Men's marathon final (21:59 BST)
Later on tonight, the men's marathon gets under way, with Callum Hawkins flying the flag for Great Britain.
He was fourth in 2017 and set a new PB in finishing 10th in this year's London Marathon.
Last time he tried to win a marathon gold medal - at last year’s Commonwealth Games in Australia - he collapsed with heatstroke and dehydration.
But the Scot has revealed a secret training weapon: using a stack of heaters while on a treadmill in his garden shed to replicate the desert conditions in Doha.
“I got it up to 39 degrees at one point,” he said. “It’s a big proper shed and not a wee tiny one.”

Men's 4x100m relay
GB's silver medal-winning men's relay team have been speaking to BBC TV:
Adam Gemili: "We were always pushing for the gold but the Americans were better than us.
"We ran a new British record. We tried our best and hopefully it was a good show for the crowd.
"Leaving with something is great and it puts a spark in us for next year."
Zharnel Hughes: "I think I strained my hamstring maybe. Tonight I came out here and gave it my very best regardless. I pulled it just before I handed over the baton but I knew I had to give it to Richard regardless because I wanted the guys to get a medal. I did my best and the guys came away with a medal. I'm happy, we're going back home with something around our neck.
Richard Kilty: "It's absolutely incredible. It took an American record, the second fastest time ever to beat us. We ran a new European record.
"Zharnel is a proper warrior. When I saw him flying down the straight, I heard something happen so I knew I had to slow a bit.
"We came out here as brothers and we're buzzing."
Nethaneel Mitchell-Blake: "Phenomenal effort by the guys. I'm proud of the boys. It gives us fuel for the fire for next year. Let's enjoy the moment right now though."

Quite depressing really.

Women's triple jump
While we've had all that commotion on the track Venezuela's Yulimar Rojas has wrapped up the triple jump competition by a good 40 centimetres.
Nobody could get near the 23-year-old who posted 15.37m in the second round.
Jamaica's Shanieka Ricketts took silver with a distance of 14.92m, with Colombia's Caterine Ibarguen (14.73m) taking bronze.

Michael Johnson
Four-time Olympic gold medallist athlete on BBC TV in DohaThat is a stunning team with Lyles, Coleman, Rodgers and Gatlin.
The changeovers weren't the best, far from it, but they knew if they could get the baton around that they could win with the amount of speed they had.
The US have so much speed and with Lyles on the end he was never going to give it up.

Women's 4x100m relay final
GB's silver-medal winning 4x100m relay team have been speaking to BBC TV:
Asha Philip: "You know we have a quality set of girls, Imani wasn’t feeling 100% so she stepped back and said can someone step in for me because I am not feeling comfortable."
Dina Asher-Smith: "I think we all handled the pressure between us which is testimony to how much experience we have got as a squad. We almost ran a pb without practicing any of the changes in the warm-up area. It's been a good champs but obviously it's a team event."
Ashleigh Nelson: "Yesterday I was laughing and today I'm crying because it’s my first time running real in a champs since 2014, it means a lot to me, my coach and my family."
Daryll Neita: "I'm just so proud of us girls, the anchor leg was a great leg to run and we're showing we have strength in depth in this team, Last minute changes but we can still get the job done."
