We have seen some racing in these events. I have never seen two events back to back with ties for medals.

This is absolutely phenomenal, this is bobsleigh at its best. After four miles of racing, you can't separate them.

Extraordinary! South Korea's crew led by Won Yunjong weren't expected to be in the mixer for a medal, but set off in the silver medal position.

Oh my... this is tight. Can Won edge ahead of Nico Walther... no! They're tied for silver. Absolutely zilch between the two crews.

Nico Walther is one of the best pilots on the circuit. You can see what it means to Kevin Kuske.

This is Walther's first Olympic medal and Kuske's sixth, but every one of them means so much to each athlete.

First up is Germany's Nico Walther. He won bronze at the world championships, can he match that at the Olympics? Yes!

Walther secures a medal with a run of 49.58, also clinching a sixth Olympic medal for his team-mate Kevin Kuske.

Justin Kripps needs to be spot on - but he ain't. The Canadian makes a couple of boo boos and slips to sixth.

Down to the final three...

Rico Peter is one of the fastest pilots on the circuit, when he gets it right.

That was a great run, one of the best lines down the straight.

The Canadians will need to be spot on.

Barely anything between Melbardis and the next pilot at the top of the track - Switzerland's Rico Peter.

It's a straight shootout and Peter's comes out slinging. He's ahead by 0.06 seconds.

Latvia's Oskars Melbardis, like the most of the others, find their fourth run the slowest, but still move into top spot with a total time of 3:16.65.

Down to the final five...

You don't normally see mistakes from the Germans, they're normally ice cool at the top of the track.

It just shows how everybody is under pressure.

The German programme will have three sleds in the top eight, but Johannes Lochner will be unhappy with that.

He's been under pressure at his first Olympic Games.

Austria's Ben Maier improves to seventh place with a total time of 3:16.90, pushing Germany's Johannes Lochner into eighth.

Lochner was thought to be a medal contender going into the Games as well.

Britain's Lamin Deen and his crew are set for 18th place after failing to go out in style with their final run.

Watch it here:

Back to the sport... we're about halfway through the final run of the men's four-man bobsleigh.

Zut alors! France's crew, piloted by Loic Costerg, almost provide us with our first crash, jumping into the side of the track, threatening to wobble over before settling down to safety.

The International Olympic Committee members have spoken...

Russia's Olympic ban will be lifted if there are no further doping violations from their athletes at Pyeongchang 2018, says the IOC.

However, the IOC says Russian athletes will not be allowed to parade under their own flag at the closing ceremony.

Russia was banned because of state-sponsored doping at Sochi 2014.

A team of 168 competed in South Korea as neutral Olympic athletes from Russia but two failed doping tests.

Lamin Deen's sled is one of the fastest on the circuit, so there is nothing wrong with the equipment.

It's good for Brad to have bragging rights as the number one GB pilot at these Games.

There have been lots and lots of errors from both sleds and that has been the story of the Games for GB.

And that disappointing run by Deen means that Hall and his team will finish above their British team-mates in the overall result.

Hall's team have a cumulative time of 3:18.26, 0.03 ahead of Deen's.

Can Lamin Deen go out with a blaze of glory in what is going to be his final Olympics run? No.

The British team make a woeful start, and struggle from then on. A time of 49.74 seconds leaves them propping up the field in this fourth and final run.

For Brad Hall to be top 18 at his first Olympics, you'd expect that, but that's not where he wants to be.

In terms of his development, his has been a massive learning experience for him.

This team have pushed well together but as a whole, he should be relatively happy with how he's performed at these Games, looking ahead to Beijing 2022.

Two British teams are still out there, although they are well out of the running. Brad Hall and his crew start down in 18th and they go just ahead of Lamin Deen's team.

Hall's lot clock up a time of 49.69 seconds.
