This time trial stage has left pundits guessing about who will benefit most.

It has elements that will favour the pure time triallists, but there will be a few all-rounders that will fancy a tilt at a decent time.

There are two climbs - right at the start and up to the finish.

It's certainly a test for the yellow jersey contenders one day after going up Mont Ventoux - especially those who jogged up part of it.

Seb Piquet from Tour de France race radio has spoken to BBC Radio 5 live about the atmosphere on today's stage.

"The Tour is a symbol of people linked together – families on the side of the road, old people and young people from every origin to enjoy the show and the summer of France.

"The atmosphere was very heavy at the start and finish this morning. There will be another minute of silence at the podium presentation. There is no music – it’s a completely different atmosphere from what we are used to at the Tour de France."

Tom Dumoulin is not hanging around. He's through the third checkpoint and has a 56-second advantage on leader Nelson Oliveira. Can he open up that gap more before he reaches the finish line?

Riders have been reacting to yesterday's terror attack in Nice.

Tom Dumoulin looks set to take the lead on today's stage, but he tweeted this morning, as has yellow jersey contender Bauke Mollema and race leader Chris Froome.

Bauke Mollema: I couldn't sleep yet and now read about something more important than the Tour. My thoughts are with the people of Nice.

Tom Dumolin is on course to be the quickest man of the day, going through top of the board after 17.5km.

We talked about Thibaut Pinot's retirement from the race through illness.

There's a couple of other withdrawals to mention.

Simon Gerrans broke a collar bone in his fall on an ascent yesterday.

We've also lost Edward Theuns, who crashed this morning.

Thomas Dumoulin comes through the 7km checkpoint quickest - he's gone 10 seconds swifter than Nelson Oliveira did at the same point.

The only Briton to have made a mark on today's time trial so far has been Steve Cummings - he's sixth, 53secs off leader Nelson Oliveira.

The rest are as follows - Ian Stannard (74th), Luke Rowe (93rd), Mark Cavendish (116th) and Dan McLay (115th).

Tony Martin will have to wait for his sixth Tour stage win - he crosses the line in fifth place with a time of 52mins 20secs - 34secs behind leader Nelson Oliveira.

Be French, meet together, celebrate, love one another. And never give up. My thoughts are with Nice. 

Horrible images from what happened in Nice last night. My solidarity goes out to the French people.

Meanwhile, Tony Martin has upped the pace and comes through the third checkpoint, 9.5km before the finish, in fourth. 

He needs to find about 25 seconds from somewhere.

Tom Dumoulin, who is handy on a time trial, is down the ramp and on the road.

The Dutchman is a world time trial bronze medallist in 2014 and you'll remember he won stage nine on this year's Tour.

I've been walking about the finish area and it is not obvious that there is a significantly heightened police presence.

Apart from the fact we were asked if we had any knives or guns on us at the bag check, it was business as usual.

If anything the mood was less one of panic and anger but more one of a subdued resignation. It's worth pointing out a number of ASO officials (Tour de France organisers) are wearing black armbands.  

Tony Martin remains sixth as he comes through the second of the three timing checkpoints at 17.5km - he's now 41secs off the pace.

The 2011, 2012 and 2013 world time trial champion Tony Martin is on the road.

The London 2012 silver medallist is through the first checkpoint in sixth place - 34 seconds off the pace.

Thibaut Pinot tweeted about his race retirement - but also paid tribute to the victims in Nice.

He said: "I am leaving the Tour but there are worse things happening out there. How can you kill innocent people on the Bay of the Angels."

Disappointing news - for the man himself and spectators - as Thibaut Pinot withdraws from the Tour de France.

He's France's national time trial champion and would have been a contender on this stage.

The 26-year-old FDJ rider looked off the pace yesterday, getting dropped by the yellow jersey group a couple of times.

It turns out Pinot was ill, and this morning he called time on this year's Tour.

"In practice not much has changed today. The only difference was we were asked if we had a weapon on us and our bags were searched more thoroughly. The organisers did consider the cancellation but the race continues in dignity."

The Tour de France's official Twitter account posted: "The heart of the Tour beats for Nice."
