Defiant zombie: Laura Muir risked it for a biscuit and ended up with a rich tea :(

Padraig Lennon: She went for gold and gave it everything, fair play.

Rick: Brave attempt by Laura Muir but looked to be running through treacle in the final 300m

So near yet so far for Robbie Grabarz after he missed out on a medal by finishing fourth in the high jump final.

"I'm gutted," he says. "Fourth is a punch in the face."

Great Britain's Laura Muir after finishing seventh: "I went for the win, it's not every day you find yourself  in an Olympic final. I was in great shape but the last 150m was not quite in me. I gave everything and I'm proud with how I ran. 

"I expected it to be slow start and then for Kipyegon and Dibaba to come round. I expected to have to react, I followed them round but I couldn't hold on. 

"It's my first Olympics, I gave it everything."

I thought Laura Muir ran exceptionally well. She did try to win it. Sometimes if you go for gold you come away with nothing at all.

Poor Laura Muir. She went with it but these two - Kipyegon and Dibaba - are so good. They make you go so hard. Muir's chance of a medal went with those two. She went for gold but gave up her chance of hanging around and picking up a medal.

Faith Chepngetich Kipyegon powers through and is streaking away at the front. It's not good news for Laura Muir, she's pushed too early and is dropping back...

The pace is shifting up a gear now. Genzebe Dibaba moves into the lead but Laura Muir is on a charge, third at the start of the final lap...

Two laps to go and Laura Weightman moves to the front as Laura Muir makes her move from the back on the outside.

It is a field of champions. This is all about tactics. Somebody, maybe Laura Muir, has something in her mind about going out there and being brave with two laps to go.

Away they go and it is a gentle jog to start with. Laura Weightman is currently in third, Laura Muir is biding her time at the back...

On the blocks and ready go. Will we have another British medal winner in a few minutes time...?

Laura Muir will need to decide whether she gambles everything and goes to win the race from the start, or go for a medal which she know she can do, and try to win it from there. To lead from gun to tape is pretty much impossible in a 1500m race.

American Erik Kynard sported some eye-catching socks worthy of an Olympic champion but unfortunately he had to settle for sixth place in the high jump.

Right then, women's 1500m final time. Great Britain's Laura Muir is in this. The Scot, a student of veterinary medicine, is off for a two-week placement at a dog rescue centre after Rio. A medal would be a pretty nice way to sign off.

Also in this is Muir's team-mate Laura Weightman. She finished 11th in the final of the same event at London 2012.

Matthew Birch: I really think, to a normal bloke, that high jump is the single most ridiculous Olympic sport. How do they do this?

Richard Cohen: Can something technically be a 'semi-final' when there are three of them? Doesn't that make it a 'third-final'?

GB's Dina Asher-Smith has scraped into the 200m final after a fourth place finish in the semi.

American Tori Bowie wins the third semi-final in 22.13, with Trinidad and Tobago's Michelle-Lee Ahye just behind her. 

But what about third place?! A nervous wait... Jamaica's Simone Facey races a season best time of 22.57. It's not enough! GB's Dina Asher-Smith scraps into the final as a fastest loser!
