5km to go
The wily French veteran Sylvain Chavanel tries to go.
He's matched by the young French debutant Elie Gesbert.
Movistar's Daniele Bennati perhaps the dark horse in this front group - the Italian used to be a fast sprinter, still has a good kick and is a very crafty racer.
Jens Keukeleire has been awarded the most aggressive rider price of the day.
I'd wager the Belgian would rather the stage win, either for himself or team-mate Michael Albasini.
The front nine now have a gap of 37 seconds on the second group on the road.
Surely it's one from nine now.
8km to go
The youngest man in the race, Elie Gesbert, has a dig and briefly distances six of the front nine.
Thomas de Gendt covers and closes the gap.
The front group can't afford to start playing around - any attack and counter-attack right now might bring back the chasing 11.
So they still have to work together and work hard to increase the gap. No long-distance attacks yet.
Increasingly looks like today's winner will be one of Jan Bakelants, Daniele Bennati, Michael Albasini, Jens Keukeleire, Edvald Boasson Hagen, Thomas De Gendt, Nikias Arndt, Sylvain Chavanel and Elie Gesbert.
Money on Boasson Hagen if he's still there in the final straight.
The peloton are almost exactly 10km behind.
Edvald Boasson Hagen is the only rider not doing too much in the front nine, knowing he could win the sprint even if the others make it back.
Increasingly looks like they won't make it though - the gap is out to 30 seconds.
Don't worry about the peloton right now - they are 10 minutes behind and rolling into an easy finish.
Those front nine now have a 17-second gap to the chasing 11.
Not 11 of those are chasing, though, as they have team-mate in the front split.
Ben Swift currently driving the 11 but not getting much help.
It's actually a 9 to 11 split at the front.
Here are the front nine: Jan Bakelants, Daniele Bennati, Michael Albasini, Jens Keukeleire, Edvald Boasson Hagen, Thomas De Gendt, Nikias Arndt, Sylvain Chavanel and Elie Gesbert.
Yep, Orica's Albasini duly goes and takes nine other riders with him, including team-mate Keukeleire.
Mollema is among the 10 to have missed the split.
Boasson Hagen has made it though.
Edvald Boasson Hagen is in fourth wheel.
If this break don't get rid of him, the rest are racing for second, perhaps Ben Swift aside.
The Orica Belgian goes - trying to tear the break apart and set it up for team-mate Michael Albasini.
The break is strung out but will come back together shortly.

Our commentary team of Simon Brotherton and Rob Hayles will talk you through the finale of today's stage 19.

Romain Sicard driving things at the front of the 20-man breakaway.
He's one of three Direct Energie riders in there so they have a few cards to play.
A reminder of all the 20 riders out front: Jan Bakelants (AG2R-La Mondiale), Daniele Bennati (Movistar), Bauke Mollema (Trek-Segafredo), Ben Swift (UAE), Rudy Molard (FDJ), Michael Albasini and Jens Keukeleire (Orica), Edvald Boasson Hagen (Dimension Data), Gianluca Brambilla (Quick Step), Robert Kiserlovski (Katusha), Thomas De Gendt and Tony Gallopin (Lotto-Soudal), Nikias Arndt (Sunweb), Julien Simon (Cofidis), Lilian Calmejane, Sylvain Chavanel and Romain Sicard (Direct Energie), Elie Gesbert, Romain Hardy and Pierre-Luc Périchon (Fortuneo-Oscaro).
Still a break of 20 riders.
Still 9'40'' or so ahead of the peloton.
Still Team Sky leading things to keep Chris Froome safe.
And I've still got love for this race.
Our intrepid team out at the Tour have been scouting out the finish.
There are a couple of sharp turns late on - including this one with around 450m to go...
...which leads into a downhill sprint.
Negotiate that corner and it'll be a rapid finish, right up Edvald Boasson Hagen's street, if the break don't drop him before.
Behind, the peloton are well clear of the Col du Pointu and, therefore, there are no more categorised climbs remaining for anyone in this Tour.
There is a slight bit of steep stuff in tomorrow's time trial but nothing too taxing.
The break are continuing to descent as they race through the town of Lauris.
The gap is out to around 10 minutes to the peloton so the break can afford to play a bit of cat and mouse in the final 30km.
Thomas de Gendt is sure to strike out early. It's just a question of when.
