  1. Until tomorrow.... farewell

    Karsten Warholm

    That's us done for today. Thanks for sticking with us.

    But you could hardly leave early could you with this man claiming back-to-back world titles.

    Here's a selection of our top content today to keep busy with:

    If you scroll down on this page you will find highlight videos of Monday's best bits.

    We'll see you again on Tuesday and we've posted what you can look forward to below this entry. The BBC Sport live text will be up from around 14:00 and once more you'll be able to watch the action live within it or read our updates.

    Thanks so much for your time today. Kudos to Karsten.

  2. Tuesday's action...

    So what is on the agenda tomorrow? Firstly, let me stress the BBC Two coverage will run 13:45-21:00 BST.

    Four gold medals to be won in all, notably in the men's pole-vault and then in an eye-catching 200m final at 20:40 BST. Adam Gemili will fly the flag for Great Britain in that one after qualifying nicely today.

    There's also a men's 800m final and a women's javelin final to conclude the four medal events.

    Action starts with hammer qualification at 14:30 BST and runs all the way through to the 200m final at 20:40 BST. That means you can follow from your desk and while eating your dinner at home.

    Right then. There are still thousands of you reading this page so how's about we have a quick catch up on today's highlights...

  7. 'Block Cam' blocked

    If you have been watching these championships, you may have noticed some new camera angles on the blocks. But they are short-lived following complaints...

    The close-up camera shots of sprinters settling into their starting blocks - the "Block Cam" - are being restricted after complaints from female German sprinters Gina Luckenkemper and Tatjana Pinto.

    The world athletics body IAAF agreed only to show close-ups of athletes crouched, awaiting the starting pistol.

    Luckenkemper and Pinto complained they had not been consulted about the intimate cameras installed in the blocks for their 100m races.

  8. The latest medal table...

    Dina Asher-Smith's 100m silver remains Great Britain's only take from events in Doha thus far. A long way to go though.

    After a gold tonight, I can only assume the mighty Uganda don't make into onto this graphic as a result of alphabetical order.

    If my mathematics are correct, USA picked up five medals today, none of them gold.

  10. 'I thought I was going to die'

    Karsten Warholm

    World 400m hurdles champion Karsten Warholm speaks to BBC Sport: "This was a very tough race. I actually felt my heart was going to stop. I thought 'I'm going to die but it's going to be worth it'.

    "This is only the beginning and I am very lucky to win. It's deserved but in the future these guys will be tougher to beat. Tomorrow I have to get up and work again. That is what I love.

    "Norway is a small country. For me to be showing off on the world stage it's better than anything else."

    Colin Jackson

    Two-time world 110m hurdles champion on BBC TV in Doha

    It was a solid, perfect race for Karsten Warholm in those circumstances.

  12. Ouch!

    Men's 400m hurdles

    This is how it feels to run round a track at breakneck speed jumping over hurdles every 13 strides.

  13. 'They just can't'

    Men's 400m hurdles

    Steve Cram

    BBC Sport athletics commentator in Doha

    Karsten Warholm

    Karsten Warholm retains his title. Times don't matter. It was still a quick race and he is the champion again. He was great.

    The thing about him is you know what he is going to do. He says "follow me, beat me, run faster than me."

    And they just can't.

  14. The showpiece final...

    Men's 400m hurdles

    Men's 400m results

    So the 27-year-old world record survives - for now - but Karsten Warholm is certainly a name you can expect to hear plenty about when Tokyo 2020 comes around next summer.

  15. 'He is a star of this sport'

    Men's 400m hurdles

    Michael Johnson

    Four-time Olympic gold medallist athlete on BBC TV in Doha

    It wasn't the world record and none of those guys got close to the times they ran earlier in the season.

    Ultimately it was [Karsten] Warholm and the strength that he has and consistency.

    He does the same thing every single time and that's how you win gold medals and championship medals. He is a star of this sport no doubt about it.

  16. Gold medal for Norway

    Men's 400m hurdles

    Warholm

    All that screaming, chest pumping and face slapping before the gun paid off. Karsten Warholm, you tough cookie...

    The 23-year-old did the damage early, held things together and after the final hurdle, while Rai Benjamin wanted some of the action, the champion was just strong, solid and not giving up an inch.

    No world record but it's back-to-back world titles for the hurdling star.
