The new GC top three
1. Tadej Pogacar
2. Primoz Roglic
3. Richie Porte
Your stage podium
1. Tadej Pogacar
2. Tom Dumoulin
3. Richie Porte
Roglic crosses the line
The yellow jersey looks distraught as he goes under the finish arch, collapses to the floor. Dumoulin is there immediately to try and console him.
This is one of the most dramatic moments we have ever seen in the sport of cycling.
Flamme rouge for Roglic
This is painful now. Roglic has lost the Tour, but he still has to finish the stage.
They think it's all over...
Pogacar wins the stage
And he's going to win the Tour de France.
Three kilometres to claw it back
Roglic has just 3,000m left of this stage to try and win back the lead in the Tour de France. He has MIguel Angel Lopez in his sights, which is more bad news for Lopez than good news for Roglic.
"Primoz Roglic is losing the Tour de France"
The words of Bradley Wiggins there as we watch Roglic's lead tumble away.
He's now 10 seconds behind on the virtual GC and he looks terrible on the bike. Pogacar, meanwhile, looks cool, calm and composed.
Bad bike change for Roglic
Gosh that's cruel. A very slow bike change for Pimoz Roglic has shed a few more seconds.
His 'cushion' is now 15 seconds and falling.
As we see Dumoulin crossing the line he has beaten Wout van Aert's time by 10 seconds.
Richard Carapaz just finished a few moments before, taking fourth overall on the timed KOM climb. That's not great for him, particularly if Pogacar can set the fastest time.
Good change for Pogacar
No major dramas there as the young Slovenian switched bikes. He has about 20 minutes of climbing ahead in whichc to gain back the remaining 25 seconds he needs on Roglic.
Porte is on the podium
...virtually speaking, that is. The Aussie has taken enough time already to leapfrog Lopez, he just needs to maintain that now as he tackles the climb of the Planche des Belles Filles.
We've just seen Porte change onto his road bike.
The gap now between Pogacar and Roglic is down to 25 seconds!
Pogacar still gaining time
The UAE Team Emirates rider is continuing to take time from Roglic. The cushion Roglic has is down to 30 seconds. The climb is still to come.
Dumoulin is losing time too, but to his team mate Wout van Aert. Since the Dutchman hit the climb, he has lost a bit of his time – but on paper he's still going to beat Wout's time.
No change for big Tom
The rangy Dutchman has not switched onto a road bike for this climb and he is grinding a massive, massive gear. His cadence looks really slow to me, but presumably the TT specialist and former Grand Tour champion knows what he is doing.
Dumoulin not to be left out
Big Tommy McWindmills is smashing this course and is currently running faster than his team mate, Wout van Aert.
Imagine if all three of the top places on the stage went to Jumbo-Visma. What a victory that would be for Bianchi, their bike sponsor.
Roglic has a bit of a cushion still on Pogacar, about 38 seconds at the moment.
Polka dots in the balance
Carapaz is about to start the climb which will decide whether he retains the polka dots tomorrow.
Dani Martinez was the fastest to climb it so far today. Pogacar would be the main threat to Carapaz, and he is due to begin the climb in about 10 minutes.
Van Aert in the lead!
Giving it absolutely everything on the final ramps of the climb, van Aert has just beaten Remi Cavagna's time by a whopping 28 seconds.
Rohan calls with aid!
Here's the Aussie TT specialist on how his team mate at Ineos can secure the polkadots today.
Dennis: The time trial tactic that could see Carapaz keep polka dot jersey
Not looking good for Landa
The Basque rider has lost 28 seconds already of that 51-second cushion on Enric Mas. He has only passed the first intermediate sprint at this point.
Richie Porte, meanwhile is having a good run. He's 11th overall at the first intermediate. He needs to do this course 99 seconds faster than Miguel Angel Lopez to get himself on the podium. It's looking promising.
