Bardet beginspublished at 15:28 British Summer Time 15 July 2016
We're into the top five as Romain Bardet - 1min 15secs behind Chris Froome in the GC - launches into his time trial.
He's not a renowned time trialist the Frenchman - it could be about damage limitation.

Former GB cyclistWhen these gusts of wind hit you they can pull you right across the road and you don't want that. There are a few riders, certainly some of the lighter riders, have gone with a lighter wheel so there's less surface area for the wind to catch.

Chris Froome is getting warmed up on a static bike, pumping the legs in the French sun. He'll be last on the road from 15:39 BST.
Dan Martin and Fabio Aru are the latest off the ramp.
Where's Wilco?published at 15:20 British Summer Time 15 July 2016
Not great for Wilco Kelderman, who is down in 33rd after the second checkpoint.
He is LottoNL's general classification man but he's way off the pace today.

It's not just the Tour de France that has been marking the events in Nice.
At the Open Championship at Royal Troon, the French flag was flown at half mast, and players wore black ribbons as a mark of respect to victims of the attack in Nice.

Here goes Richie Porte, no doubt keeping an eye out for motorbikes.
He shouldn't have to worry about encroaching fans today, mind.
The Australian is 2mins 22secs behind yellow jersey holder Chris Froome.
Nibali homepublished at 15:07 British Summer Time 15 July 2016

Former GB cyclistAfter what happened yesterday in the race – all that was put to one side and hey, it's just a bike race and it doesn’t matter in the big scheme of things. When they’re out there the riders will be fighting for everything they can get. It will certainly be more sombre surroundings today.
Kudos to De Gendtpublished at 15:01 British Summer Time 15 July 2016
Image source, ReutersSpeaking of Thomas de Gendt, we should mention how brilliant his victory on yesterday's stage was.
The Belgian went with an early breakaway and, after looking like he had been dropped, returned to win.
His performance was lost somewhat in the mayhem when Chris Froome, Richie Porte and Bauke Mollema were brought down by a motorcycle.
There was also Froome's jog up a mountain - I'm sure you've seen it by now.
De Gendt done, Geraint startspublished at 14:55 British Summer Time 15 July 2016
Yesterday's stage winner Thomas de Gendt is done for the day. He finishes in 54mins 23secs - 4mins 8secs off the lead.
That gives you an idea how good Tom Dumoulin's time was.
Meanwhile, Team Sky's Geraint Thomas is out the blocks and on his way.

Watch the windpublished at 14:46 British Summer Time 15 July 2016
Quite a few riders have come off today's course and made sure we know how windy it is.
They have a point though - there are gusts of up to 60km/h. There's a head wind on that initial climb and then a lot of crosswinds to deal with.

That will be tough to beat.
