Defending champion Jonas Vingegaard kept the overall lead of the 2023 Tour de France on Sunday, crossing the finish line in the second of four Alpine tests wheel to wheel with Tadej Pogacar.

Dutch climber Wout Poels won the 15th stage, raced in the shadow of Mont Blanc, and dedicated his win to the memory of recently deceased teammate, Gino Maeder.

In the long-term duel for the overall title between the two top riders, Vingegaard remains 10 seconds ahead of Pogacar.

In the Alps, Vingegaard appears to have stemmed the tide. After three days of Pogacar clawing back time, the last two stages been even, with Vingegaard gaining one second over the weekend.

The 179-kilometer run from Les Gets to Saint Gervais Mont Blanc again was dominated by both their duel, but also by a series of falls.

Pogacar twice attempted characteristic blistering late attacks. Vingegaard caught up both times and then sped past approaching the line, only to slow and look his Slovenian rival in the eye as they crossed together.

Monday is a rest day ahead of a potentially decisive individual time-trial on Tuesday, which is followed by another Alpine stage Wednesday.

Pogacar said he was looking forward to the next two stages.

"Tuesday's time trial will provide a shakeup, and Wednesday's stage has some of the hardest climbs in cycling," said the 2020 and 2021 Tour winner. "Tuesday and Wednesday will decide the winner of the Tour. I have tested the course for the time trial, and I like it."

His Danish rival also likes the look of Tuesday's test and suggested he was saving his powder.

"I felt good today, and I don't know if I was thinking about attacking, but it didn't make sense," Vingegaard said. "I like short, hard time trials like (Tuesday's), there will be lots of change of pace, and I like that."

Young Gun Consolidates Third Place

Carlos Rodriguez is more than five minutes behind in third, but the 22-year-old Spaniard, on his first Tour, tightened his grip on a podium place, as Australian Jai Hindley dropped to fifth. Briton Adam Yates rose to fourth.

Sunday's winding route through wild Alpine meadows and valleys featured five mountains, but the expected fireworks were doused by an early mass fall.

Rowdy roadside fans have caused continual havoc on this Tour. On Sunday, a clumsy spectator brought down half the peloton after stepping out into the road about 60 kilometers in.

An escape group built an eight-minute advantage the chief pretenders showed no appetite to close in sizzling summer temperatures.

Italian Lidl-Trek rider Giulio Ciccone was part of the day's big break and took over the polka dot jersey for climbing points.

"For a climber to pull on this jersey at the Tour de France, you have to know how much that means," said Ciccone, who took the yellow jersey briefly early in the 2019 Tour de France.

Raced within view of massive Mont Blanc, with its snow-capped peak, French hopes again were battered a day after Romain Bardet crashed out, with David Gaudu dropped on the last climb.

Riders again tangled with motorbikes. On Saturday, one had blocked a Pogacar attack. On Sunday, Krists Neilands was knocked over by a motorbike delivering water.

Colombian EF rider Rigoberto Uran ran off a mountain road only to get back up and carry on, and there were incidents of riders taking wrong turns.

Bryan Coquard, the French sprinter, broke his handlebars but, with the team car unable to reach him with a replacement, still negotiated a mountain descent.
