Women's 1500m final
Caster Semenya was nowhere with 200m to go, maybe sixth or seventh, but finished so well.
WHAT a finish from Jenny Simpson too, she ghosted in on the inside in the last 50m or so to take silver. Canny.

Laura Muir should be disappointed and she will be disappointed. She's a great athlete. She will win a global medal.
Women's 1500m final
That's why the 1500m is such a good event to watch. The winning time of 4:02:59 has been bettered by nine athletes in the field this year alone, but it's not always about times. Laura Muir tried to control the race from the front all the way.

Laura Muir was so close. When you have the medal snatched away it's gut-wrenching. Gut-wrenching.
Darren Campbell
Former British sprinter on BBC Radio 5 live
When that lactic comes, how difficult is it, what can you do? Wow.
Women's 1500m final
Laura Muir fourth and Laura Weightman sixth. A brilliant effort, if not quite good enough for a medal.

Every one of the athletes that should have been on the podium ran someone else's race.
Image source, PAMuir wound it up and she just ran out of legs in those final 20 minutes. The master tactician of Jenny Simpson of the USA again gets on the podium.
Two Brits in the top six is phenomenal but Laura Muir in that fourth position, that is heartbreak, absolute heartbreak. The world record holder finished 12th. That's where we are at with this event.
Women's 1500m final
Faith Kipyegon kicked and went for gold from a way out and was able to hang on, Laura Muir responded and looked set for at least a bronze all the way, but Caster Semenya, finishing strongly, pipped her to bronze.
Jenny Simpson was second. Great run.

Laura Muir in the dying strides is relegated to fourth and suddenly it's like everything has left the stadium.

We need another gear from Laura Muir...
Women's 1500m final
Laura Muir in third, there's another kick. This is fast from Sifan Hassan...
Women's 1500m final
A 71-second second lap. Playing into Caster Semenya's hands? Now the move comes. Sifan Hassan kicks...
There's the bell. Laura Muir maybe third with a lap to go.
Allison Curbishley
BBC athletics expert on Radio 5 live
Not ridiculously quick early on. 65 second for lap one, that's about 4 minutes and three second pace. I think Laura Muir will try to turn the screw...
Women's 1500m final
Controlled pace so far, it's starting to slow down though...
Women's 1500m final
Faith Kipyegon moves to the shoulder of Laura Muir. They are all packed in, this is going to be all about the kick.
Women's 1500m final
Laura Muir is at the front but it's not crazily quick. A 65-second lap.
