Simon Geschke has 3km of grind to the summit.
Those 18% gradients on the Mur de Peguere - yikes.
The road is so narrow spectators aren't allowed to line it either.
Simon Geschke now has 30 seconds on a big group that still contains Simon Yates, Romain Bardet and Nairo Quintana.
Quick-Step are eating into the advantage of the break, which is down to 3:45 now.
Elia Viviani's work for the day is finally done. A heck of a ride that.
Simon Geschke won a mountainous Tour de France stage in 2015 and wants a second one toady.
The German has kicked off the front.
Elia Viviani is still driving on the front of the peloton up a category one climb. The sprinter is adapting to mountain domestique duties very well.
The pace is spitting Bauke Mollema off the back.
The Quick-Step train have also brought the gap to the break down to four minutes now.
At what number does a gradient become preposterous?

Vincenzo Nibali looked a great shout earlier but the former Tour champion has dropped back from the break to the peloton now.
Could he have something left if it comes back together though?
Deceuninck Quick-Step are making inroads into the gap, bringing it down to 4:20 now with 46km left to race.
Adam Yates will be hoping to regain some time after a horrid day yesterday. How does he see this one going in his BBC Sport stage-by-stage guide?
"By this time of the race the GC is really starting to sort itself out and this can increase the opportunities for a breakaway to succeed, but regardless the battle continues behind. Again, it'll be a battle for the break and a battle for GC. Teams classification and those chasing King of the Mountains points can start to play a part of the stage tactics too."
Rider to watch: "Vincenzo Nibali. The Italian has won each Grand Tour and loves attacking in the mountains. His hopes of winning this year's race may already have gone so he may go chasing a stage win."
Could this be a factor today? A few spots of rain are now falling on the course.
The breakaway are now onto the lower slopes of the Mur de Peguere.

It's a very different look in this year's Tour de France. Ineos, as Sky, have been on the front for years. This year, they are back in the train.

It's 27 degrees where the race currently is...but not at the finish...
Chris Saunders: It’s not a very hot day 700 metres from the end of today’s stage. We’re in the clouds right now!
This is a tricky, technical descent.
Movistar have hit the front of the breakaway group to steer Nairo Quintana through it and potentially increase the gap back to the peloton.
Elia Vivani is still in the Deceuninck Quick-Step train over the Port de Lers. Impressive effort by the Italian sprinter in service of yellow jersey Julian Alaphilippe.
How long can he cling on? The tempo will surely increase over the next and penultimate climb of the day.
Just over 10km of descending left before the break hit the lower slopes of the category one Mur de Peguere.
The peloton are over the top of the Port de Lers and are 5:05 back on the leaders.
Reichenbach and Molard are still in the 21-man break out front.
FDJ playing a blinder so far today.

After a fair while of breaking apart, coming back together, splitting again etc, the breakway now consists of 21 riders out front with a 5:10 advantage over the peloton.
Romain Bardet's bid to win the Tour de France never really got going.
It's been an abject GC campaign from the Frenchman but he may be able to salvage it with an attempt to win the polka dot jersey.
The AG2R La Mondiale leader zips off the front of the break and easily claims the 10 king of the mountains points for the first rider to the top of the Port de Lers.
Nairo Quintana has just moved above Geraint Thomas into virtual second place.
