Gabby Logan introduces day six of the championships from the London Stadium, as Mo Farah begins his quest for a third successive 5,000m world title, and the medals are decided in the women’s 400m, men’s 400m hurdles and women’s shot put.
It’s also the semi-finals of what looks to be a wide-open men’s 200m event, while Britain’s world indoor bronze medallist Lorraine Ugen attempts to secure safe passage to the women’s long jump final.
Mo Farah came into these championships seeking a fifth successive global 5,000/10,000m double. Five days after winning the 10,000m, the 34-year-old will be expected to reach the 5,000m final.
Reigning 400m champion Allyson Felix proved her form and fitness at this venue last month by setting the fastest time of 2017, making her the favourite to win a tenth world title tonight. In the men’s 400m hurdles, world leader Kyron McMaster is vying to win a first medal of any colour for the British Virgin Islands — Olympic champion Kerron Clement will be among those he has to beat.

It’s all set to be a cracking head-to-head between Allyson Felix, the most decorated woman in US track and field history, and Shaunae Miller-Uiboof the Bahamas. Miller-Uibo made headlines at the Rio Olympics last year when she desperately dived over the line to pip Felix to the gold. And this could be another nail-biting finish. Miller’s in great form so I’m backing her to win this — and without having to resort to a last-gasp dive! I’m also tipping her to have enough in the tank to win the 200m in two days’ time. She’s that good.
Keep an eye out for Great Britain’s Emily Diamond. She was a key part of the women’s 4x400m relay team that won bronze in Rio so she’s more than capable of springing a surprise.
Mo Farah begins his defence of the 5,000m crown in tonight’s heats (8.05pm BBC2).
