  1. 'A young athlete with good technique'

    Women's 200m semi-finals

    Michael Johnson
    400m world record holder on BBC TV

    "Looking at Bianca Williams, she didn't get a good turn against these world-class competitors. It was tough for her. She's a young athlete, with very good technique but she didn't have the pace. "But the issue is to get more strength, speed and endurance compared to likes of Candyce McGrone and Elaine Thompson."

  2. 'Centimetres from a medal'

    Women's hammer final - Hitchon throws 73.65m

    That was a phenomenal throw from Sophie Hitchon. Something is happening with this event in Britain with Nick Miller and Mark Dry also doing well. Sophie knows now she is centimetres away from a medal.

  3. 'I'm loving my time here'

    Women's 200m semi-finals

    There are a lot of ladies that have improved this year. To make the final was always going to be tough. My starts are always rubbish, the straights are normally the better part. But I don't have anything bad to say. I came here with low expectations, and I'm loving it here. I had such fun and I'm loving my time here.

  4. 'British sprinters have belief'

    It's a very different championships with America not performing as you would expect. A lot of the Brits now believe in themselves and feel we can compete. The Americans are just human with two legs and two arms.

  5. Hitchon fourth in hammer

    Kerpow! Poland's Anita Wlodarczyk is jumping and fist pumping, unable to contain her excitement at breaking the championship record with an 80.27m effort. Needless to say, she retains the lead with that one. 

    Good news too for Britain's Sophie Hitchon as she's broken the national record and moved to fourth place with a  73.65m throw

  6. Asher-Smith making history

    Teenager Dina Asher-Smith set a personal best 22.22 seconds in the 200m heats on Wednesday. That time would have won her a medal at the last 10 World Championships (gold in 1997, 2001, 2003 and 2011.

    The Briton will race in the third semi-final, at about 12:51 BST, so we haven't long to wait.

  7. Get involved #bbcathletics

    Tucker Larke:  Surely if Jonathan Edwards does lose his triple jump WR that's a good thing? Shows his event is progressing.

    Michelle Bond:  Could Aries Merritt maybe have a little word with Gatlin about being a lovely, humble, nice guy? Just a thought.

  8. Thompson eases into 200m final

    Jamaica's Elaine Thompson turned on the cruise control and still won her semi-final in 22.13. America's Candyce McGrone is the second automatic qualifier in 22.26. 

    Bianca Williams (22.87) was seventh, overrun on the bend, and that's end her participation in the event. 

  9. 'Perfect conditions for sprinting'

    Tom Fordyce
    Chief sports writer in Beijing

    "Hottest night of the championships so far in the Bird's Nest, a sticky heat that beads the brow even when you're only racing over a laptop keyboard. There isn't a sniff of a breeze; put those two things together, and you've got perfect conditions for world-class sprinting. Who will cash in - Bolt or Gatlin; Allyson Felix, Shaunee Miller or Chrissie O?"

  10. 'Gatlin is unpopular because of a lack of contrition'

    If you missed the enthralling Gatlin debate earlier which involved Gatlin's agent, Steve Cram and Michael Johnson, you can watch it all by clicking here. 

    Here's more from BBC commentator Steve Cram on the subject: "Justin Gatlin, over the years, has not done himself any favours. I've never heard him apologise to the sport. He said his biggest mistake was that he chose the wrong physiotherapist.

    "Usain Bolt is popular because of his lack of arrogance; Gatlin is unpopular because of a lack of contrition. No-one wants to see people vilified. Opinions are opinions. Renaldo says we have to be neutral but I don't think we do.

    "We have to give strong opinions because we need to make some changes in the sport. Part of these changes are whether people like Justin Gatlin deserve the chance to come back?"

  11. Pichardo first, Taylor second

    Pedro Pichardo is unable to better is first effort of 17.52 on his second attempt (17.44m). The Cuban still leading the standings, though, but Christian Taylor is second - 17.49m on his second attempt. It's hotting up.   

  12. 'Lawrence has a lot to learn'

    Men's 110m hurdles semi-final

    Michael Johnson
    400m world record holder on BBC TV

    "You can see the contrast between Lawrence Clarke and David Oliver in terms of style.

    "Lawrence has a lot to learn and he hit the last one really hard. But it was a gallant effort from him."

  13. They're so quick - Clarke

    I knew this race was a do or die race. The first five was the fastest five I've ever done but by the end I was just too tired. I came fourth in the Olympics but God they're quick. It's a year to go to the Olympics and that's what I've been dreaming of. If I can hang on to my fitness I will get there.

    PtheP:If Omar McLeod could actually hurdle he might win the hurdles ... 9/10 down!

  15. France's Bascou wins 110m hurdles semi

    The third 110m semi-final is won by Dimitri Bascou in a personal best 13.16. The Frenchman beat David Oliver into second by 0.01 seconds. 

    Britain's Lawrence Clarke? The Eton-educated so-called poshest man in sport was seventh in 13.53. Clarke's race unravelled towards the end. 

  16. Hitchon eighth in hammer

    Britain's Sophie Hitchon improves on her first-round throw, balletically twirling, brutally throwing. 71.44m is her effort which leaves her currently in eighth place. 

    Poland's Anita Wlodarczyk, the world record holder, leading the way with 78.52m. It would be a major upset were she to lose out on gold this afternoon. 

  17. Pichardo takes triple jump lead

    Pedro Pable Pichardo, triple P to his friends, produces a 17.52m opening jump in the triple jump final. 

    Christian Taylor next and the Olympic champion, talking to himself on the runaway, hop, skips and jumps 16.85m. The speed of the track troubling the American perhaps? 

  18. 'Merritt phenomenal'

    Allison Curbishley
    BBC athletics expert on Radio 5 live

    There probably wouldn't be a more popular winner here if Aries Merritt wins gold. It is phenomenal that he has come here given what he is going through, and that was a great run. It's unbelievable that he could be going into hospital with a gold medal.

  19. Merritt through to 110m hurdles final

    The second men's 110m semi-final is upon us and it features the remarkable Aries Merritt, who wins in a season's best 13.08. How quickly would he go with two working kidneys? 

    Second was Jamaica's Omar McLeod, the surprise winner if the Jamaican trials.
