So quick. Oh crikey, they come out of a right-hander and road furniture almost causes havoc.
Everyone avoids it.
Lotto Soudal look well placed for their man Andre Greipel.

Today's finish will more than likely see every one of the sprinters who have shown their face doing the same. The chances are Cavendish could very well get his 29th stage win. There will be an uphill drag race to the line and I feel the winner will be the one who leaves it to the last minute to jump.
5km to go
Now Tinkoff take the central position and Lotto Soudal move into the gap on the left.
It's three-pronged with Team Sky out right.
6.3km to go
Team Sky take up a position on the right of the peloton. Tinkoff, in their fluorescent yellow, have occupied the left flank.
7km to go
Alexis Gougeard, looking worse for wear, falls off the breakaway and disappears down the side of the peloton.
Two men remain in the first group.... they don't any more. They've been caught.

I recommend you click the audio button at the top of this page to listen to commentary of the run-in.
Here are our team's predictions for the winner.
Rob Hatch:Â Bryan Coquard
Rob Hayles: Bryan Coquard - the frustration felt by the Frenchman in coming third could very well spur him on.
OJ Borg: Cavendish to win - he rides on emotion and confidence and I think that will give him the extra 5 per cent todayÂ
9.8km to go
The peloton are putting their foot down now - expect riders to start dropping off the back.
The gap is down to 15 seconds.
OJ Borg has caught up with Team Sky boss Dave Brailsford.

13.3km to go
Jesus Herrada has taken up the march at the front of the peloton for Movistar and their man Nairo Quintana.
Also, Alejandro Valverde, while not a pure sprinter, might fancy a go at this up-hill finish - so Movistar are keeping things ticking over.

It's the first real warm day of this year's Tour and it's only going to get warmer now.
It all adds up and if you get your hydration wrong today you can pay for it tomorrow.
They're not huge climbs tomorrow but they keep coming at you.
18km to go
Still three men in the breakaway -Â Irizar, Naeser, Schillinger.Â
They have a mass of bodies hunting them down and the gap is at 25 seconds.

It’s another sprint stage so a busy day for Tinkoff because they have race leader Peter Sagan in their team. It will all be about getting your timing right for the sprint finish. We’ve got a rise of 25m in the final 500m but the sprinters will all be there.

William George:Â I like to mimic Cav on my rides, whenever I get to a hill I fall to the back...
Stephen Louch: Cav shows dedication and a willingness to win that few in other sports put in. Sadly lack of appreciation for "riding a bike"Â

Katusha's Michael Morkov is drifting away from the back of the peloton. He's no doubt sore following his crash on Sunday.

This is going to be a a big, big sprint.
There's talk that this could be Peter Sagan's last day in yellow because of the stages coming up but we really don't know.
With 30km to go, and the peloton 40 seconds behind the breakaway, it's time to start talking about the sprint finish.
Who do we reckon will be on this stage later?
