Men's high jump final
This is remarkable.
No man has ever defended a world high jump title. Barshim spent 14 months out of the game after rupturing ligaments in his take-off ankle. The qualifying contest in Doha was only his fourth competition since returning from injury.
And he's now in medal contention...

This is a very fast race - Getnet Wale still at the front and so too is compatriot Lamecha Girma.
Zak Seddon still way, way back.
Girma leads them through 2km at in 5:22.95.

Maksim Nedasekau misses his first shot at 2.35m.
Mutaz Essa Barshim takes a second to compose himself, the crowd roaring behind him...
OH! Cleared it on the first go! My word!
Men's high jump final
Right then. Down to the last four in the men's high jump.
The bar's gone up to 2.35m. Russia's Mikhail Akimenko, Belarusian Maksim Nedasekau, hometown hero Mutaz Essa Barshim and Ilyal Vanyuk are going to leap it out for the medals.
Men's 3,000m steeplechase final
Beyo and Wale still at the front with Kipruto also up there at the 1,000m mark.
Men's 3,000m steeplechase final
Zak Seddon is one of two at the very back at the pack, and a gap is forming ahead of him.
Needs to push on here.
Men's 3,000m steeplechase final
The final is under way and it's immediately a sprint to the front.
Ethiopia's Chala Beyo and Getnet Wale lead in these early stages.
Men's 3,000m steeplechase final
The next final on the track is the men's 3,000m steeplechase final.
Zak Seddon is the first British male finalist in the event since 1993.
Kenya-born athletes have won every men’s steeplechase world title from 1991 onwards, but that could come under threat because Morocco’s 2017 silver medallist Soufiane El Bakkali came into Doha as this year’s world leader, while teenager Getnet Wale of Ethiopia won the Diamond Trophy last month.
The four-strong Kenyan challenge is led by reigning world, Olympic and Commonwealth champion Conseslus Kipruto, who returned in August after a stress fracture in his foot.

The noise cranks up - here's Mutaz Essa Barshim's final crack at 2.33m...
...and he does it! What a superb jump! The crowd go bananas behind him. He's still in the competition.
Men's high jump final
Ouch!
Cuba's Luis Enrique Zayas gets his final attempt at 2.33m all wrong and ends up headbutting the bar off. That'll sting.

Muhammad and McLaughlin are EXHAUSTED as they unite for photos. Hands on knees, deep breaths.
No wonder. THOSE TIMES!

We thought the lane draw was going to be a factor but Dalilah went out very, very quickly and took it to McLaughlin.
That was a fantastic race, I thought we were going to be treated to something special.
Michael knew (part II)...

Two-time world 110m hurdles champion on BBC TV in Doha
Absolutely great competition. Dalilah knew that Sydney was inside her but she was much snappier over the barriers. Sydney floats a little bit. She'll have her day but Dalilah was so up for this.
