Demare wins 18th stage, Thomas looks to cement Tour lead in final mountain leg

Arnaud Demare was rewarded Thursday for hauling his muscular frame over the Alps and through the Pyrenees.

Geraint Thomas, meanwhile, is preparing to cement his hold on the yellow jersey in Friday's final mountain test of the Tour de France.

After many of his competitors were unable to get through the mountains, Demare took advantage by dominating a mass sprint in Stage 18.

It marked the first victory by a French team, Groupama-FDJ, in this year's race.

Sprinters Fernando Gaviria of Colombia and Dylan Groenewegen — who had each won two stages in this Tour — called it quits during Stage 12 to Alpe d'Huez. That came a day after Mark Cavendish and Marcel Kittel, who have a combined 44 Tour stage wins between them, failed to make the time cut on another mountain leg.

Demare said he was motivated by an accusation on social media from Andre Greipel, a top German sprinter, who alleged that Demare held on to his team car on the way up the grueling Col du Portet in Stage 17.

Demare finished Wednesday's stage second to last but managed to avoid the time cut as thousands of French spectators cheered him on.

Greipel, who also quit in Stage 12, later apologized on Twitter, saying he had relied on "incorrect" information.

"It hurt me enormously," Demare said. "It's a shame that people cast doubts over my performance and my hard work. ... I thought a lot about (Greipel) today. It's not in my mindset or my philosophy to (cheat). I worked hard in the mountains before the Tour and, as a result, I made it through mountain stages when most of the sprinters did not."

Demare, who failed to make the cut on a climb in the Alps last will try to take every opportunity they can," Thomas said. "But we've been riding real well the whole race, so hopefully we can keep that going for one more day."

After Froome cracked on the Col du Portet, all of Sky's strategy is aimed at getting Thomas to Paris in yellow — meaning Froome may have to help.

"Hopefully we won't have to use Froomey. Hopefully we'll have strength in numbers and he'll be able to just follow as well," Thomas said.

"But obviously having Froomey at my disposal, so to speak, is just phenomenal."

Perhaps a bigger worry for Thomas and Froome concerns the unruly fans who have consistently affected this Tour by spitting at riders — or even reaching out to grab them.

One fan who reached over the barriers nearly took Thomas down on Wednesday

"I thought it was maybe an accident, just maybe an overly exuberant fan," Thomas said. "But when I got back to the hotel and was showed the pictures it was obviously something else. It's not nice. It's not what you want."

On a warm day in southern France, Stage 18 took riders through the vineyards of Madiran to the city of Pau, the birthplace of 16th-century King Henri IV. It was the 70th time that the Tour passed through Pau, which first hosted the race in 1930.

Five riders — Guillaume Van Keirsbulck (Wanty-Groupe Gobert), Mathew Hayman (Mitchelton-Scott), Luke Durbridge (Mitchelton-Scott), Niki Terpstra (Quick-Step Floors) and Thomas Boudat (Direct Energie) — were involved in an early breakaway. The sprinters' teams never let them get much more than two minutes ahead, and they were caught with 16.5 kilometers to go.

Otherwise, it was a very calm stage except for a minor crash involving Stage 17 winner Nairo Quintana and British rider Adam Yates midway through the route. Both riders got back on their bikes and continued without apparent problems.
