Hello and welcome to live coverage of stage 19 of the Tour de France - a rolling 222.5km stage from Embrun to Salon-de-Provence, the longest of the 104th edition of the race.

Julien Vermote (Quick-Step Floors), Marcus Burghardt (Bora-Hansgrohe), Pierre Rolland and Dylan Van Baarle (Cannondale-Drapac) and Maxime Bouet (Fortuneo-Oscaro) bridge over so we have eight riders ahead now.

Adrien Petit (Direct Energie), Michael Albasini (Orica) and that man van Keirsbulck (Wanty) have managed to edge ahead.

Thomas De Gendt alert: the indefitigable Belgian is on the front again... surely he can't be eyeing up another breakaway? You'd think he'd be on duty for Lotto-Soudal sprinter Andre Greipel today. The German has had a rotten Tour but still has two chances - today and in Paris on Sunday.

We have about a dozen riders off the front of the pack now as they ride alongside the Lac de Serre-Poncon. But with Team Sky coming to the front of the pack, it doesn't look like this one will stick.

Here's what the riders have in store today: three categorised climbs, some rolling roads and - what you can't see in the profile - likely winds towards the end. This race is not over yet!

Guillaume van Keirsbulck (Wanty-Groupe Gobert) finds himself out in front alone after the initial attacks came to nothing. You may remember the Belgian from that stage to Vittel, where he stayed out for more than 200km solo before being reeled in ahead of the controversial scenes in Vittel, where Arnaud Demare won as Peter Sagan and Mark Cavendish clashed in their last turns of the pedals in the race (Cavendish withdrew injured and Sagan was booted out).

The familiar sight of Christian Prudhomme waving the flag from the back of his red Skoda signals the start of this intriguing stage... and there's a flurry of attacks from the outset.

Twenty seconds passed before a battling Darwin Atapuma – denied a win on Colombia Day – just held on for second place ahead of Romain Bardet (Ag2R-La Mondiale), the Frenchman edging British defending champion Chris Froome (Team Sky) for third place and four vital bonus seconds. With Colombian Rigoberto Uran (Cannondale-Drapac) crossing the line two seconds back for fifth place, Bardet rose to second place in the general classification – 23 seconds behind Froome – with Uran now 29 seconds off the summit.

Yesterday, Frenchman Warren Barguil made Tour de France history in becoming the first man to win atop the legendary Col d’Izoard in an explosive Stage 18 that saw Romain Bardet move four seconds closer to Chris Froome’s yellow jersey with three days of the race remaining.
