Gabby Logan introduces day six of the World Championships in London, with Mo Farah beginning his quest for a third successive 5,000m title and the medals being decided in the women's 400m, men's 400m hurdles and women's shot-put. It is 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. Farah came into these championships seeking a fifth successive global 5,000m-10,000m double. Five days after his exploits in the 10,000m, the 34-year-old is expected to reach the 5,000m final without any alarm. Reigning women's 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. 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, with Olympic champion Kerron Clement among those he has to beat. Michael Johnson leads the analysis, with Steve Cram, Andrew Cotter, Brendan Foster and Steve Backley among the commentators. And Ore Oduba is joined by special guests to look back on the day's highlights.
