Beth Potter starts the running ahead in front after USA's Taylor Knibb had a bit of a sloppy transition. But the three athletes keep exchanging the lead.

This is anyone's race now.

This is getting tense.

USA's Taylor Knibb and Germany's Laura Lindemann surge ahead of Beth Potter - but Potter responds and the three athletes are pretty much level as they transition to the final running leg.

This is a great start to Beth Potter's final relay leg.

Paris is looking an absolute picture in the early morning sunshine, with the streets packed full of spectators looking to catch a glimpse of the action.

They are witnessing an absolute thriller too as Team GB's Beth Potter exits the water and transitions to the bike leg with a lead of seven seconds from Germany's Laura Lindemann, with USA's Taylor Knibb 18 seconds back in third.

Gold medallist Alex Yee has turned into the Team GB hype man after doing the first leg.

He's down in front of me on Pont Alexandre III at the finish line, triathlon suit half down, screaming for his team-mates.

Can world champion and bronze medallist Beth Potter finish it off to earn a medal?

What an incredible final relay leg from Sam Dickinson, he has made the most of having fresh legs.

Stunning finish from Sam Dickinson.

He hands over to Beth Potter, women's individual bronze medallist, with a steady lead for the final leg.

Both Dickinson and Luehrs collapse to the ground in exhaustion at the end of their run. They both gave it everything.

The chasing pack have pulled back about four or five seconds on the leaders, but what a run this has been for Sam Dickinson. He's had so much pressure on his shoulders, but he has absolutely delivered. He will want to power home and give Beth Potter the best chance possible.

Hello! Sam Dickinson has opened up a nice gap of a couple of seconds, kicking ahead of Lasse Luehrs who is grimacing.

Sam Dickinson is never going to have better opportunity of being an Olympic champion! He has the German, Luehrs sitting on his shoulder, but it's a real opportunity.

This has become a really exciting, intense race and I don't think we expected otherwise. This run leg is now crucial. Sam Dickinson will give us the best chance possible when he hands over to Beth Potter, but the chasing pack are coming, you can't take your eyes off. It is riveting.

Oh, this is going to be so tight - excellent transition for Sam Dickinson, but what lead can he give Beth Potter to work with in the final leg?

Billy: Triathlons are nuts, go on Team GB!

Dickinson and Luehrs were pretty much side-by-side the whole way round that cycling course. They could've been having a lovely chat as they went.

We've got two races going on now, given the gap between these two and the chasers - a scrap for gold and a scrap for bronze.

Sam Dickinson has a rapid transition from bike to run, whips on his trainers and gets a good start on the 1.8km leg.

Sam Dickinson will be happy to see that the chasers are behind him. He and Lasse Luehrs are a good way ahead now.

We've got a great contest on our hands here.

Sam Dickinson and Lasse Luehrs are neck and neck as they change over on to the bikes. GB are the defending Olympic champions, and Germany the world champions so this should be a great finale.

Switzerland are in third place. France, who were up there with the favourites, are still struggling to recover from Pierre le Corre's devastating fall on the bike in the first leg.

Sam Dickinson is leading and is having a brilliant swim here.

What a cracking run from Lisa Tertsch of Germany! Georgia Taylor-Brown was 20 seconds clear at the start of the final leg.

Sam Dickinson then takes an early lead in the swim and is out of the water first, but Germany's Lasse Luehrs is right on his heels.

Ooft. What a run from Lisa Tertsch to overhaul Georgia Taylor-Brown on the line.

Its only a lead of one second, though, for Germany…
