Sky team-mates Bradley Wiggins and Chris Froome appeared uncomfortable with each other today as they rode to certain Tour de France victory up the Peyragudes climb.

An accelaration by Wiggins dropped their main rival rival Vincenzo Nibali, but once they had done that they seemed unsure of what to do next.

Alejandro Valverde (Movistar) was up the road having attacked the escape group on the Col de Peyresourde and looked ready to clinch the stage on the short ramp up Peyragudes. In the final kilometres Wiggins and Froome looked like they could catch him, but instead they looked at each other, exchanged words, and rode with uncertainty on the Peyragudes.

Froome protected Wiggins’ lead and rode at the front, but he could have gone faster still. On a few occasions he had to slow down. He looked back at Wiggins several times as if to be searching for the OK to chase Valverde and go for the stage win. Had he succeeded it would have been his second stage win and gained him extra time on Nibali who sits third overall, one place behind him.

Eventually they crossed the line together, 19 second behind Valverde. Froome took second and Wiggins third and they both put another 18 seconds in to Nibali. Froome now has a 36 second buffer over Nibali with one key stage left to race; Saturday’s long time trial. Journalists circled them at the finish and asked, “What happened?”

“We were talking about Nibali. We knew he was on his limit. Chris said he wanted to go for the stage and I said yes. We weren’t too sure of the time gaps,” Wiggins explained.

“The moment we crossed the Peyresourde, I allowed myself to drift and that was the first time I thought maybe I’ve won the Tour today. All the way up that last climb my concentration had gone, everything about performance had gone. Chris was egging me on to take more time and I was in another world, really.”

Froome rode to Sky’s team camper parked off to the side of the finish line at 1,605 metres above sea level. He put on a warm jacket and reflected on the stage.

“It was the plan to do the job to retain the yellow jersey, to protect it,” he said to French television. “Everybody makes sacrifices, [Mark] Cavendish makes sacrifices everyday, everybody in the team makes sacrifices for the yellow jersey. It’s cycling, it’s our sport.”

Wiggins spoke about Froome’s support in this Tour de France later in the press conference.

“He’s been absolutely solid for me the whole Tour,” Wiggins explained. “He’s just one less thing to worry about. If he was in an opposing team then you’d constantly have that battle all the time. Yeah, so I think… It don’t take a rocket scientist to work it out, you’d rather have him in your camp than in someone else’s. He’s an incredible climber.”

Froome re-signed for team Sky for another three years after placing second in last year’s Vuelta a España. He appeared to be the best climber in this Tour and some say that he could have won the race.

“Maybe [the chance to win] it’s not going to happen again. That would be bad,” Froome continued. “But I’m 27 and I hope I’ll be luckier later.”
