Bye for now

Geraint Thomas is on the podium ready to receive his first ever Tour de France yellow jersey.

That's my cue to head off and pick the bones out of that stage for the report, which is building here.

Phew. What a day. Hope you can join us when we do it all again tomorrow. Can Mark Cavendish make it back-to-back British stage wins?

For now, farewell.

'I was a little bit petrified'

GC contender Richie Porte, speaking on ITV4: "Keeping it rubber-side down was the goal. Before I went out, I followed Nicolas Roche in the car and he binned it so I was a little bit petrified. It was such a slippery course.

"I would have liked to be a bit quicker but wanted to keep all the skin in tact. I took no risks and that was the way to ride it."

'I didn't even dream of this'

Geraint Thomas, speaking on ITV4: "It is unreal, it is the start of my eighth tour and it is my first stage win. I didn’t even dream of this last night. Wow, it is unbelievable, I am lost for words.

"I have a tendency to go out hard but I am getting older now and learning to pace myself. It couldn’t have gone any better."

Absolutely incredible

Rob Hayles

Former GB cyclist on Radio 5 live sports extra

Absolutely incredible ride from Geraint Thomas, nobody saw that coming, not even the TV director!

What a day for Thomas

Simon Brotherton

Radio 5 live sports extra commentator

It was set up for Tony Martin in front of his home crowd but Geraint Thomas has taken it from him in his back yard.

The yellow jersey will be on Thomas' shoulders tonight for the first time in his career. What a day for Team Sky and what a day for British cycling!

BreakingTHOMAS TAKES THE YELLOW JERSEY

Did anyone see this coming? The TV director didn't, having not bothered to follow Geraint Thomas for any part of his ride.

When they did pick him up, the Welshman was flying across the finish line in a belting time of 16 minutes four seconds, which proved enough for him to win his first ever grand tour stage.

Not a stage you'd have bet on him winning, even if he's always been a good time trial rider.

Thomas will be in yellow for the first time tonight. Team Sky have laid down yet another imposing marker.

Froome finishes, Thomas wins

He's not got it...Chris Froome comes home in 16 minutes 16 seconds - 12 seconds behind team-mate Geraint Thomas, who takes his maiden grand tour stage win.

That's a great time for Froome though, taking crucial seconds on his GC rivals.

The last rider on the road, the defending champion, Chris Froome is into the final stages...

Froome v Thomas?

Rob Hayles

Former GB cyclist on Radio 5 live sports extra

Chris Froome is riding to clockwork as it stands, comfortably ahead of Porte and Quintana.

His biggest rival at the moment in terms of general classification is teammate Geraint Thomas!

Quintana finishes

Nairo Quintana posts 16 minutes 52 seconds.

That's a very solid ride from the Colombian climber, not least having seen his team-mate Alejandro Valverde crash out.

Meanwhile, GC contender Fabio Aru has just posted 16 minutes 56 seconds.

Alberto Contador comes through in 65th place, just waiting for a confirmation on time.

Thomas had psychological advantage

Rob Hayles

Former GB cyclist on Radio 5 live sports extra

Geraint Thomas looks like he left a bit more in the tank for the end and he had the psychological advantage of having Romain Bardet right in front of him – he had a carrot to chase.

Kung goes second

Stefan Kung cannot better Geraint Thomas either!

The Swiss BMC Racing Team rider comes home five seconds behind the Welshman.

Only Chris Froome can deny his team-mate the yellow jersey now and that's looking unlikely...

Froome through the checkpoint

There remains a big threat to Geraint Thomas out there in the shape of Stefan Kung of BMC.

He was just one second off Tony Martin at the checkpoint.

Chris Froome has just gone through that checkpoint in nine minutes 28 seconds. That's five seconds off where Geraint Thomas was.

Ooo-er, slip for Nairo Quintana, but he just about keeps it upright.

The Colombian needs to stay upright and come in around the 17 minute mark to limit his losses.

Geraint Thomas effectively took 12 seconds on Tony Martin in the second half of this time trial.

Staggering.

As it stands

  1. Geraint Thomas (Team Sky) 16mins 4secs
  2. Vasil Kiryienka (Team Sky) +7secs
  3. Tony Martin (Katusha-Alpecin) +8secs

Martin doesn't topple Thomas

Rob Hayles

Former GB cyclist on Radio 5 live sports extra

I’m speechless! Did Tony Martin take it too easy on the bends? Was Geraint Thomas too good? Probabaly a bit of both.