We are hearing that Wout van Aert is clawing back the time he had given away at the first intermediate, but we haven't seen him on the TV pictures for quite some time. He might have timed this brilliantly, but the climb is still to come and those slopes are no joke!
Roglic on the road
Our yellow jersey is off the ramp and that means everyone has started the time trial. White jersey Tadej Pogacar needs to find a whole minute on Roglic if he is to overhaul him and seize the race lead, but that seems phenomenally unlikely, barring any mechanical mishaps.
Thibaut Pinot, meanwhile, is tackling the final ramps of the Planche des Belles Filles.
Alaphilippe home and dry
The Frenchman who wore the yellow jersey earlier in this race has brought it home some five minutes off the best times. He wouldn't really have expected to do much better than that to be fair, and that caps a strange Tour for the popular swashbuckler.
Mikel Landa, meanwhile, is off the ramp and we are now getting into territory that could change the complexion of the general classification top ten. The Basque is fifth, with a 51-second cushion to the next rider down, Enric Mas. Landa is not a good TTer, but he is a sublime climber on his day. II really couldn't guess what he'll do on this course!
Pinot changes bike
The Frenchman has no love for the aero machine and, while he's already lost enough time to rule him out of the stage win, he has now switched onto his road bike to tackle the Planche des Belles Filles.
The crowds continue to go crazy for him as he begins his uphill effort.
Wout down on first intermediate
The Belgian has ceded about 40 seconds to Cavagna over the first 14km.
Into the top 20
Our top 20 competitors are now rolling off the ramp. Nairo Quintana, never a celebrated tester, is on the course, as are Pello Bilbao the Spanish national champ and Sep Kuss, the all-conquering, col-crushing standout domestique of the Tour.
Richard Carapaz, resplendent in a custom polka dot aero suit, is also waiting in the wings. That's interesting because unlike any previous years, the polka dot jersey could be decided today in a time trial. Because the stage finishes with a climb, and a big one at that, it comes with King of the Mountains points at the summit.
We're expecting Carapaz to take it easier on the flat part of today's course, before swapping bikes and absolutely giving it the beans on the Planche itself. Tadej Pogacar, on the other hand, will have to do a big effort across the whole course – and may not have enough in the tank by the time he reaches the climb to beat whatever time Carapaz puts up.
It's a fascinating narrative within the main story and I for one have never been so enthralled by what the polka dot jersey wearer does in a time trial.
Belgian national TT champ, Wout van Aert, is off the ramp and ready to tear things up.
He has told the press already that his team Jumbo-Visma has given him freedom to chase the stage win today, so we should hopefully see a barnstorming performance.
Kawasaki on course
The man they call 'Kawasaki', Michal Kwiatkowski, is currently tackling the early part of the course. He's an outside bet for a result today, with a strong palmares and – of course – that first-ever stage win at the Tour a couple of days ago which can only give him confidence.
The crowds for are currently going mad for Thibaut Pinot, who is riding toward his home village right now.
We've seen a couple more sub-1 times, with Soren Kragh Andersen and Max Schachmann also sneaking under the bar. Neither was good enough to overhaul the amazing performance we saw from Remi Cavagna, who leads the day with 57:54.
French flags a'flying
Julian Alaphilippe is on the course now, while Thibaut Pinot waits for his moment in the starting house.
It has been another disappointing Tour for the Groupama FDJ leader, but as he stands in the blocks, the shouts of 'Pinot, Pinot, Pinot!' can audibly be heard through the TV microphones. The French do truly love him.
He is, of course, a local boy, and he might have dreamed of wearing the maillot jaune into this 'home' stage, had things worked out slightly better for him.
More painful moments
This one is an anguish with which many of us can identify. Unlike, say, trying to propel a £15,000 TT bike up a mountain – which for me at least remains a remote and nebulous concept like Kant's categorical imperative, the inalienable rights of man, or long division.
Keep 'em coming in via Twitter, gang.
