There is heightened security around today's stage and a minute's silence was held in Bourg-Saint-Andeol before the first rider, Sam Bennett, went down the start ramp at 09:05 BST.

There will also be no PA system announcements or music played at the start and finish - effectively silence.

There was, understandably, doubt about whether today's stage would go ahead following events in Nice.

But Tour organisers decided to let racing continue.

"We want this day to be a day of dignity as a tribute to the victims," said race director Christian Prudhomme.

"We had a crisis meeting with the prefect of the Ardeche department and the gendarmerie. The stage is on. The race must continue."

Jerome Coppel, the 2015 French national time trial champion, comes in a shade under Nelson Oliveira's time - four seconds to be precise.

So that moves him into second.

Before we assess the mood around the Tour today and take a closer look at the stage and the main contenders, I'll quickly bring you up to date with the current leaders.

The riders go out in reverse order of the general classification standings - so Chris Froome is last at 15:39 BST, just after fellow Briton Adam Yates at 15:36 BST.

Portuguese national time trial champion Nelson Oliveira is top of the time charts, coming home in 51mins 46secs.

He usurped Australia's national time trial champion Rohan Dennis, who is 10secs behind.

Britain's Steve Cummings, who won stage seven, is third, 53secs off Oliveira.

This could all change, though, as France's Jerome Coppel is currently on a very quick run and has gone quickest through the final check point.

Hello and welcome to stage 13 of the Tour de France, the 37.5km individual time trial from Bourg-Saint Andeol to La Caverne du Pont-d'Arc.

The mood is sombre on the Tour today, following the attacks in Nice.

We shall reflect on how the riders and organisers have been paying tribute to the victims as well as keeping you across the events of today's stage.
