Ben Pattison didn't think he'd get his shot at the Olympics when he was told surgeons would have to brun off part of his heart in 2020.

Against all the odds, here he is, via a bronze medal in the 800m in Budapest's World Championships last year.

Only Seb Coe has covered the distance faster.

You can see him in action from 10.55am in the first round of the men's 100m. What a story.

I promise he isn't as terrified of climbing as he looks here.

Twenty-two-year-old Yorkshire man Hamish McArthur has brought a 14-strong contingent of fans out to his event today and is currently sat third as he grapples for a place in the final. He only found out he was coming in June - how far can we go?

We also have Toby Roberts in this event and he places seventh so far, with the top eight making the final.

Nobody paid attention to Cole Hocker last night. Not until he doused the supposed 1500m duopoly with cold water.

Josh Kerr was meant to be the golden boy, and in the end, silver is nothing to be ashamed of. He ran a superb race and is now a two-time Olympic medalist. But it's his rivalry with Norwegian foe Jakob Ingebrigtsen that many thought would light up the final.

Now, on the comfort of the Eurosport sofa, Kerr has opened up on their rivalry - and revealed there is 'real beef' and what makes him 'sting'.

Sign me up for the speedwalking. At the pace I overtake the dawdlers on the streets of London, I'd have a medal in the bag.

Spain claim the first gold of the day, and I would say they did it at a canter, but that would be too fast.

Maria Perez and Alvaro Martin are seen here celebrating their marathon race walk mixed relay triumph. You'll never sing that.

Here is Cindy Sember's run from before, by the way. Any budding hurdle-clearers, take note.

After a slow start, the Michigan-born athlete found her groove.

Having come fourth in the 100m hurdles in Rio in 2016, she's back with a vengeance.

Plenty to be optimistic about in the men's 3m springboard diving.

After two attempts, Jack Laugher places fifth and Jordan Houlden (pictured) is seventh. Three contestants have even dived three times, so of course they'll have a points advantage. The top 12 qualify for the final so it's plain sailing so far.

Andrea Spendolini-Sirieix was left in tears after finishing sixth in the 10-metre platform and bravely admitted that three years ago she 'did not want to be alive'.

She is already a hero to so many, as her father, celebrity chef Fred Sirieix, pointed out - and a bronze medalist alongside Lois Toulson.

Now she has shared an emotional message won Instagram. It's a long way, and very heartfelt.

In the latest instalment of his Olympics Breakfast Briefing, which has become its own institution over the last fortnight, Redgrave reflects on another day of highs and lows for Team GB and previews the action waiting for us today.

Cindy Sember has come second in her women's 100m hurdles heat with a time of 12.72s. A positive start to the day as she's into the semis. .

'It felt pretty good. I have a lot more in the tank but it was good to get the nerves and jitters out. I'm blessed to be here and I'm happy and healthy,' she told BBC Sport.

'I'm ready for a medal. I'm capable. With God's grace I'll be alright.'
