The post mortem on British success will continue - it was ever thus.

Join us tomorrow night when there are five gold medals up for grabs.

See you there!

I remember the days when Britain won four or five medals. The Olympics in 2004, Kelly Holmes was the only one to leave with medals at the track. The pressure was on us the relay team to win one. If medals are not won, the funding is cut. All this stuff the young athletes have been given will go.

So then you are back to the place where you have to graft again. You may have to have a job and train.

The reality is that Mo Farah has the only medal. He is retiring from the track. What are we pinning our hopes on?

Some guys have made finals. That is good for next time. But we have got something wrong.

Brendan Foster has been on here. We are letting him walk away and not tapping into all the experience he has... wow!

Laura Weightman was really low after Rio. She needed a lot of help. To add to it she was taken off funding. What she did was find a really good psychologist at Leeds Uni. She is a new athlete, a better athlete.

Great Britain won seven medals at the last World Championship, with four golds.

Two for Mo Farah, Greg Rutherford in the long jump and Jessica Ennis-Hill in the heptathlon.

If you look across the events to come, you couldn't pin your hope on anything other than the relay teams. However you look at it, it's troubling for this sport.

A race plan with a second lap of 71 seconds isn't a brilliant race plan in my view. It can play into the strength of the sprinters. Her running in the last 400m was strong, she went a bit fast on the final bend which took a bit out of her. She was unlucky, gave it all she had but I didn't think the race plan was brilliant.

Kenya's Faith Kipyegon won the women's 1500m at the World Championships as Britain's Laura Muir was edged into fourth place at London Stadium.

The Scot, 24, was overtaken by South Africa's Caster Semenya on the line for bronze, with Jennifer Simpson of the US taking silver.

Caster Semenya, that is the hardest we have ever seen her work. She threw herself over the line, you could see the exhaustion on her face. I'm not sure what that will do for her and the 800m.

Briton Laura Muir, who finished fourth in the 1500m, talking to BBC Sport: "It's fourth. I gave it everything I could. I tied up in the last 15 yards. I gave it everything, considering the disruption I've had this year. I knew it was close. It happened so late in the race. I couldn't react, but I wouldn't have been able to because I was so tired.

"I executed the race plan like I wanted to do. I was really happy how I ran the race.

"I'm making steps. I was fifth at the last Worlds and fourth this time - hopefully I'll make another step.

"I'm pretty sure the 5,000m is still on the cards this week. I'm inexperienced in the 5k so I don't know if I'll get a medal. I'll see how I feel after today."

Faith Kipyegon won the Olympics with another well-judged race last year, with Sifan Hassan fifth again.

Sifan Hassan looked nailed on for at least silver with 30m to go and faded fast, Simpson and Semenya timed their kicks to perfection.

Laura Muir says in her BBC interview that she ran the exact race she planned to, taking it out hard and easing off a touch in the second lap. She did what she wanted - she just ran out of gas in the last few metres.

Matthew Hufford: Laura Muir was so unlucky tonight , this World Championship is not going the way the GB team would of liked

Gareth Hancock: Gutted for Laura Muir there. So close to a medal.

Michael Bennett-Lee:@lauramuiruns, external has more heart and guts than anyone I have ever seen you are wonderful

Laura Weightman speaks to BBC Sport: "I just wanted to prove I can mix it with the world's best but I'm also still disappointed. I was a bit boxed in. To finish sixth, I think it's given me huge relief, to think I can be quicker and be more competitive in these races."

Regarding Muir's tactics, it's so hard when you're in that situation and racing - you're the only one who can make those decisions. It nearly paid off.
