Hello and welcome to live coverage of stage 20 of the Tour de France - the all-important 22.5km individual time trial in Marseille, where the destiny of the yellow jersey will finally be decided...

The top ten after today's stage - with Bardet holding onto his place on the podium by one second, Yates securing the white jersey and Contador moving about Barguil and into ninth place.

So, it's a Polish-themed podium today as Maciej Bodnar takes the win by 1 second over compatriot Michal Kwiatkowski, with Chris Froome in third at six seconds.

Confirmation that Chris Froome is now 54 seconds ahead of Rigo Uran, with Romain Bardet staying on the podium by just one second! The Frenchman is 2:20 down, with Mikel Landa just one second further back.

Chris Froome was six seconds down on Bodnar, so it's just third place for the Team Sky man - who has all but won a fourth Tour de France.

Bardet comes home - just seconds ahead of Froome!

These long straights have not been kind to Bardet... he has Froome breathing down his neck!

Froome may well catch Bardet before they come into the stadium... that would be the ultimate humiliation!

OH NO! Uran slams into the barriers after overcooking one of the final bends! He manages to stay up on his bike, but that was a heart-in-mouth moment. He finishes 31 seconds down on Bodnar - and it should still be enough for second on GC. Well saved, Rigo!

Here's Mikel Landa - and he's 51 seconds down on Bodnar at the finish. Time will tell if it's enough for him to push Bardet off the podium.

Fabio Aru comes home 1'16" down on Bodnar's target time...

Froome could well catch Bardet at this rate - he crosses the summit not far behind the Frenchman... and three seconds slower than Bodnar.

Bardet is really suffering on this climb... he's in and out of the saddle, and pedalling squares. He could move below Landa on GC at this rate. He's 1'17" down.

Bardet is onto the climb now - and he skidded on the tight corner ahead of it. Uran is piling on the pressure - he went over the top 21 seconds down on Kwiatkowski.

Landa was 26 down at the first check and 33 down at the second check - so he could knock Bardet off the podium, but it's unlikely.

Froome is on course: he's only two seconds down on Kwiatkowski at the first check.

And Bardet is 45 seconds down, so it looks like the Colombian will move above the Frenchman today...

Uran is 26 seconds down at the first check...

Alberto Contador fades over the final quarter to come home in fifth place, 21 seconds down on Bodnar at the Stade Velodrome.

Fabio Aru is 38 seconds down at the first check... he's on the cobbled section now and has the climb coming right up.

Contador is on a storming run: he's equal with Kwiaktowski over the climb and is well poised to beat Bodnar's time at the finish.