Catalan rider David de la Cruz absolutely hurtled through the course and he has just busted the one-hour marker. He's the second rider only to manage that feat today.
His finishing time is good enough for a provisional second place and so Remi Cavagna can hold onto the hotseat for at least a little while longer. We've just seen some TV images of Wout van Aert warming up, however, and that might spell the end of Le Roi Remi's reign.
The daggers are out now...
For those just joining us on the live blog today, I asked you earlier on what's more painful than having to race an uphill time trial in the third week of the Tour de France. There have been some great answers exploring both literal and metaphysical pain, but this one might just be the cattiest response yet.
Well, it happened...
I'm off to make myself another coffee.
Meanwhile, in Luxembourg...
Just jumping over the border for a moment, here's the unfortunate Santiago Buitrago celebrating his 'win' a lap too early at the Skoda Tour of Luxembourg.
Whoops! - Santiago Buitrago celebrates a lap early by accident
Remi Cavagna is still the only rider to go sub one hour. He is a full two and a half minutes ahead of the next best competitor, and as such, the excitement has been rather neutralised for this part of the stage. His time is so fantastic that nobody else is getting close.
Thomas De Gendt is heading off the ramp now. Perhaps he can put the Belgian cat among the French pigeons?
How do you prep for a TT like this?
Let's ask one of most successful teams at this year's Tour de France...
First Brit home
Connor Swift is rolling up to the finish line now. He has had a whirlwind debut Tour de France and will certainly be feeling these final pedal strokes in his legs. From body guarding Nairo Quintana along the flat stages early in the race, to completing the last road stage at the Planche des Belles Filles, he has acquitted himself brilliantly. We'll see much more of this young Yorkshireman in this race in coming years, have no doubt.
The gap between the fastest and slowest times is about nine and a half minutes at the moment. As we've already said, if that gap swells to a gulf of 14 or 15 minutes, we will start to see riders eliminated on the final race day of the Tour. Brutal. Whoever cooked up this final stage was a truly Machiavellian sadist.
Pow, right in the feels...
David's answer to the question 'what's hurtier than a mountain time trial' has brought back some pretty tough memories of my time at primary school, handing in sub-standard homework to my beloved Year 6 teacher Mrs Hanks.
Cavagna's teamie, Kasper Asgreen, brings it home two-and-a-half minutes down on the leader, but that time is still good enough to take second on the provisional stage results – such is Cavagna's lead.
Cavagna is over the line
It really is an absolutely heinous finish, this, with really steep gradients in the final kilometre.
Undeterred by that, however, is the French national time trial champ who has smashed the previous best time for today held by Nils Politt by a thumping margin of three minutes and five seconds. That makes him the first rider to go under the hour mark on this brutal course.
That is an unbelievable performance from the Deceuninck Quick-Step rider and he'll be in the hotseat for a little while, I'd wager. Notably, he did the whole course on his TT bike. Wonder if the GC guys will take the same approach?
Cavvin' it Large
Goodness me, Cavagna has now caught Tony Martin, his three-minute man. The rider the French call 'the TGV' is absolutely walloping this course.
A father's love...
A parent's love for their child is unconditional, supposedly, but Shaun has suggested one thing a kid can do to REALLY put that affection to the test.
More painful than an uphill mountain time trial, though? I'm not sure. Compared with this hour-long trip to the pain cave, a little bit of foot pain is surely a trifle.
Keen to hear some more of your answers to this question!
Cavagna giving it the big hoon
It appears our first serious contender today is not Tony Martin, but rather Remi Cavagna. The Frenchman is absolutely flying through this course and has the best time at the first intermediate by 17 seconds. If he can sustain the effort when the steep gradients of La Planche kick in he's on for a great time.
Kluge crosses the line...
He's home in 01:04:25 and that profoundly middling time should be enough to secure the lanterne rouge going into tomorrow.
Interestingly, he rode his TT bike the whole way up, while his team leader Caleb Ewan, battling for survival tomorrow, switched onto a road bike.
