The big loser of the day was Colombia's Nairo Quintana, twice a runner-up to Froome, who was dropped on the Peyra Taillade climb and lost nearly four minutes by the finish to the other contenders, dropping from eighth to 11th at 6:16. Chris Froome (Sky) 64:40:21 2.
Truly, this outcome was only in doubt for about 20 minutes, the amount of time it took Federer to grab his first lead.
It's unlikely the sprint specialists in the field will be figuring to lead anywhere other than the stage's final phases, with the combination of steep climbs in quantity playing more to the strengths of the mountain climbers. He finished hot on the heels of Matthews.
Froome said: "Well there's never a boring moment on this Tour".
Landa gained 1:46 on Aru and Froome to move up the standings.
As for the girls, he said: "They enjoy to watch a little bit".
"He was on his own, isolated", Fofonov said.
"We've always battled, we've been there and you don't lose quality overnight", said the Movistar team leader. Then the finish was explosive, with sprinters climbing very fast. Froome sits just 18 seconds clear at the top of the general classification, ahead of Aru. I've worked for it so hard. "After the last ascent, I noticed how exhausted everyone was and how they kept looking at each other, so I said to give it a try". "But that he was going to be 29 seconds behind? No".
Ireland's Dan Martin pedaled away on a flat section after the descent to gain 12 seconds on Froome and the other favorites.
"The GC (overall) time, I've ignored it, it's happened".
Froome was impressed. "He has ridden a very good race so far". Conversely, all three points won by Federer in that game were thanks to forehand miscues by Cilic. He had a lead of 1:47 after Stage 14 in 2016, of 3:10 in 2015 and 2:28 in 2013.
The first occurred on a key climb of last Sunday's ninth stage to Chambery. He had no challengers at the finish as he rode across the line alone to complete the victory.
"I never set objectives, I never say my ambitions".
"I'd like to think when we were controlling the race it was a bit calmer".
Dutchman Bauke Mollema won the stage after a fearless solo break on a lumpy 190km stage from Laissac-Severac l'Eglise to Le Puy-en-Velay.
"He won't do it again", Rowe said.
