Seven Nation Army booming out now, fabulous atmosphere despite the relatively small crowd.

Here comes Renaud Lavillenie. Attempt two at 6.03m. 

Here comes Thiago Braz da Silva. For a chance of gold...

6.03m - he doesn't reach the bar. 

Renaud Lavillenie clears 6.03m! - But no! He lands on it on the way back down and knocks it off.

He will still win gold. Unless his Brazilian foe can clear this...

Renaud Lavillenie is the defending champion and the huge favourite. He's cleared every bar first time. But he doesn't look hugely confident. Doubts?

The bar goes to 6.03m

Olympic 800m champion David Rudisha: "My training was great and I have been having really good sessions since I was injured.

"I have had no doubts about my form - I never doubted myself.

"To win my second gold is a great moment for me."

Thiago Braz da Silva has PASSED at 5.98m. He can't win gold by levelling with the Frenchman anyway. This way he gets three goes at the next height. I like the cut of his job.

Wonderful noise as Da Silva battles for pole vault gold. All his rivals have been booed, but if this makes sense, it's all rather marvellous.

Top class! You can't argue with that as Renaud Lavillenie clears 5.98m at the first attempt.

Is that gold?

Deuce Carter wins the unique 110m hurdles re-run in 13.50 seconds and qualifies for the semi-final as a fastest loser.

Sam Kendricks gave the bar an almighty wobble at 5.93m, it nearly stayed on. He is out - but he has a bronze medal for his luggage. 

Brazil are guaranteed a medal in the pole vault.

The three men who will win medals - colours TBC - are Thiago Braz da Silva, Sam Kendricks of the United States, and Renaud Lavillenie of France. 

Thiago Braz da Silva has cleared 5.93m! He stays in the medal hunt. In the gold hunt!

The home crowd go nuts. 

USA's Sam Kendricks attacks 5.93m with real pace, so much speed on the runway. The first half of the jump is good, he's over the bar - but he clobbers it on the way down.

Second time lucky for Deuce. But not for Serbia's Milan Ristic, the previous slowest fastest loser, who - hokey-cokey style - was first in and then out.

Renaud Lavillenie has cleared 5.93m! He's the class act in this field. Easy. Miles over!

Brazilian Thiago Braz da Silva is in silver position...

Deuce Carter wins the re-run in 13.50 seconds.

Is that enough? Yes. He is through at the second attempt.

The re-run is on. Deuce Carter - who was unhappy in the rain a few hours ago - gets another chance in the play-off for the qualifiers. There are six in the field.

Ian Bradley: Not sure what the technical difficulty marks will be for that dive but congrats Miller, Olympic 400m champion.

Mike: What a race! Phenomenal. Miller has beaten a great in Felix.

Shahid Miah: Millerjust defined diving - dive for a Gold medal not for a penalty! Congrats.

Alastair Susans: Bolt has to dive through the line in the 200m. Them's the rules now.

I don't think Usain would need a dive, he's usually strides ahead of the field by that point...

Dive for the line!
