What an incredible stage that was - did anyone really, truly believe Primoz Roglic would lose the yellow jersey?
Maybe only Tadej Pogacar did. And that's all that mattered - the 21-year-old produced one of the best rides in Tour history to take over the race lead in a stunning finale.
He will be crowned Tour champion tomorrow as the race reaches it's last stop - Paris.
Join me then for live coverage of the final stage of this spectacular Tour.
For now, the report of Pogacar's dramatic victory is here.
So that's the only jersey Tadej Pogacar won't be winning in Paris.
Ireland's Sam Bennett leads Peter Sagan by 55 points in the green jersey, with 70 points maximum left on offer tomorrow - 20 at the intermediate sprint and 50 at the finish.
Bennett just needs to stay close to Sagan at the intermediate sprint and ideally maintain a lead of over 50 points after it.
Then he can happily freewheel at the back of the pack and still win green, even if Sagan wins the stage.
But I'm sure Bennett will be hugely motivated to win on the Champs-Elysees.
Not many riders win the last stage in green - Mark Cavendish was the last to do so in 2011.
Points classification after stage 20
1. Sam Bennett (Ire/Deceuninck-Quick-Step) - 319 points
10, Michael Morkov (Den/Deceuninck-Quick-Step) - 129

Miguel Angel Lopez had the second most miserable day after Primoz Roglic.
The Colombian started the stage third overall, 1min 28secs ahead of Richie Porte, but crumbled on the time trial.
He not only lost his podium place to Porte but also then dropped below Mikel Landa and Enric Mas to end up sixth overall.
Post update
Britain's Adam Yates ended up slipping two places to ninth overall.
It was also going to be a tough ask - time trials are not his specialty and he had Rigoberto Uran and Tom Dumoulin lurking.
Still, having been ill in the build-up to the race, Yates should be pretty pleased with his showing - four day in the yellow jersey and ninth on GC. Though that first stage win still eludes him.
It'll be intriguing to see where his career goes when he joins Ineos next year.
Post update
Tadej Pogacar is guaranteed to win the polka dot jersey because there is only one point available on tomorrow's stage.
He will also win the white jersey as the best young rider on general classification.
Because he's also the best rider of any age on GC.
You see the same rider winning three of the four jersey and assume he absolutely dominated the race.
But controlling it all the way through doesn't matter at all if you lose it at the last.
And as much as Primoz Roglic lost it, Pogacar went out there and won it today.
Also - incredibly, that stat about the yellow jersey changing hands every time the Tour has visited La Planche des Belles Filles held true again.
Mountains classification after stage 20
1. Tadej Pogacar (Slo/UAE Team Emirates) - 82 points
2. RIchard Carapaz (Ecu/Ineos Grenadiers) - 74
3. Primoz Roglic (Slo/Jumbo-Visma) - 67
4. Marc Hirschi (Swi/Team Sunweb) - 62
5. Miguel Angel Lopez (Col/Astana) - 51
6. Benoit Cosnefroy (Fra/AG2R La Mondiale) - 36
7. Pierre Rolland (Fra/B&B Hotels-Vital Concept) - 36
8. Richie Porte (Aus/Trek-Segafredo) - 36
9. Nans Peters (Fra/AG2R La Mondiale) - 32
10. Lennard Kamna (Ger/Bora-Hansgrohe) - 27
Post update
After cruising through the start of the stage and saving himself for that final climb, Ineos' Richard Carapaz actually failed to post the one of the six fastest times up La Planche des Belles Filles.
As a result he didn't pick up any king of the mountains points and lost the polka dot jesery to the voracious Tadej Pogacar.
Post update
There are plenty of other incredible young riders coming through as well of course.
It's been a long time since young riders were allowed to win big races and it's been happening more and more in recent years.
When doping dominated cycling, it was older, most established riders who tended to win as the use of PEDs led to a hierarchy in the peloton.
Of course questions still need to be asked and only the riders themselves know if they are clean. But young talent coming through is a promising sign.
Post update
I'm sure Primoz Roglic will be back next year but it feels like he will never have a better chance.
Roglic is 30.
Tadej Pogacar turns 22 in two days and UAE Team Emirates will surely put a better team around him next year. Not that he perhaps needs it, having ridden most of the major climbs alone or just with David de la Cruz this year.
Egan Bernal is 23 and backed by the richest team in the sport, who will also look to strengthen for next year.
Chris Froome might have something to say about this, but it really feels like Pogacar v Bernal will be the battle for the next few Tour titles.
Post update
Poor Primoz Roglic has to try and put into words what just happened.
Speaking to ITV4, Roglic said: "I just didn't push enough. It was like that. I was more and more without the power I needed but I gave it all until the end.
"We'll see what happens next. I can be happy with the racing we showed here so let's take positive things out of it."
Post update
More from Porte on Pogacar beating Roglic: "No I don't see that coming. Those are two great guys.
"Pogacar is a huge champion and it's going to be interesting with Bernal next year - they are the future of the sport. It's going to be a fantastic tussle next year. The ride Pogacar did today is incredible."
Post update
Richie Porte, speaking to ITV4: "I didn't think this race was going to happen because of coronavirus.
"Me being me I missed the birth of my second child to be here - my widfe told me to go and if she saw me at the back she'd be upset so I wanted to do well.
"This is sweet. Me on the podium in Paris is a photo I'll have on the wall after I retire. It's been so many years of disappointment and crashes. We had our dramas here too so to come away with third is fantastic.
"It's no secret I'm leaving Trek but the way they've got around me this year has been brilliant. Just incredible."

A huge chapeau to Richie Porte for finishing third overall.
The Australian has had more than his fair share of mishaps over the years when looking on course to challenge for the title. He always also seemed to just have that one really bad day.
But at 35 he's ridden the best Tour of his career, beating his previous best finish of fifth.
It was a sublime ride today, paced perfectly. He seemed to be a bit off the pace on the flat but was just keeping plenty in store to blast up the final climb.
Porte is set to join Ineos next year so this was likely his last chance to lead a team at a Grand Tour and he delivered.
Post update
UAE Team Emirates were certainly prepared for Tadej Pogacar to take the yellow jersey at some point.
They had a yellow facemask to match made up, which the 21-year-old is now sporting on the podium.
Post update
Those GC standings will not change tomorrow as tradition dictactes that the final stage into Paris is ceremonial and the race leader is not attacked.
So Tadej Pogacar has won the 2020 Tour de France by 59 seconds over Primoz Roglic, having started the day 57 seconds back.
Incredible.

Tour de France champion Tadej Pogacar: "I'm really proud of the team, they did such a big effort. We were dreaming of the ywllow jersey from the start. Amazing.
"It was not just me today, we needed the whole team for the recon. I knew every corner and knew exactly where to accelerate. Congrats to all my team.
"I didn't hear anything on the radio in the final 5km because the fans were too loud so I just went full gas.
"My dream was just to be on the Tour de France and now I've won it. It's unbelievable."
Post update
The last place on earth I'd like to be tonight is the Jumbo-Visma hotel.
The strongest team in the race, they controlled everything superbly to put their leader in a fantastic position to deliver today.
