And just as I typed that... race director Christian Prudhomme has made the call to can the summit finish at Mont Ventoux.

Stage 12 will go to Chalet Reynard, which is still on the climb, but around 500m lower in altitude at 1,435m and will make the stage 6km shorter.

And that really is me done.

While intrepid 5 live presenter OJ Borg goes off in search of riders to talk to, it's time for me to head off.

Thanks, as always for your company - some cracking photos - be sure to join us tomorrow for stage 12. We definitely know that it is starting in Montpellier. Where it will finish, is in the hands of the weather gods.

The report, which will contain more reaction, is live and we'll be back at 12:00 BST for Bastille Day fun.

So, that was stage 11 and on to stage 12 we go.

Here's what Geraint Thomas had to say in his BBC Sport stage-by-stage guide:

"t's Bastille Day and that means one thing: a lot of fighting among the French riders to get in the break. Not that the break will stay away because the general classification riders will come to the fore on the legendary ascent of Mont Ventoux."

I've been hanging on a bit to see if there is any news about the ascent of Ventoux tomorrow but so far I've heard nothing. 

It will be a huge shame if the summit finish is canned but completely understandable with 100km/h winds forecast. Racing to Chalet Reynard is the plan B...

1. Peter Sagan (Svk/Tinkoff) 3hrs 26mins 23secs 

2. Chris Froome (GB/Team Sky) Same time

3. Maciej Bodnar (Pol/Tinkoff) 

4. Alexander Kristoff (Nor/Katusha) +4secs

5. Christophe Laporte (Fra/Cofidis)

It turns out that for all Chris Froome's effort, he picked up just 12 seconds on Nairo Quintana - six clear and six more for finishing second - could they prove vital though?

He is top of the podium right now, getting another yellow jersey.

Here's his assessment of the finish, without the naughty word. "<bleep> happens. At least I didn't get beaten, that's the positive I can take from it. My rear mech stopped working and there was no way to get back on."

And on Chris Froome attacking. "Fair play. It's quite nice for the race to see the green and yellow jersey up the road."

Peter Sagan has gone 90 points clear in the race for the green jersey. He now has 309 points with Mark Cavendish second on 219. 

It looks like a fifth successive victory in that classification for the Slovak.

The official results are in and Chris Froome has extended his lead over fellow Briton and second-placed Adam Yates to 28 seconds with Ireland's Dan Martin still in third, 31 seconds adrift.

Nairo Quintana of Colombia is a further four seconds back.

A few words from our winner Peter Sagan: "It was something crazy what happened. Froomey and Geraint came with us and I said 'We are too strong they are never going to catch us'. So we pulled hard and it happened. There was a crazy wind and it  was not planning to go in break with green and yellow and Geraint and Bodnar. You cannot plan that it just happens."

Geraint Thomas on ITV4: "I was surprised. Sagan was just motoring. When they went, Froome responded and I just went full gas. When we got a gap and heard it was 15-20 seconds, we had to commit. Boy was that hard."

The only downside for Geraint today is that he didn't pick Peter Sagan for the stage win in his stage-by-stage guide!

I think Rob Hayles summed that up perfectly. A bonkers finish to a crazy stage. 

A sprint between the green and yellow jersey. On a flat stage.

They both got exactly what they wanted though. A perfect day all round. Apart for Mark Cavendish.

Rob Hayles on BBC Radio 5 live Sports Extra: "That was absolutely bonkers. I'm wondering if those 12 seconds are going to be worth it given the amount of effort put in by Froome and Thomas. But what an incredible show."

Chris Froome briefly jumped out of his saddle but I think that was more to put as many seconds as he could into Nairo Quintana.

Peter Sagan celebrates as he crosses the line to retain the green jersey. Froome looked over his shoulder as he took second with Maciej Bodnar in third.

The peloton was around a dozen seconds adrift and it will be interesting to see, with time bonuses, how much time Froome has picked up.

PETER SAGAN WINS STAGE 11

Into the final kilo and the leaders are just 14 seconds clear. Geraint Thomas burying himself on the front. He steps aside and Chris Froome goes full gas. He's looking at Peter Sagan.

Peter Sagan, Geraint Thomas, Chris Froome and Maciej Bodnar are working well together and maintaining a 20-second advantage as they head into the final 2km.

Sagan is clearly the quickest rider of the four and will take the stage win if they can hang on.

"If I was Chris Froome I would say to Sagan you commit to this and give it everything then we will not contest the stage win," says Hayles.