It's rather rare to be caught outside the time cut on a time trial, but it's also rare that a time trial goes up the Planche des Belles Filles.
Eurosport expert, Brian Smith, says today the time cut will be about 13 to 14 minutes, so whichever time is set by the winner, add 15 minutes onto that and you have a guide as to the sort of area we'll be in.
The likes of Caleb Ewan and Sam Bennett, who are no specialists in this discipline and have been going through hell this week already in the Alps, will have to strike a perfect balance between conserving energy for the Champs Elysees tomorrow and actually making it to tomorrow.
What's more painful than a time trial uphill? I suppose this answer was inevitable...
While this one certainly sounds like it would smart a bit.
Der Panzerwagen Ist Unterwegs!
Sorry for my terrible German. Tony Martin is off the ramp and he might provide us with an early marker of what a good time looks like.
He's not historically been a massive fan of time trials that go up mountains, so don't hold your breath about any fireworks just yet.
Also on course are Kasper Asgreen and Remi Cavagna, both national champions of their respective countries.
So for those who actually do try and win this today, it will be an incredibly painful experience lasting just under an hour. How hurty? It's impossible for us normal humans to really understand, but I would speculate that it's marginally less painful than having a root canal.
What do you think? What's hurtier than an uphill TT?
To change or not to change
The unique feature of today's course is the fact that the first half is pan-flat, while the second half is quite a testing climb that has provided the summit finish to a stage of the Tour on more than one occasion, the Planche des Belles Filles.
There are a lot of questions on whether the fastest riders will change bikes at some point, in order to switch from the generally heavier but more aero TT bike onto something a bit lighter and racier.
If you really fancy nerding out on some TT variables, former British champion, Alex Dowsett, has created an absorbing thread on Twitter.
Well here we are again, sports fans...
A time trial in the Tour de France. Just when you think you're out, they pull you back in.
The race could be decided today, with Roglic and Pogacar rolling down the start ramp muuuuch later. At the moment we're seeing the heftier chaps who've been battling for the lanterne rouge glasscrank their way along the course. Sam Bennett has opted for the all-green skin suit, making him look like a gigantic garden pea. Nobody is really trying, for the sprinters and domestiques today is very much about survival, conservation and enjoying the last stage before Paris.
Wiggins: Reza’s comments highlight how backwards cycling is
Bradley Wiggins has praised Kevin Reza for speaking out about cycling’s silence surrounding racism and diversity.
In a powerful interview with Eurosport’s Orla Chennaoui, Reza said that the sport had a "lot to learn" and urged his fellow professionals to wake up to the issue.
"I think it’s a very brave thing what Kevin Reza has done and I know he doesn’t want to become a face for it, but the tragedy of the whole thing is how backwards this sport is in many ways," said Wiggins on The Breakaway and subsequently on his podcast.
The people in power focus way too much on issues that are way beneath issues like racism. It needs addressing, it has to start at the top and I think there is incompetence at the top of the sport, there is a power position and nothing that qualifies them to be in that position.
‘Look at your belly button less’ – Kevin Reza calls on white riders to address racism
Stage 19 recap - Kragh Andersen wins again on Stage 19, Bennett takes giant step towards green
It was double delight for Denmark's Soren Kragh Andersen at the Tour de France on Friday after the Sunweb rider soloed clear of a select move to take a second victory on Stage 19 at Champagnole. Sam Bennett all but secured the green jersey while there was no change at the top as Primoz Roglic retained the yellow jersey.
Kragh Andersen picked up his second Tour stage win in a week with an emphatic solo victory from a strong 12-man break after the rolling 166.5km stage into the Jura.
The Danish powerhouse surged clear of a move containing green jersey rivals Bennett, Peter Sagan and Matteo Trentin with 15km remaining. And with the chasers unable to join forces behind, the 26-year-old held on to secure his Sunweb team's third victory of the race.
