Tadej Pogacar is a force of nature. But how will he ride this Tour, given he's likely to be in yellow before long, instead of nabbing it at the end like last year?
He'll probably take it in his stride on this showing.
The report of stage five is building here.
We'll be back with live coverage of stage six - one for the sprinters - tomorrow.
Later.
"I rode the best TT I could. I went out conservatively, maybe too conservatively, but it's just what I had," Geraint Thomas told ITV4.
"I didn't feel 100% but I don't want to bang on about that. I tried to do what I could and it wasn't enough.
"It was decent pace but not enough power. I didn't know what to expect, I woke up this morning and felt terrible but once I got going it was better. I've just to crack on and deal with it."
"Today was a really good day for me, luckily I had perfect conditions," said Tadej Pogacar.
"I checked out the course because last the few TTs I made mistakes starting too fast but here I paced myself well and did a perfect rhythm to the end.
"The goal was not to lose time but I gained time so I'm super happy and excited for the whole Tour.
"I would love to have the yellow jersey but it also looks super nice on Mathieu!"
So Tadej Pogacar moves up to second overall, now eight seconds down on Mathieu van der Poel.
Tadej Pogacar not only wins stage five but also makes a massive statement in the defence of his title.
Tremendous racing from Mathieu van der Poel.
He finishes fifth in the TT and loses 31 seconds to Tadej Pogacar.
It's enough to keep the yellow jersey by eight seconds.
They are the two big winners today. For most others, it was just about limiting losses.
Mathieu van der Poel gets out of the saddle and sprints.
Sheer agony on his face.
He's going to defend the jersey though.
Pogacar will win the stage.
Yellow jersey claimed too? It's going to be so tight.
Van der Poel has 1km to go and only five seconds on Tadej Pogacar left.
Julian Alaphilippe loses 1:10 to Tadej Pogacar at the finish.
MVDP has about seven seoncds on the road to keep the yellow jersey, with 2km to go.
The last bit of major intrigue today - can Van der Poel hold off Pogacar to retain the yellow jersey?
He's got 17 seconds to play with over the final section.
Wout van Aert finishes in provisional fourth place - 30 seconds slower than Tadej Pogacar, who will move above him in GC.
Wout van Aert is into the final 2km of this TT. He was aiming for a stage win and the yellow jersey today. It looks like he'll get neither.
Tadej Pogacar has just put 1:18 into Geraint Thomas today.
Tadej Pogacar has just marmalised the time of TT specialist Stefan Kung.
The Slovenian records 32:00 - beating Kung's mark by 18 seconds.
That's the stage win secure, barring a miracle from the rest.
Does it also put him in yellow today?
Mathieu van der Poel goes through the second check fifth fastest, 22 seconds back on Tadej Pogacar.
He started the day with a gap of 39 seconds over the Slovenian.
This is going to be tight.
