The 20-man break are keeping their gap at around 7'30'' to the peloton.
A very straightforward day for Team Sky and Chris Froome so far - exactly what they were looking for.

The 20-man break are keeping their gap at around 7'30'' to the peloton.
A very straightforward day for Team Sky and Chris Froome so far - exactly what they were looking for.
A shot of Thomas Voeckler off the back of the peloton, grabbing a soft drink.
Not his day today. It's not been his Tour at all really.
It's also his final Tour before retiring - expect him to be allowed one final flurry on the attack in Paris.

Nicholas James: Do you think Rigoberto Uran, Romain Bardet or Dan Martin would have won the Tour if they swapped teams with Chris Froome?
Take it away, Rob Hayles: "Good question! The problem is that for some riders, Sky is not the best team for them. Froome obviously thrives there. Don't forget Uran has already ridden for them and didn't perform."

Into the final 100km of this monstrous stage - the break of 20 riders have eked the advantage back out to 7'27'' over the peloton.
Five-time champion Eddy Merckx is a guest of race director Christian Prudhomme in the car today, as is seven-time tennis grand slam champion Justine Henin.
Two Belgian sporting stars to mark their country's national day.
There are three Belgians in the break - Jan Bakelants, Jens Keukeleire and Thomas de Gendt - who will be gunning for victory today.

Christopher M Selby: How possible is it for GC to be contested in Paris?
Here's Rob Hayles with the answer: "It won't happen - for the same reasons as today. The GC will be done and dusted by the end of the time trial.
"That said, if there were two or three seconds in it, someone might try and have a go.
"But really that is unlikely because of the ceremonial etiquette for GC riders on the Champs-Elysees. Sunday will be all about the sprinters."

A reminder of those 20 riders out front: Jan Bakelants (AG2R-La Mondiale), Daniele Bennati (Movistar), Bauke Mollema (Trek-Segafredo), Ben Swift (UAE), Rudy Molard (FDJ), Michael Albasini and Jens Keukeleire (Orica), Edvald Boasson Hagen (Dimension Data), Gianluca Brambilla (Quick Step), Robert Kiserlovski (Katusha), Thomas De Gendt and Tony Gallopin (Lotto-Soudal), Nikias Arndt (Sunweb), Julien Simon (Cofidis), Lilian Calmejane, Sylvain Chavanel and Romain Sicard (Direct Energie), Elie Gesbert, Romain Hardy and Pierre-Luc Périchon (Fortuneo-Oscaro).
My picks from that bunch are Daniele Bennati, Edvald Boasson Hagen, Tony Gallopin and Lilian Calmejane.
Plenty of talent throughout, though. Set to be an intriguing run-in to Salon-de-Provence.
Now, this gap keeps coming down - the break of 20 riders are now 6'45'' ahead of the peloton.
It's a safe bet the break will accelerate again, though. This isn't a concerted effort by the peloton to bring them back.
Our BeSpoke team out at the Tour have endeavoured to explain as many of cycling's sometimes complicated terms during the race.

The gap had been out to eight minutes but the Team Sky-led peloton have started to cut into it slightly.
The 20-man breakaway now lead by 7'08'' with 121km remaining.

Simon Hawkins: Between Bardet and Uran's teams could they form a competitive breakaway of their own? 8 or 9 riders could work.
I've enlisted the help of Rob Hayles to field this follow-up, Simon - here are his thoughts:
"It would never work and even to attempt it would be futile. Team Sky would never allow it, they'd chase them down, and on this terrain Sky and the peloton would catch them in no time."

Serene progress for the 20-man breakaway as they eat up the kilometres in this middle section of the stage.
They have a lead of 8'07'' over the peloton.
Missed this but there was another abandonment earlier on - Czech rider Ondrej Cink of Bahrain Merida has left the race.
Barring heavy crosswinds or a remarkable, daring long-distance attack, this should be a comfortable day for Team Sky and Chris Froome.
The yellow jersey will of course be vigilant but yesterday's result was a massive step towards a fourth Tour title and third in succession.
How does this one stack up? Very well, according to Rob Hayles...

Paul Fawcett: Best rider - Michal Kwiatkowski (by far). Not in team's WhatsApp - Michael Valgren Anderson (Astana) after his comments about Fabio Aru.
Jemma Roe: Warren Barguill has absolutely had a stormer this tour - easily best rider - he's been so good to watch.
Josh Burgin: Best rider: Barguil. Biggest disappointment: Chaves. Futility jersey: Dan Martin. Rider not in whatsapp group: Cummings.
