Iain Marshall: Froome now doing a duathlon!

Gregg Coull: FROOME IS RUNNING UP VENTOUX!!!! WHAT AM I SEEING!!!

Jess Parsons: Oh my god. @chrisfroome, the yellow jersey just RAN up Mont Ventoux.....what is this finish?!?!?

We're watching a replay.

The motorbike in front of Richie Porte brakes - we can't see why - and Porte goes into the back of it.

Bauke Mollema and Chris Froome crash into Porte. They all go down.

You can only assume the motorbike has stopped because of the crowd...

Unbelievable. 

Unbelievable.

Have I said unbelievable?

Froome has lost a minute and a half to Bauke Mollema.

Will it stand?

Mollema meanwhile has a bike and finishes. Fabio Aru finishes too.

Froome has given up on the bike he was given - he couldn't clip in.

This is absolutely bonkers.

Froome has no bike after that crash and is legging it towards the finish line. Finally he's given a bike.

One of the three of them has hit a motorbike and they've fallen.

Chris Froome is running up the hill!

There's a crash involving Froome, Mollema and Porte!

Froome and Porte hold on to Mollema and now Porte takes the initiative.

Now, back to the yellow jersey.

Chris Froome, Richie Porte and Bauke Mollema are out of sight from Nairo Quintana.

Mollema is just 56secs off Frome in the GC and he's on the attack.

Navarro can't keep up.

It's De Gendt and Pauwels pumping to the finish line - De Gendt will take it. Brilliant stuff.

At the front of race, Daniel Navarro is bavk with Thomas de Gendt and Serge Pauwels. It's all going on.

250m left for these three.

And now Bauke Mollema goes past Nairo Quintana and has caught Chris Froome and Richie Porte.

Quintana is looking up the road at Richie Porte and Chris Froome. A nightmare for the Colombian, who was supposed to be the one attacking today.

Chris Froome's attack is a good one. Nairo Quintana and Richie Porte are the only men to go with him.

But wait, Quintana can't keep up!

Nairo Quintana is an absolute tease.

He looks like he's off again, but Richie Porte is alive to it.

And here goes Chris Froome!

Thomas de Gendt is fading after that burst to lead the stage and Sege Pauwels spots the weakness and looks to go past the Belgian. They stay alongside each other.

Dan Martin seemed to be off the yellow jersey group but is gritting his teeth and eyeing a return to the pack.

More attacks from the yellow jersey group.

Joaquim Rodriguez, who will retire this year, has a go off the front - Alejandro Valverde is the man to catch him, before Wout Poels casually goes past both of them to control the pace again.

This is granite riding from Poels.

Michael Ivory: Think Froome owes Pouls a beer! After next Sunday of course....
