux exposed the limits of her defence.

Unable to match Niewiadoma-Phinney’s acceleration and later losing ground to Vollering and Longo Borghini, she surrendered the yellow jersey and fell off the podium.

The mountain also dealt severe blows to several other contenders.

Defending champion Pauline Ferrand-Prévot was among the riders unable to remain with the leading group as the gradients intensified, while stage-six winner Kim Le Court-Pienaar also lost significant time.

The severity of the damage demonstrated why Mont Ventoux had been viewed as the defining feature of the 2026 route.

The climb rises dramatically above Provence and has long occupied an almost mythical place in the men’s Tour de France. Its barren upper slopes, shifting winds and prolonged gradients have produced some of the sport’s most famous moments.

Its inclusion in the Tour de France Femmes therefore carried symbolic significance as well as sporting importance.

Race director Marion Rousse had previously emphasized the importance of incorporating legendary Tour climbs as the women’s race continues to grow in stature.

Niewiadoma-Phinney’s performance ensured that the first modern women’s Tour ascent of Ventoux immediately produced a memorable chapter.

Yet the race is not finished.

Two stages remain before the Tour concludes in Nice on Sunday.

Saturday’s eighth stage covers 171.9 kilometres from Sisteron to Nice. Although less decisive than Ventoux for the overall classification, the route still contains substantial climbing and opportunities for attacks.

The final stage on Sunday consists of a 99.2-kilometre circuit around Nice, giving Vollering, Longo Borghini, Reusser and their teams one final opportunity to challenge Niewiadoma-Phinney’s advantage.

With only 15 seconds separating first and second place, tactical decisions and bonus seconds could prove decisive.

Niewiadoma-Phinney therefore faces a very different challenge from the one she mastered on Ventoux.

On Friday, she could attack.

For the final two days, she must defend.

Her rivals are unlikely to allow her to control the race comfortably, particularly Vollering, who remains close enough to overturn the classification with one well-timed move.

The situation also carries historical significance.

Niewiadoma-Phinney won the Tour de France Femmes in 2024. A second overall victory would reinforce her position among the defining stage racers of her generation and could make her the first rider to claim another title after returning to the top of the race following a previous victory.

Whatever happens in Nice, however, the 2026 race already has its defining image.

On the slopes of Mont Ventoux, with the yellow jersey apparently beyond reach at the start of the day, Niewiadoma-Phinney chose aggression over caution.

She attacked nearly 10 kilometres from the summit, rode away from the strongest climbers in the race and transformed a 77-second deficit into a 15-second lead.

The mountain that was expected to decide the Tour may have done exactly that.

Now Niewiadoma-Phinney must ensure that what she won on Ventoux survives all the way to Nice.
