Things in my life don't usually go to plan, nothing had gone wrong so I was wondering what was going to go wrong and I got across the line, looked at the time and honestly can't believe it. I'm lost for words."

World Athletics Championships 2017: GB women claim silver in 4x400m final as USA take gold
Last summer, Zoey Clark, Laviai Nielsen, Eilidh Doyle and Emily Diamond took silver for Great Britain behind a serene American quartet at the World Championships.
In Amsterdam 2016, Anyika Onuora and Seren Bundy-Davies joined Doyle and Diamond in Great Britain's European gold winning team.
The kaleidoscope has turned once more and it is Clark, Doyle, Onuora and Amy Allcock who line up for this final. Nielsen, having gutted herself for fourth in the individual final less than two hours ago, is out of contention.
Italy were the one team to qualify quicker, but Britain's favourite status probably remains.

You can depend on Martyn Rooney in the relay. It was a great effort by that team and Dwayne Cowan too, to get the baton all the way across the track to Matthew Hudson-Smith in lane six.
Long jump
And it could have been more.
Just five centimetres separated gold from bronze in the pit.

Martyn Rooney could see what was happening in front of him and that sort of gives you a little bit more energy. The Spaniard was absolutely spent.

That was an impressive effort on the anchor leg from Martyn Rooney to take Britain to silver but the poor Spaniard could not move his legs.

What a race.
We knew Belgium would be very dangerous - they have a lot of talent in their team and they proved it today.
4x400m relay
And Martyn Rooney follows suit!
Poor Bruno Hortelano of Spain hit the wall in the final 50m. He looked like he was cramping, Either that or dragging an invisible shackle.
Silver for Great Britain.

Spain's Bruno Hortalano ties up suddenly and dramatically and Jonathan Borlee motors past to take gold!

A messy changeover. Matt Hudson-Smith the individual champion take it on and runs hard.
He hands to Martyn Rooney. Rooney has Spain and Belgium to overhaul. It is a massive ask...

The class of 2018 will have to go some to beat Jamie Baulch, Iwan Thomas, Mark Richardson and Roger Black.
Their silver-medal winning time at Atlanta 1996 still stands as the European record.

Great Britain have experience but the Belgians and French are going to be tough. Matt Hudson-Smith is confident after his gold medal last night and he should set up Martyn Rooney maybe in the lead. It should be a good race.
Men's 4x400m relay
Image source, Getty ImagesGreat Britain came third in last summer's World Championship with a quartet that comprised Matthew Hudson-Smith, Rabah Yousif, Dwayne Cowan and Martyn Rooney.
All four are back in harness tonight after 21-year-old Cameron Chalmers sat in for Hudson-Smith in the qualifying round.
The tactic paid off with Britain qualifying fastest and the rest helping Hudson-Smith to the individual 400m title.
France look the main threat, although a Belgium team defending their title from 2016 and packed with Borlee brothers - Jonathan, Kevin and Dylan all running - might get involved as well.
