BBC Radio 5 LiveSonia McLaughlin has just asked Tiffany Porter whether her confidence was knocked by her failure in the world championships final last year.

"Maybe I got that one wrong," says Sonia...

Tiffany Porter's younger sister Cindy Ofili goes in the next semi. Can she get through?
Tiffany is watching from on high, pacing up and down. Her sister could knock her out here. Or they could both get through.
Or neither. Intense stuff...

Nia Ali wins it in 12.66 but there's drama just behind, Jasmine Camacho-Quinn was right in the mix for second or third and clatters the hurdle hard, bailing out.
She is in instant tears. It's a brutal event.

GB hurdler Tiffany Porter: "I didn't really plan for that to happen. I don't know what to say. I think I panicked, I need to relax. It is over now, I don't know if it will be good enough to get me to the final but we will just have to wait and see."

YES! I'm delighted you enjoyed that one. It's genuinely the first thing I think of whenever I see a javelin.

Steve Cram
BBC athletics commentator on BBC TVKenya's Ezekiel Kemboi has been disqualified from the men's steeplechase for putting one foot off the track during the race earlier today. He had won bronze, but that medal is now awarded to Mahiedine Mekhissi of France.
We are astonished at that decision, given the fact that Ezekiel Kemboi was so far ahead. It is one foot and that means he is now disqualified - it is a pretty harsh decision.

Brianna Rollins was the favourite, and the American wins it at a canter in 12.47. Top class.
Tiffany Porter is fourth in 12.82 and is almost certainly out.

Cindy Roleder - world silver medallist last year - is also in this semi. So Tiffany Porter will have to really go for it.
