Bonjour le Tour! Hello and welcome to live coverage of Stage 7 of the Tour de France - at 230km it's the longest of the race.

No change in the general classification with Giulio Ciccone retaining his six-second lead over Julian Alaphlippe. Peter Sagan keeps hold of the green jersey - and indeed extends his lead over Michael Matthews.

The Dutchman Dylan Groenewegen (Jumbo-Visma) launched early and just kept Caleb Ewan (Lotto Soudal) at bay as the road ramped up slightly towards the line. Peter Sagan (Bora-Hansgroghe) third ahead of Viviani, Colbrelli and Jakobsen, I think.

Victory for Dylen Groenewegen! Just! A photo finish with Caleb Ewan!

Morkov and Richeze now leading out Viviani, with Sagan and Ewan just behind...

Under the flamme rouge and it's Bora's Daniel Oss on the front - and some argy-bargy from Groenewegen further back...

They negotiate the sweeping left-hander and now are on the long straight all the way to the line along the river.

Van Aert pulls off after a huge shift, passing baton on to Jansen, who has two Bora riders in his wake.

They pass under the magic 3km mark which should see the sprinters now come to the front with their trains. But it's all strung out - and Geraint Thomas is still right in fifth wheel or something.

Jumbo-Visma back on the front with Martin, or is it Van Aert?

Now QuickStep have come to the front. Sunweb also have two and Jumbo Visma have two. But it's all quite messy at the moment. Arkea-Samsic there for Greipel as well.

Michael Kwiatkowski drops back after a long pull as Luke Rowe takes the baton for Ineos.

It's all strung out as the road narrows and then weaves through a roundabout.

Riders being shelled out now that the teams of the sprinters have thrown down the hammer. They cross the Saone river and Ineos have come forward, too, to keep their GC men out of trouble.

Bora-Hansgrohe charge to the front. They've contributed nothing to any of the chase but now they pack their whole team forward in support of Peter Sagan.

Rossetto throws in the towel and Offredo soon follows. It's all over for the break and now it's show time.

Rossetto and Offredo still holding on - no doubt vying to be the day's most competitive rider by staying out the longest. Just 10 seconds now...

Once again, today's finish in Chalon comes sixty years after Britain's Brian Robinson soloed to glory in the same Burgundy town by the fourth-largest winning margin in Tour history. I spoke to the 88-year-old cycling legend ahead of today's stage about that day...