Martin goes third

Tony Martin could not even take second as he slots in behind Vasil Kiryienka and into third.

It's a Team Sky one-two at the moment and Geraint Thomas is looking very good for his first Grand Tour stage win.

Balancing act for Froome

Rob Hayles

Former GB cyclist on Radio 5 live sports extra

Chris Froome has to attack the straights and back off on the bends. Err on the side of caution.

There is plenty of time for Froome to gain time on his rivals later on as long as it isn’t too big a gap – it is a fine balancing act.

Thomas stays first

No! Tony Martin, the home favourite, fades in the final stages and does not better Geraint Thomas' time.

Waiting for confirmation of Martin's time to see if he grabbed second.

Taylor Phinney, who was forced to pretty much learn how to walk again after a horror crash, has just posted a mightily impressive time of 16 minutes 21 seconds

Geraint Thomas still has top spot. Can Tony Martin beat him?

Tony Martin has posted the fastest time at the checkpoint, going through at nine minutes 19 seconds.

Is the German on course for a home victory?

Froome is off

The defending champion is under way...

Valverde abandons

Rob Hayles

Former GB cyclist on Radio 5 live sports extra

It looked like a bad lower limb injury for Valverde and it has proved to be the end of his Tour.

BreakingValverde abandons

Confirmation of what was expected after that awful crash, but Alejandro Valverde has officially abandoned the Tour de France on stage one.

The 37-year-old Spaniard crashed heavily into the barriers after misjudging a tight corner in wet conditions and was unable to get back to his feet.

An outside chance for the overall title, Valverde was also due to play a key support role for one of Chris Froome's main rivals Nairo Quintana.

Porte finishes

Richie Porte, perhaps sensibly, opts for safety as he comes through in a time of 16 minutes 51 seconds.

That's on a par with the likes of fellow GC riders Dan Martin, Thibaut Pinot and Romain Bardet.

A solid, if unspectacular, ride but will any of the main overall contenders risk pushing it too far in these conditions?

Every second is vital but a big crash could end your Tour.

Thomas crossing the line

Well the TV coverage completely missed Geraint Thomas' ride but here he is crossing the line earlier.

His time of 16 minutes four seconds is yet to be beaten, but the favourites are out on course.

Right, while we await more news on Valverde, today's heavy favourite Tony Martin has just got his ride under way.

The four-time world time trial champion is riding a specially branded Kraftwerk bike, the German band having formed in Dusseldorf.

Will he take the first yellow jersey of this Tour de France?

Tour over for Valverde?

Rob Hayles

Former GB cyclist on Radio 5 live sports extra

That looks like a leg or an ankle that Valverde has gone hard into the barriers with. He was going very quickly and he looks to be in considerable discomfort. His Tour might be over.

He hit the barriers so so hard. They tried to move him but he wasn't getting up.

It's a really ugly looking crash for Valverde. He went at the corner full pelt, his wheels went from under him and he was thrown forward off his bike and into the barriers.

If he is forced to abandon it would also be a big blow to Movistar team-mate Nairo Quintana's chances.

Valverde down

Potentially a huge moment in this Tour de France on stage one.

Alejandro Valverde has fallen heavily on the corner that has proved hazardous for many riders all day.

The Spaniard is still down. It looks like his Tour could be over.

Countdown to Froome

We're just under 20 minutes away from Chris Froome starting his Tour de France title defence.

What are the chances he can make it three straight and four titles in five years?

We've got you covered.

Peter Scrivener attempts to answer that very question here.

And our chief sports writer Tom Fordyce has been to meet Froome to get inside the mind of a climber.

As it stands

  1. Geraint Thomas (Team Sky) 16 minutes four seconds
  2. Vasil Kiryienka (Team Sky) +7secs
  3. Matteo Trentin (Quick-Step Floors) +10secs

Thomas on top (so far)

Geraint Thomas was actually three seconds behind Vasil Kiryienka at the halfway stage but produced a negative split to take the top spot.

Here goes Alejandro Valverde...

Another of Chris Froome's rivals, Richie Porte, is out on the road...

Crunch time.

Top ride from Thomas

Rob Hayles

Former GB cyclist on Radio 5 live sports extra

Oh my word! The French TV directors have missed all but the end of his ride but Geraint Thomas has gone quickest. Is he back to his best? Well, he is currently seven seconds ahead of anyone else.
