Johannes Hoesflot Klaebo adjusts his gloves, comes round the corner and attacks on the final climb! He's exploded into life!

Martin Loewstroem Nyenget can't respond.

The second Swiss sled, piloted by Cedric Follador was fourth after heat one, but he loses time on Adam Ammour's German quartet and drops down to fourth overall with three to go and will probably fall further.

Britain are up next.

They're side by side!

Just over 1000m to go.

Thumbs up for a sixth gold of the Games for Johannes Hoesflot Klaebo. Thumbs down for Martin Loewstroem Nyenget, who still has his nose in front.

The German sled piloted by Adam Ammour throws down the gauntlet - he is 0.12secs clear after a better second run and that puts the pressure on the next two sleds - including Britain.

Two kilometres to go and Johannes Hoesflot Klaebo is still happy to sit in Martin Loewstroem's Nyenget's shadow.

Into the final three kilometres and it's a two-way battle for gold.

Johannes Hoesflot Klaebo is right behind Martin Loewstroem Nyenget.

The first of the two Swiss sleds in the top six keep their hopes of a medal alive as they finish 0.07 clear of the field.

We will see the British sled shortly.

What can Italy do?

It isn't the ideal start but they find speed down the track and they complete 0.11 seconds ahead of the Koreans - remember this is the combined time from both runs!

The home fans like that.

Emil Iversen has been distanced by Johannes Hoesflot Klaebo and Martin Loewstroem Nyenget.

Comedian and TV presenter Romesh Ranganathan has wished good luck to Team GB bobsleigh pilot Brad Hall - who he used to teach in his former career as a teacher.

Ranganathan taught Hall, now 35, maths at Hazelwick School in Crawley.

Ranganathan joked: "One of my fondest memories was Brad saying to me: 'Mr Ranganathan, genuinely, you are a hero and a role model, and I am going to compete for Team GB as a direct result of your influence'."

Jane Hall said her stepson took Ranganathan down a bobsleigh run in Switzerland last summer as a "pay back" for all the homework he had given him.

Hall will be in action shortly in the second of four heats with his GB sled in third after the first run.
