Simon Clarke is being followed by a huge mass of riders, all flying down the wide avenue of the Champs Elysees and setting up their own lead-out trains. 3km left.
Garmin Sharp are trying to get men up there too, as an Orica Greenedge rider - Simon Clarke - flies off the front of the peloton. He leads by seven seconds with 4.5km to go.
The sprinters' teams are fighting for position now, with lead-out trains for Norway's Alexander Kristoff (Katusha), Germany's Marcel Kittel (Giant), Slovakia's Peter Sagan (Cannondale), Germany's Andre Greipel (Lotto) and Mark Renshaw (OPQS) jostling for the best line. 6km left.
The sprinters are licking their lips and flexing their hips as they take the bell for the final lap. 7km to go of the 2014 Tour de France and Richie Porte has just been caught. The peloton are back together.
Richie Porte is still pedalling hard but he must know now that he will be caught. The pack are only four or five seconds behind him now and it is inevitable that he will be hoovered up.

"There's a few spots of rain, it's starting to spit. Let's hope they all stay upright. This could be an epic end to what has been a pretty dramatic Tour de France."
Omega Pharma QuickStep are up near the front of the chasing pack - Tony Martin is doing the legwork as they try to set up their surviving sprinter Mark Renshaw to challenge the fast men I spoke about earlier.
Ji Cheng, the lanterne rouge, is being lapped! He is still soldiering on mind you.
Richie Porte flashes past him and now leads the pack by 12 seconds with 11.6km left. Rain is falling in Paris.
Poor old Tony Martin has had to change his bike again but he is back in the peloton and avoids a lonely ride round Paris for the next 15 minutes or so.
Richie Porte kicks again! The other two escapees are history, but he is clear on his own.
Here we go then. Two laps to go and Australia's Richie Porte (Team Sky), Denmark's Michael Morkov (Tinkoff) and Colombia's Jose Serpa (lampre) are being reeled in. With 14km to go, they are just nine seconds ahead.

"It's been a bit unfortunate, with Richie Porte ill after Chris Froome went home and Geraint Thomas has not looked 100%. I think there will be a big think about what's gone right and wrong. They will learn from their misfortune and improve.
"Team Sky won the Tour de France back to back but at some point, taking a bit of a setback is not a bad thing as you move forward."
Another mechanical. This time Tony Martin has lost his chain. He won't mind too much.
The three escapees are now just 15 seconds clear, with 15km to go.

These are the men to watch out for in the final few kilometres of the 2014 Tour de France: Alexander Kristoff, Marcel Kittel, Peter Sagan and Andre Greipel are the sprinters eyeing the most prestigious stage victory of all.
The Orica Greenedge team have two men clear of the peloton, trying to bridge the gap to the escapees.
Richie Porte is still driving that breakaway group away, and has opened up a gap of 22 seconds with 20km to go. Back in the pack, overall leader Vincenzo Nibali is staying out of trouble.
Alexander Kristoff is back in the peloton and further up the road, that front four has become a front three - Richie Porte, Denmark's Michael Morkov (Tinkoff), and Colombia's Jose Serpa (Lampre). With 22.5km to go, their lead is 13 seconds.
Our four men in front have a lead of 16 seconds with 27km to go. They are Team Sky's Richie Porte, and Morkov (Tinkoff), Serpa (Lampre) and Fonseca (Bretagne).

"It's cloudy at the moment in Paris, and the excitement is building. Thankfully, there's been no rain whatsoever."
Problems for Alexander Kristoff too. He is one of the sprinters in contention to win this stage but he has ground to make up on the rest of the pack after suffering from a puncture.
Helpfully, he has a problem with his saddle too, and gets a convenient 'tow' from the team car as that is sorted out...
